Space industry certifications: which ones space job postings name, and what each takes (2026)

Which certifications rocket, satellite and spacecraft employers actually name, counted every day across every open space industry job posting on SpaceJobs.Now, what each one takes to earn, and which are worth your time for the role you want.

Certifications are one of the few parts of a space job application you can change in weeks rather than years. A degree takes four years and experience takes longer, but a soldering certification takes a few days, a Six Sigma Green Belt a few weeks and a PMP a few months. The question is which ones employers actually ask for, because a certificate nobody asks for is time you could have spent building something.

So this guide starts from the postings. Every day our research on the skills space employers ask for reads every open role on SpaceJobs.Now ( 18,705 today, from the job boards of about 150 space employers, among them SpaceX, Blue Origin, Rocket Lab, NASA, JPL, Lockheed Martin and Northrop Grumman) and counts how often each certification or certifiable skill is named; every count below is that reading, today's. Then, for each certification, we read the issuing body's own pages for what it takes: eligibility, the exam, the fee and how long it lasts.

The short version:

• GD&T is named in 1,353 postings ( 7.3%), more than any other credential-like skill, and in 32.7% of mechanical, structures and thermal postings and 19.0% of manufacturing and technician postings. It is a skill first and a certification second.
• AS9100, the aerospace quality standard, is named in 737 ( 4.0%), and in 30.0% of quality and mission assurance postings. It certifies companies, not people, but people who know it are hired for it.
• Six Sigma is named in 693 postings, and 325 ask for a belt or certification, mostly in quality, manufacturing and program management.
• The PMP is named in 417 postings, 7.6% of programs and business postings (more among program and project managers alone).
• Security+ or the DoD 8570/8140 baseline is named in 311, CISSP in 184: in software and IT postings, 10.0% name the first and 7.0% the second.
• IPC soldering and harness standards are named in 330, 7.9% of manufacturing and technician postings; the FAA Airframe and Powerplant certificate in 116, 4.2% of them.

The rest of the guide explains each certification in turn, with what the postings say and what the issuer requires, and closes with a way to choose. If you are still deciding which kind of space role to aim for, our guide to getting a job in the space industry is the place to start; for how to present certifications on the page, see the space industry resume guide.

1. What space postings name, by certification

The table counts postings that name each certification or certifiable skill anywhere in their text, as a share of every open posting read, today. A posting that names several is counted once for each; the research table ranks them with the employer naming each most.

Two cautions before reading too much into the shares. First, whether a certification is required or merely welcome differs sharply between them. Reading the words around each mention (whether the nearest cue before it is "preferred", "a plus" or "desired", or "required", "must" or "basic qualifications") in the 18,507 postings open on 3 November 2026, we found:

The rest of each row had neither cue nearby. The split makes sense: most certifications tip a close decision, but Security+ and CISSP are often conditions of the job itself, because Department of Defense rules require certified staff in certain cyber roles (section 8). Second, the overall share hides how concentrated each one is: the PMP is named in only 2.2% of all postings but in 7.6% of programs and business postings, and in nearly a quarter of program management roles alone on 3 November 2026. The next section shows that concentration.

2. Which certifications each kind of role names

Grouped by the board's own kinds of work, the share of each kind's postings naming each certification, read every day ( every kind against every certification):

Grouped instead by the words in their titles on 3 November 2026, the concentration was sharper still: 23.0% of program and project management titles named the PMP, 19.5% of IT and cybersecurity titles Security+ or the 8570/8140 baseline, and 11.3% of technician, machinist and inspector titles an IPC standard.

The pattern is clear enough to act on. For hardware roles, GD&T and the quality standards come first; for program roles, the PMP; for cleared IT and cyber roles, Security+ and CISSP. Software and systems engineering postings name certifications rarely: for those roles, what you have built carries far more weight than any certificate, and the exceptions (Security+ for cleared software work, INCOSE for systems engineering) are covered below.

3. GD&T and the ASME GDTP certification

Geometric dimensioning and tolerancing is the language engineering drawings use to say how much a part may deviate from its ideal shape, and where it is measured from. In the United States it is defined by the ASME Y14.5 standard, and it is the most widely named certifiable skill on our board: 1,315 postings (7.1%), including 27.8% of mechanical and structures roles, 22.2% of manufacturing and quality roles and 14.1% of technician roles. Flight hardware is toleranced tightly and inspected against the drawing, so designers, machinists, inspectors and quality engineers all need to read it the same way.

