Manufacturing Engineer (Tanks)

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability.

We build fast and iterate quickly. ## Who We’re Looking For We are seeking a skilled and technically driven Manufacturing Engineer (Tanks) to lead the development, qualification, and implementation of manufacturing processes for propellant tanks, pressurant tanks, and pressure vessels supporting our Ranger spacecraft program at our Tulsa manufacturing center.

In this role, you will oversee critical manufacturing operations including forming, machining, welding, inspection, proof and leak testing, and precision cleaning to ensure the production of safe, reliable, and flight-ready spacecraft hardware.

You will play a critical role in developing and scaling repeatable manufacturing processes, tooling, and test methods for some of the most safety-critical components of our spacecraft.

Working closely with design engineering, materials and processes, manufacturing, quality, and test teams, you will support first-article builds, process qualification, and continuous improvement initiatives as Ranger transitions from development into rate production.

This position is ideal for an engineer who combines strong manufacturing engineering expertise with hands-on experience in pressure vessels, welded structures, or safety-critical hardware and thrives in a fast-paced environment where precision, safety, innovation, and mission success are essential. ## Where You’ll Make an Impact - Develop, qualify, and own manufacturing processes for metallic tanks and pressure vessels, including dome forming, machining, weld prep, welding, and post-weld processing - Design and procure weld fixtures, handling tooling, and GSE for tank fabrication and test - Develop and execute proof pressure, leak, and volumetric test procedures and the associated safety controls - Define and implement nondestructive inspection (X-ray, dye penetrant, ultrasonic) and dimensional inspection plans for welds and tank features - Partner with design engineering and materials and processes on tank design for manufacturability, weld joint design, and tolerance stack-ups - Lead first-article builds, process qualification, and qualification tank builds; document results - Lead root cause and corrective action on weld defects, dimensional nonconformances, and test failures - Own cycle time, yield, and cost for tank fabrication and drive improvements as volume increases - Ensure all pressure system work complies with safety standards and mission assurance requirements ## What It Takes - Bachelor's degree in mechanical, aerospace, materials, or welding engineering - 3+ years of experience in manufacturing engineering for pressure vessels, tanks, welded structures, or similar safety-critical hardware ## Nice-to-Have Experience - Experience manufacturing spacecraft, launch vehicle, or aircraft propellant tanks or pressure vessels - Experience with TIG, orbital, electron beam, or friction stir welding of titanium, aluminum, and stainless alloys - Experience with AWS D17.1, NASA-STD-5006, or similar aerospace welding specifications - Experience with proof, leak, and burst testing and pressure system safety (ASME, AIAA S-080/S-081, or range safety requirements) - Experience with NDI methods and acceptance criteria for welds - Experience with dome forming, spinning, or large-part machining - Experience with precision cleaning and propellant compatibility for fluid system hardware - Familiarity with AS9100 quality systems and mission assurance practices for flight hardware ## What You’ll Get - Ownership – Lead the development, qualification, and implementation of manufacturing processes for mission-critical spacecraft propellant tanks, pressurant tanks, and pressure vessels, taking responsibility for production quality, safety, and manufacturing readiness - Innovation – Develop and implement advanced fabrication, welding, inspection, and testing processes supporting next-generation spacecraft propulsion and fluid systems - Impact – Play a direct role in ensuring the safety, reliability, and performance of flight-ready propellant tanks and pressure vessels supporting national security, civil, and commercial space missions - Growth – Join a collaborative, fast-paced engineering and manufacturing team where you can expand your technical expertise, establish scalable manufacturing capabilities, and help shape the future of spacecraft production - Compensation – Competitive salary, equity, and comprehensive benefits including medical, dental, vision, generous leave, HSA, 401(k) matching, and equity participation.x` Location: Tulsa, OK Base Salary: $68,000-80,000 The salary range for this role is an estimate based on a wide range of compensation factors.

Actual salary offer may vary based on (but not limited to) work experience, education and/or training, critical skills, and/or business considerations.
