Facility Security Officer (TS/SCI)

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price - and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger - helping develop the solar system and build toward a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a high-growth Series D-funded company, we'd love for you to apply.

The Role

K2 Space is seeking a Facility Security Officer (FSO) to lead our industrial security program, ensuring compliance with 32 CFR Part 117, NISPOM, and DoD/customer security requirements. You'll partner closely with the Head of Facilities, IT Security & Compliance Lead, and government security stakeholders to safeguard classified information across multiple sensitivity levels and build a strong security culture as K2 scales.

This is a high-impact, largely independent role for a self-motivated security professional ready to work across the full organization - from Program Managers and Engineering to Legal, HR, and IT.

• Submit and maintain Facility Clearance (FCL) sponsorship packages; ensure ongoing FOCI compliance
• Keep business lines informed of upcoming security requirements; update SF312s and work with Legal to keep DCSA organizational records current
• Develop and deliver security training - SCG, CUI, and OPSEC - with the SETA team and Program Managers; manage and maintain NISS
• Provide security-section input for RFPs, BAAs, and related proposal documentation
• Review PWS/SOWs and generate DD Form 254s, providing guidance on flow-down security requirements
• Conduct security briefings, including indoctrinations, annual refresher training, and event-driven sessions
• Investigate suspected security infractions or violations, document findings, and recommend corrective action
• Own the full lifecycle of classified information - safeguarding, tracking, storage, reproduction, destruction, and secure transmission (marking, wrapping, mailing) - in line with NISPOM and ICD requirements
• Prepare and maintain Program Protection Plans, Security Classification Guides, and Transportation Security Plans
• Support the ISSM/ISSO with classified information systems maintenance and monitoring
• Respond to after-hours alarms and security incidents as needed
• Report key site and program security status to the Director of Security

Qualifications

• Bachelor's degree in a relevant field
• Active Top Secret/SCI clearance
• 10+ years as a Facility Security Officer or Security Manager supporting DoD and Intelligence Community programs
• Strong command of NISPOM, and DoD security protocols
• Excellent written and verbal communication skills, with experience briefing executives, employees, and government stakeholders

Compensation and Benefits

• Base salary range for this role is $120,000 - $170,000 + equity in the company
• Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
• Comprehensive benefits package including unlimited paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!

Export Compliance

As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.”

The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