Most postings ask for the skill rather than a certificate: about 43% of the mentions sit in "preferred" wording and 19% in "required". The certificate that proves the skill is ASME's own Geometric Dimensioning and Tolerancing Professional, the GDTP ( ASME):

• Two levels. The Technologist covers reading and interpreting drawings, and ASME states plainly that "There is no experience requirement." The Senior covers selecting and applying geometric controls, tolerance calculations and datum selection, and for the 2018 edition of the standard it requires three years (36 months) of documented GD&T experience. The Technologist is not a prerequisite for the Senior.
• The exam. For the 2018 standard, 150 scored multiple-choice questions, closed book, up to 4 hours for the Technologist and 6 hours for the Senior. Passing is 74% overall with at least 50% in each section.
• Fees. $395 for the Technologist and $495 for the Senior; retests $225 and $325.
• Validity. "The certificates will have an expiration date of three (3) years from the date of issuance", and each certificate is tied to a specific edition of Y14.5. Renewal ($125) needs no retest, only evidence of at least 24 months of GD&T work in the prior 36.

Who should get it. An inspector, machinist or early-career mechanical engineer who wants a checkable line on the resume gains most from the Technologist: no experience needed, a few weeks of study, and a credential that answers a requirement named in more than one in four mechanical postings. Experienced design and quality engineers can show the skill through their work, and the Senior mainly helps when a role centers on tolerance analysis or drawing standards.

4. AS9100 and aerospace quality credentials

AS9100 is the quality management standard of the aviation, space and defense industries. In SAE's description, AS9100D "includes ISO 9001:2015 quality management system requirements" and adds the aerospace and defense requirements on top ( SAE). It was first issued in November 1999, and the current revision D dates from September 2016.

It is named in 740 postings (4.0%), and in 24.2% of manufacturing and quality roles, 8.1% of technician roles and 3.4% of program management roles. The key thing to understand is what it certifies: a company's quality management system is audited and registered to AS9100, not a person. When a posting names AS9100, it is asking whether you have worked inside such a system: controlled documents and drawings, first article inspection, nonconformance and corrective action, configuration control, and traceability from raw material to the finished part.

There are individual credentials around the standard, and they are training records rather than licenses:

• Internal auditor training. Aerospace suppliers train their own staff to audit against AS9100, and courses are offered by the standards and quality organizations, including SAE and ASQ. Some of these courses are approved by Probitas Authentication, SAE's training authentication body.
• Third-party auditors. The auditors who register companies work for certification bodies and follow a separate qualification route recognized by the International Aerospace Quality Group.

Who should get it. For a quality engineer, quality inspector or manufacturing engineer moving into aerospace, an internal auditor course is a practical way to learn the standard's structure and to show it on a resume. The stronger evidence, though, is work: name the AS9100 processes you have run (first articles to AS9102, nonconformance reports, corrective actions, internal audits) with numbers, as our resume guide suggests.

5. Lean Six Sigma belts

Six Sigma is named in 694 postings (3.7%), and 338 of them ask for a belt or certification: Yellow, Green or Black. The mentions cluster in manufacturing and quality roles (24.0%) and program management (9.0%). Most are preferences rather than requirements: 61% of the mentions sit in "preferred" wording against 8% in "required".

Unlike most certifications in this guide, Six Sigma belts have no single governing body. Companies train and certify their own staff, training providers issue their own belts, and quality associations run their own exams, so the issuer and the evidence behind a belt matter. The best-known independent exams are the American Society for Quality's:

• ASQ Certified Six Sigma Green Belt (CSSGB) ( ASQ): candidates "must have worked in a full-time, paid role" with three years of on-the-job experience in one or more areas of the Green Belt body of knowledge, and "Educational waivers are not granted." The exam is computer-based, 110 questions (100 scored), open book, 4 hours 18 minutes. The fee is $483, and ASQ members save $100.
• ASQ Certified Six Sigma Black Belt (CSSBB) ( ASQ): the same full-time paid role and three years of experience in the Black Belt body of knowledge, plus "one completed project with a signed affidavit or two completed projects with signed affidavits." The exam has 165 questions (150 scored), open book, 4 hours 18 minutes, for $585, with members saving $100. ASQ's recertification page lists the Green Belt as a lifetime certification, while the Black Belt lasts three years and is renewed with 18 recertification units or a retest ( ASQ recertification).

Because ASQ's exams require years of experience, many people start with a Green Belt course from a training provider, which teaches the DMAIC method (define, measure, analyze, improve, control) and the statistics behind it, and often requires a completed improvement project. For a space applicant the project is the valuable part: "Cut machining scrap from 6% to 2% with a DMAIC project; Green Belt, 2025" is evidence, where a certificate alone is a claim.

