Chief Information Security Officer; CISO

The future of aerospace and defense starts here.

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands.

Our mission requires an extraordinary team, specifically one that will mold tomorrow's critical technologies while deploying today's best. We are an intrinsically motivated organization with a passion for solving complex technical problems and empowering each other every day, knowing that there is always room for growth.

Ursa Major is seeking an executive technology leader to serve as our Chief Information Security Officer (CISO w/ clearance). Reporting to the executive leadership team, the CISO will establish enterprise-wide information security ownership across our multi-site engineering, manufacturing, and test facilities. Working in direct, strategic lockstep with our Facility Security Officer (FSO), who leads personnel clearances, physical security, and overall NISPOM facility compliance, the CISO serves as the ultimate authority for digital, technical, and operational cybersecurity.

We are not looking for an administrator who leads from behind a desk or relies on enterprise bureaucracy. We need a builder who leads from the front—an executive with deep roots in Aerospace & Defense (A&D) who knows what mature security infrastructure looks like and possesses the hands‑on drive to build, scale, and mature our systems from the ground up.

Sitting at the intersection of defense compliance, manufacturing velocity, and enterprise IT, you will own the overarching risk management strategy for both unclassified and classified programs. You will champion our hybrid CMMC Level 2 enclave expansion, govern the technical architecture of classified defense enclaves (Secret / SAP), protect critical Intellectual Property, and establish the cyber risk governance required for a high‑growth defense firm preparing for public‑company operations.

• Define and execute Ursa Major’s enterprise cybersecurity and information assurance strategy across all corporate, manufacturing, engineering, and classified program environments.
• Lead from the front to build, mentor, and inspire a world‑class cybersecurity engineering and compliance team, fostering a culture of operational enablement, technical rigor, and deep cross‑functional partnership.
• Direct the continuous advancement and accreditation of our CMMC Level 2 / NIST SP 800-171 architecture, ensuring Controlled Unclassified Information (CUI) and defense technical data flow securely across multi-site operations without impeding engineering velocity.
• In close partnership with the FSO and program security, lead the digital architecture, technical authorization packages, and continuous monitoring of classified information systems (Secret, Top Secret, and Special Access Programs) in strict alignment with RMF, JSIG, NIST SP 800-53, and DCSA standards.
• Establish an enterprise cyber risk register, translating technical vulnerabilities into clear operational and business risk metrics for executive leadership and the Board of Directors.
• Partner closely with IT, Dev Ops, and Digital Manufacturing to embed Zero Trust network segmentation, identity governance (Entra ), and robust endpoint detection into physical shop floors, test stands, and cloud environments.
• Establish a collaborative, locked‑in operating rhythm with the FSO and physical security teams to unify technical cyber defenses with physical enclave controls, COMSEC, and cleared personnel governance.
• Serve as the executive authority for…