Who should get it. Manufacturing, quality and supply chain engineers, and program staff responsible for production performance. A Green Belt with a real project is enough for most postings that ask; a Black Belt matters for continuous improvement leads.

6. ASQ quality certifications

ASQ's professional certifications are named in 81 postings, mostly quality engineering and audit roles. Two matter most in aerospace:

• Certified Quality Engineer (CQE) ( ASQ)
• Certified Quality Auditor (CQA) ( ASQ)

Both require "8 years of on-the-job experience" in the body of knowledge, including at least 3 years in a "decision-making" position, in a full-time paid role. Education can replace part of it through one waiver: one year for a trade school diploma, two for an associate degree, four for a bachelor's and five for a master's or doctorate. So a quality engineer with a bachelor's degree needs four years of qualifying work.

The CQE exam is computer-based with 175 questions (160 scored), open book, 5 hours 18 minutes; the CQA has 165 questions (150 scored), with case studies making up about 10 to 15 percent of the test. Each costs $550, with members saving $100. Both last three years and are renewed with 18 recertification units or by retaking the exam.

Who should get them. Quality engineers and supplier quality engineers aiming at senior roles at AS9100-registered companies (the CQE), and internal or supplier auditors (the CQA). Both are respected because they cannot be earned without years of work, which is also why they are rarely asked for at entry level.

7. The PMP for program and project management

The Project Management Professional certificate is named in 415 postings (2.2%), and in 23.0% of program and project management roles, far more than any other credential in that family. It is usually a preference: 66% of mentions sit in "preferred" wording, 10% in "required".

The issuer is the Project Management Institute (PMI). Its current exam content outline sets these requirements ( PMI PMP examination content outline, July 2026):

• Experience leading projects "within the last 10 years in a professional setting": "Minimum 36 months/3 years" with a bachelor's degree or higher, 48 months with an associate's degree, 60 months with a high school diploma, and 24 months with a degree from a PMI-accredited program.
• Training: "at least 35 hours of commercial training in project management aligned with topics covered in the PMP".
• The exam: "180 questions", of which "10 are considered pretest questions" and do not count, in "240 Minutes" with two 10-minute breaks.
• Renewal: "60 professional development units (PDUs) every 3 years" plus a renewal fee.

PMI charges different exam fees for its members and for non-members; check its certification page for the current amounts before you budget.

Who should get it. Program managers, project managers, program control analysts and schedulers who have already led projects for three years or more. For engineers moving into program roles, the PMP signals that you speak the language of cost, schedule and risk that government programs run on, especially when paired with earned value management experience, which 20% of program management postings name.

8. Security+, CISSP and the DoD 8140 baseline

Cybersecurity certifications are the clearest case in this guide of a certification that is a hard gate rather than a nice extra. Security+ or the DoD 8570/8140 baseline is named in 316 postings and CISSP in 188, and they are concentrated at defense primes and government contractors: Lockheed Martin (90 postings naming Security+ or the baseline), Northrop Grumman (54), L3Harris (16) and Amentum (13). Security+ is also one of the few certifications more often required than preferred: in our count, 40% of its mentions sit in "required" wording against 37% "preferred". For CISSP the split is 31% required, 41% preferred.

The reason is a Defense Department rule. People who do cybersecurity work on DoD information systems must hold a qualification matched to their role. The old manual, DoDM 8570.01, defined the baseline as a table of approved certifications by job category and level, and Security+ became the entry ticket for many of them. Its replacement, DoD Manual 8140.03, issued 15 February 2023, ties qualification to the work roles of the DoD Cyber Workforce Framework instead. In DoD's words, its foundational qualifications "are similar to DoD 8570 baseline certifications, however, there are multiple avenues, including DoD skills-based courses and experience", and certifications can carry over from 8570 depending on the work role ( DoD, 8570 to 8140 transition, August 2024). One detail matters for contractors, who hold most space industry cyber jobs: the same document says "Contractors remain under DoD 8570 policy until update of the Defense Federal Acquisition Regulation Supplement (DFARS) authorizes DoD 8140 implementation for contractor personnel", and the experience route "is not authorized for contractor personnel". That is why space postings still say "8570", and why a contractor's quickest way to qualify is still a certification such as Security+.

Clearance comes with it. Of the 316 postings naming Security+ or the baseline, 286 (91%) also mention a security clearance, and so do 155 of the 188 naming CISSP. The certification qualifies you for the role; the clearance qualifies you for the program. Both usually require U.S. citizenship.

CompTIA Security+

From CompTIA's own pages ( CompTIA Security+):

• Current version: V7 (exam SY0-701). In CompTIA's words, "Security+ V8, is expected to launch on or around November 17, 2026" (exam SY0-801), so check which version you are preparing for.
• The exam: "Maximum of 90 questions", "90 minutes", a passing score of "750 (on a scale of 100-900)", with multiple-choice and performance-based questions.
• Experience: none required. For V7 CompTIA recommends "CompTIA Network+ and two years of experience in a security or systems administrator job role".
• Renewal: CompTIA's continuing education program keeps it current, and its fee page lists $150 as the "Total CE fee (three-year period)" for Security+ ( CompTIA CE fees). The exam voucher price is on CompTIA's store and differs by country, so check it there.

ISC2 CISSP

From ISC2's own pages ( ISC2 CISSP):

• Experience: "a minimum of five years cumulative, full-time experience in two or more of the eight domains" of the CISSP body of knowledge. A bachelor's or master's degree in a related field can count for up to one year of it. A candidate who passes without the experience becomes an Associate of ISC2, who then has six years to earn it.
• The exam: in English it is a computerized adaptive test of 100 to 150 items over 3 hours, with a passing score of 700 out of 1,000. ISC2 lists the standard registration fee in the Americas as $749 ( ISC2 exam pricing). A new exam outline takes effect on 15 April 2027. The CISSP page also states that it is approved by the Defense Department under DoDM 8140.03.
• Upkeep: 120 continuing professional education credits over each three-year cycle and an annual maintenance fee of $135.

Who should get them. Security+ is the first certification for anyone aiming at IT, network, cyber or ground systems roles at a defense prime, and for system administrators on classified programs: it is cheap, quick and asked for by name. CISSP comes later, for security engineers, information system security officers and managers with five years in the field. Network+ and CCNA (134 postings) suit network engineers; CISM and CISA (79) suit security managers and IT auditors.

9. IPC soldering and harness certifications

Every satellite and rocket carries kilometers of wire and thousands of soldered joints, and the industry builds them to written workmanship standards. IPC J-STD-001 (soldering), IPC-A-610 (acceptability of electronic assemblies) and IPC/WHMA-A-620 (cable and wire harness assemblies) are named in 311 postings (1.7%), and in 11.3% of technician roles. The leading employers are Blue Origin (55 postings), SpaceX (29), Amazon Leo (19), AST SpaceMobile (13), ICEYE (11) and K2 Space (10): the companies building satellites and avionics at volume.

Space work adds its own layer on top. Of the 311 postings, 73 name the space and military addendum to J-STD-001 (the stricter rules for hardware that cannot be repaired once it is in orbit), 76 name NASA's own workmanship standards, NASA-STD-8739, and 28 say "Class 3", the highest-reliability product class.

IPC certifies people through courses taught by its own certified trainers rather than through a single national exam ( IPC J-STD-001 endorsement program):

• CIS (Certified IPC Specialist): in IPC's words, "an individual that has demonstrated competency in the use and application of a specific IPC standard to class 1, 2, and 3 products". This is the operator and inspector level, earned in a course of a few days with written and practical tests, and most technician postings mean it.
• CIT (Certified IPC Trainer): "an IPC certification for trainers and educators". A CIT can proctor the CIS exam for the standard they are certified to, which is how large employers certify their own technicians in house.
• Validity: IPC's published policies (version 7.2, August 2019) state that "The certification term for the CIS program is 2 years", renewed before it expires ( IPC CIS policies). That is why postings say "current" or "active" IPC certification. IPC revises its policies, so check the current term with your trainer.

Many employers train their own technicians to IPC standards after hiring, and the postings say so: one asks for a "J-STD-001 certified inspector, IPC/WHMA-A-620 certified inspector, or the ability to obtain such certifications". If you already hold one, put the standard, the class and the expiry date on your resume: "IPC J-STD-001 CIS, space addendum, valid to March 2027".

Who should get it. Electronics and harness technicians, assemblers and inspectors, and quality inspectors in avionics. For a technician moving from automotive or consumer electronics into space, a current J-STD-001 with the space addendum is one of the fastest ways to look qualified on paper.

10. The FAA Airframe and Powerplant certificate

The FAA mechanic certificate with Airframe and Powerplant ratings, the A&P, is the license of aircraft maintenance in the United States. It is named in 117 postings (0.6%), and in 7.3% of technician roles, led by SpaceX (38 postings), Virgin Galactic (18), Lockheed Martin (12), Relativity Space (11) and Rocket Lab (10). It is the most "preferred" credential of all in our count: 80% of its mentions sit in preferred wording and 10% in required.

Rockets are not aircraft, and no FAA rule requires an A&P to work on a launch vehicle. Space companies ask for it because it proves what they need from a technician: years of hands-on work on flight hardware, torque and safety wire discipline, and the habit of documenting every step. At Virgin Galactic, which flies a carrier aircraft, the license is part of the job itself.

What the FAA requires, from the regulation itself ( 14 CFR part 65, subpart D) and the FAA's own guide ( Become a mechanic):

• Experience: "at least 18 months of practical experience" with the procedures, practices, materials, tools, machine tools and equipment used in constructing, maintaining or altering airframes or powerplants for one rating, or "at least 30 months" working on both at the same time.
• Or a school: completion of an FAA-certificated aviation maintenance technician school under Part 147 replaces the experience.
• Tests: written knowledge tests, then an oral and a practical test with an FAA designated mechanic examiner. The general requirements (including age 18 and English) are in 14 CFR 65.71.

Who should get it. Military aircraft maintainers already have the experience the FAA accepts, and an A&P turns it into a civilian credential that space employers recognize; the path through the Joint Services Aviation Maintenance Technician Certification Council is built for them. For others, a Part 147 school takes about 18 to 24 months. It is a long route, and worth it mainly for people who want a career in vehicle integration, launch operations or maintenance.

11. NDT and welding certifications

Pressure vessels, tanks and engine parts are inspected for flaws that cannot be seen, and welded to standards written for flight hardware. Both trades have certifications that space postings name:

• Nondestructive testing (NDT): a named NDT level, ASNT or SNT-TC-1A appears in 58 postings, led by Blue Origin (11), SpaceX (10) and Relativity Space (8). Postings ask for Level II in one or more methods: ultrasonic (UT), radiographic (RT), penetrant (PT) or magnetic particle (MT). Many name NAS 410, the aerospace NDT qualification standard.
• Welding: AWS D17.1 (the American Welding Society's specification for fusion welding of aerospace hardware), the Certified Welding Inspector (CWI) or a welding certification appears in 86 postings, led by Blue Origin (23), SpaceX (21) and Relativity Space (7).

How NDT certification works. In the United States most NDT qualification is employer-based: under ASNT's SNT-TC-1A guidance, each employer writes its own written practice and certifies its own technicians to Level I, II or III after training hours, experience and exams ( ASNT, the key "shalls" of SNT-TC-1A). The aerospace standard NAS 410 works the same way, which is why Level II "per NAS 410" is earned with an employer. The portable certification is ASNT's own Level III, for the people who write procedures and certify others. Its eligibility depends on education: 12 months of NDT experience with a four-year engineering or science degree, 24 months with two years of study, and 48 months with neither. The basic exam costs $545 for members and $625 for non-members, and the certificate lasts five years ( ASNT NDT Level III).

How welding certification works. A welder is usually certified to a welding procedure at a specific company, by test coupons that are inspected or broken: the certificate belongs to the procedure and the employer. AWS D17.1 sets the rules for those tests in aerospace work, and the welding postings at launch companies ask for experience to it ("AWS D17.1 Class A welds"). The Certified Welding Inspector is AWS's personal certification for inspectors, earned by exam after documented experience.

Who should get them. Welders and NDT technicians from oil and gas, power or aviation already have the skills, and the useful move is naming the method, level and standard exactly: "Level II UT and PT per NAS 410", "GTAW on Inconel to AWS D17.1". If your past certificates were employer-based, say so: space employers know that is how the system works and will recertify you to their own practice.

12. FE and PE licensure

The professional engineering license is central to civil and building engineering in the United States, and almost absent from space hiring. FE, EIT or PE licensure is named in only 49 postings (0.3%), led by SpaceX (20), Blue Origin (12) and Relativity Space (8), and almost all of them are civil, structural, facilities, fire protection, power and ground systems roles: SpaceX's civil engineers for Starbase and Starship launch pad land development, Blue Origin's launch site civil and ground test structural engineers, Relativity Space's construction and high-power electrical engineers. These are the engineers who design the buildings, pads, utilities and test stands around the rockets, where a licensed engineer must stamp the drawings.

The reason is a legal one. Most U.S. states exempt engineers who work for a manufacturer on its own products from licensing (the "industrial exemption"), so an engineer designing a satellite or an engine does not need a license, while an engineer whose drawings go to a building authority does.

The path, from NCEES, which writes the exams ( NCEES FE exam, NCEES PE exam):

• The FE (Fundamentals of Engineering) exam: computer-based, 110 questions, offered year-round. NCEES lists the fee as $225. Most people take it in their last year of an accredited engineering degree or soon after, and passing it makes you an Engineer in Training (EIT) or Engineer Intern in most states.
• The PE (Principles and Practice of Engineering) exam: in mechanical engineering, 80 questions, for $400 ( NCEES PE Mechanical). Most states require about four years of qualifying experience under a licensed engineer before the license, and each state board sets its own rules.

Who should get it. Facilities, civil, structural and ground support equipment engineers who expect to sign drawings for buildings, test stands or pressure systems; and any engineering student, since the FE is easiest to pass while the coursework is fresh and it keeps the PE route open. For flight hardware engineers it is optional: every posting that requires a PE in our count is a facilities, structures or ground systems role, none of them design work on the vehicle itself.

13. Smaller but useful: INCOSE, Scrum, Part 107 and cloud

Four more groups of certifications appear often enough to matter for particular roles:

INCOSE systems engineering certifications. The International Council on Systems Engineering offers the Associate Systems Engineering Professional (ASEP), for people early in their careers, and the Certified Systems Engineering Professional (CSEP), which requires years of documented systems engineering experience. They are named in 141 postings, mostly at NASA and defense contractors and government services firms (KBR, Booz Allen Hamilton) and at human spaceflight companies (Sierra Space, Axiom Space), where formal systems engineering processes run the programs. In our role count, 5.3% of systems engineering postings name them. Most add them as a preference: systems engineers are hired on experience, and the certification helps most when you are moving into systems engineering from another discipline.

Scrum and SAFe. Agile certifications (Certified Scrum Master, SAFe) are named in 110 postings, concentrated at Lockheed Martin, where 29 of its 30 postings that name one name SAFe, the Scaled Agile Framework. They matter for software leads, product owners and program staff on software-heavy programs.

AWS and other cloud certifications. Cloud certifications are named in only 60 postings, while AWS as a skill is named in 777. Ground software, data and mission operations teams use cloud platforms, and a certification shows a baseline, but space employers mostly ask for the skill and experience rather than the badge.

FAA Part 107. The remote pilot certificate for commercial drone flights is named in 9 postings, almost all at SpaceX, for roles that fly drones for site surveys, inspections and launch photography. The FAA's requirements are short ( Become a drone pilot): you must be at least 16, pass the aeronautical knowledge test at an FAA-approved testing center, and keep current with recurrent online training every 24 months ( 14 CFR part 107). It is an inexpensive credential that sets a photographer, surveyor or site technician apart for the few roles that use it.

OSHA 10 and 30. The Occupational Safety and Health Administration's 10-hour and 30-hour safety training cards appear in 33 postings for construction, facilities and launch site roles. They are short courses rather than exams, and employers often provide them after hiring.

14. How to choose: a decision guide by role

A certification is worth earning when three things are true: postings for the role you want name it, you can earn it in a reasonable time from where you are, and it proves something your resume does not already show. Here is how that works out for each kind of space role, using the shares from section 2 and a few more role families.

Mechanical, structures and propulsion engineers

Learn GD&T thoroughly; certify it if you are early in your career. It is named in 27.8% of mechanical and structures postings and 25.8% of propulsion postings (524 roles), far ahead of anything else. The ASME GDTP Technologist needs no experience and costs $395, so it is the obvious first credential for a new graduate or a designer coming from another industry. After that, nothing else is named often enough to chase: AS9100 knowledge (2.6% to 4.4%) comes from working in a quality system, and the FE exam helps only if you might move into facilities or ground structures.

Manufacturing and quality engineers

AS9100 knowledge, a Six Sigma Green Belt and GD&T, in that order of usefulness, then an ASQ certification once you qualify. Manufacturing and quality is the most certification-heavy family on the board: AS9100 24.2%, Six Sigma 24.0%, GD&T 22.2%. An AS9100 internal auditor course and a Green Belt with a real improvement project cover the first two in a few weeks each. The ASQ CQE takes years of experience to qualify for, and it is worth it for quality engineers aiming at senior roles.

Technicians, machinists, inspectors and assemblers

Pick the credential of your trade and keep it current. Technician postings spread their asks across trades: GD&T 14.1% (drawing reading, for machinists and inspectors), IPC 11.3% (electronics and harness), AS9100 8.1%, FAA A&P 7.3%, welding 4.7% and NDT 4.1%. For an electronics technician that means IPC J-STD-001 with the space addendum; for an inspector, GD&T plus NDT methods; for a welder, qualification to AWS D17.1; for a vehicle technician with aviation background, the A&P. One current, exactly named credential beats a list of expired ones.

Electrical and avionics engineers

IPC knowledge helps; certification is rarely needed. Of 1,294 electrical and avionics postings, 7.7% name an IPC standard, usually as knowledge of workmanship standards ("design to IPC-A-610 Class 3") rather than a certificate the engineer must hold. Engineers rarely need the CIS; knowing the standard and being able to say how your designs met it is what the postings ask for.

Program and project managers

The PMP, once you have three years of leading projects. It is named in 23.0% of program management postings, more than any other credential for any role family except GD&T for mechanical work. A Six Sigma belt (9.0%) helps for production programs. Pair the PMP with earned value management experience, which program postings name even more often.

IT, network and cybersecurity staff

Security+ first, then CISSP when you have five years. IT and cybersecurity is the one family where a certification is often a hard requirement: Security+ or the 8570/8140 baseline is named in 19.5% of these postings and CISSP in 18.2%, mostly at defense primes and nearly always beside a clearance. Network engineers add Network+, CCNA or CCNP (11.8%); security managers and auditors add CISM or CISA (7.3%).

Software engineers

Skip most certifications. Only 2.5% of software postings name Security+ or the baseline (for software on DoD systems) and 1.9% name Scrum or SAFe. Software roles are hired on what you have built and the languages you know: our resume guide covers how to show that. A Security+ makes sense only if you are aiming at cleared software work at a defense prime.

Systems engineers

INCOSE certification is a modest plus. It is named in 5.3% of systems engineering postings. The ASEP is a reasonable step for an engineer moving into systems engineering from a design discipline; for experienced systems engineers, a record of requirements, interfaces and verification on real programs counts for more.

Test and mission operations

Few certifications are named. Test postings (1,154) name GD&T and AS9100 in only 3.5% each and IPC in 2.3%; mission operations postings (282) name almost none. These roles hire on hands-on experience with test stands, data systems and operations procedures, and on clearances for the government missions.

Students and new graduates

The FE exam and the GDTP Technologist are the two certifications that make sense before your first job. Internship and student postings (799) name GD&T in 4.9% of cases and almost nothing else. For students, projects, competitions and internships matter far more than any certificate; see our guide to getting a job in the space industry for where they come from. If you want one credential, the GDTP Technologist (for mechanical students) or the FE exam (in your final year) are the only ones that are cheap, available without experience and named in space postings.

Veterans

Turn military experience into the civilian credential the posting names. Aircraft maintainers can qualify for the FAA A&P on their military experience; avionics and electronics technicians often hold IPC certificates already; cyber specialists usually hold Security+ from their DoD 8570 requirement. Name each one exactly, with its expiry date, and keep an active clearance on the first line of your resume, since 6,039 postings on the board mention a clearance.

A quick comparison

The figures are the issuers' own, as read on their pages on 3 November 2026. Where an issuer does not state a figure on a page we could read, the table says so.

Putting certifications on your resume

Applicant tracking systems at space employers search for the exact names postings use, and recruiters skim for them. Four habits make a certification count:

1. Write the exact name and the standard. "IPC J-STD-001 CIS with space addendum" is found by a search for "J-STD-001"; "soldering certified" is not. The same goes for "ASME GDTP Technologist (Y14.5-2018)", "CompTIA Security+ (SY0-701)" and "FAA Airframe and Powerplant".
2. Give the dates. Many of these expire (IPC after two years, the GDTP after three, Security+ and CISSP through continuing education), and postings ask for "current" or "active" certification. "Valid to March 2027" answers the question before it is asked.
3. Tie it to a result. A Six Sigma belt with "raised first-pass yield on a cable line from 82% to 96%" beside it is evidence; a belt alone is a claim. The same holds for an AS9100 auditor course next to the audits you ran.
4. Put the gatekeepers first. For cleared roles, the clearance and Security+ belong at the top of the resume, where a recruiter sees them in the first seconds; for technicians, the trade certification belongs there too. For engineers, certifications go in their own short section after experience and projects.

Our space industry resume guide covers the rest of the page, with what the same postings ask for in skills, tools and experience.

15. Frequently asked questions

Do I need a certification to get a space industry job?

Usually not. Even the most often named credential, GD&T, appears in 7.1% of postings, and most mentions are preferences. The exceptions are cleared IT and cyber roles (where Security+ or the DoD baseline is often required), some technician roles (IPC, NDT and welding qualifications, often earned on the job) and facilities engineering (the PE). For everyone else a certification is a tiebreaker, and experience and projects decide.

Which certification is most in demand in the space industry?

By the number of postings naming it, GD&T ( 1,353 postings today), then AS9100 ( 737) and Six Sigma ( 693). By how strictly it is required, Security+ and the DoD 8570/8140 baseline, which is named as a requirement more often than as a preference.

Is AS9100 a certification I can get?

Not as a person. AS9100 is the quality management standard a company is audited and registered to. Individuals take AS9100 internal auditor or lead auditor training, which is worth listing on a resume, but what employers value most is experience working inside an AS9100 system.

Is a Six Sigma belt from an online course worth anything?

It depends on the evidence behind it. Lean Six Sigma has no single governing body, so belts vary widely. A belt that required a completed improvement project with measured results is worth listing with the project's outcome; a belt from a short online quiz carries little weight. ASQ's Green and Black Belt exams are the most widely recognized independent ones, and both require three years of experience.

Does SpaceX require certifications?

Rarely for engineers. SpaceX postings name GD&T (165 postings), Six Sigma (155), AS9100 (72), the FAA A&P (38) and IPC (29), mostly for production, quality and technician roles, and almost always as experience with a standard rather than a certificate. SpaceX also names the FE or PE in 20 postings, almost all of them civil, fire protection and power roles.

Do I need a security clearance or a certification first?

For cleared IT and cyber work, both, but they come from different places: you earn a certification yourself, while a clearance is sponsored by an employer for a specific job, and usually requires U.S. citizenship. Getting Security+ first makes you hireable for the cleared roles that will then sponsor your clearance.

How long does it take to earn these certifications?

From a few days to years. An IPC CIS course takes a few days, the GDTP Technologist and Security+ a few weeks of study, a Six Sigma Green Belt a few weeks plus a project, and the PMP a few months of study after three years of experience. The ASQ CQE, CISSP and FAA A&P require years of experience before you can sit the exam.

Will my employer pay for a certification?

Often, after you are hired. Many employers train technicians to IPC, NDT and welding standards themselves, and many pay for the PMP, Six Sigma or Security+ for staff whose roles need them. Before paying yourself, check whether the role you want trains on the job. 75 postings on the board pair a certification with wording such as "or ability to obtain certification", "willingness to obtain within 180 days of hire" or, for the DoD 8570 baseline, "must be able to obtain within 45 days": those employers expect to certify you after you start.

Where can I study for these certifications?

The issuers list their own training and approved providers, and for many of them there are reputable courses online. Below this guide we list the course providers we work with, each marked as a link we earn from; any of the issuers' own pages linked above is a good starting point too.

16. How we measured

Every day the research run behind the skills space employers ask for reads every open posting whose full text SpaceJobs.Now stores, from the job boards and applicant tracking systems of about 150 space employers, and searches it for each certification with a pattern that matches its common names and abbreviations: for example "GD&T" or "geometric dimensioning", "AS9100" or "AS 9100", "PMP" or "project management professional", "Security+", "8570" or "8140", "J-STD-001", "IPC-A-610" or "IPC 620", "A&P" or "airframe and powerplant". A posting naming a certification anywhere counts once for it, whether the certification is required, preferred or mentioned in passing. The first count, on 3 November 2026 over 18,507 postings, was made once from the public job feed; since 4 November 2026 the same patterns run in the research every day, so the counts on this page are today's. The required-and-preferred split and the title-word families below are that first reading.

• Required and preferred. For the split between required and preferred, we looked at the text before each mention for the nearest cue: a "preferred" or "desired" heading or phrase against a "required", "minimum qualifications" or "basic qualifications" one, and at the words right after it ("preferred", "a plus"). Mentions with neither cue are counted in neither share, so the two do not add up to 100%.
• Role families. Postings were grouped by words in their titles (for example "technician", "assembler", "machinist", "welder" or "inspector" for technicians; "program manager", "project manager", "program control", "scheduler" or "planner" for program management). A posting can belong to more than one family.
• Clearance. A posting counts as mentioning a clearance if it names a security clearance, a Secret or Top Secret clearance, TS/SCI or an active clearance.
• Issuer facts. Every eligibility rule, exam format, fee and renewal rule comes from the issuing body's own page or published handbook, linked where it is used, as read on 3 November 2026. Where we could not confirm a figure on an issuer page, we say so rather than quote a third party.

The counts describe what employers wrote in their postings open today. They change as roles open and close, and a posting that does not name a certification may still value it. Postings on SpaceJobs.Now come from employers' own career sites, so the wording is theirs.
