Principal Flight Software Engineer This range is provided by InnoForge. Your actual pay will be based on your skills and experience — talk with your recruiter to learn more. Base pay range $180,000.00/yr - $250,000.00/yr InnoForge are partnering with a venture-backed space and national security company developing a first-of-its-kind space-based system that redefines how assets are deployed, maneuvered and operated in orbit. We’re seeking a Principal Flight Software Engineer to lead the design and development of mission‑critical flight software for a novel, propellant‑free electromechanical deployment and interceptor system. This technology underpins a new generation of space architectures focused on scalability, affordability, and operational surprise. You’ll work in a fast-moving, cleared prototyping environment, taking hardware from prototype through flight demonstration and into operational deployment. This is a rare opportunity to own software architecture end‑to‑end for a system that will fly and directly shape future space and missile‑defense capability. What You’ll Do Architect, implement, and deliver real‑time flight software supporting guidance, navigation & control, autonomy, telemetry, and fault management. Own software architecture and system‑level performance for a first‑of‑its‑kind space system. Lead technical design reviews, verification, validation, and integration with hardware and GNC teams. Develop high‑reliability embedded software in C/C++ (and/or Rust) within RTOS or bare‑metal environments. Drive software processes, mentor engineers, and establish best practices as the system matures toward flight. Support hardware‑in‑the‑loop, spacecraft‑in‑the‑loop , and flight testing in an agile, prototype‑driven program. What You Bring 7+ years of experience developing embedded or real‑time software for space, aerospace, defense, or other mission‑critical systems . Deep proficiency in C/C++ and a strong understanding of deterministic, real‑time system behavior. Experience owning software across the full lifecycle — from early concept through integration, test, and operations. Comfort operating in ambiguous, fast‑paced environments where first‑principles thinking is required. Ability to obtain and maintain a U.S. Security Clearance (U.S. citizenship or permanent residency required). Why This Role Work on a system that does not exist anywhere else today Clear roadmap to a 2027 flight demonstration Multi‑year funding and government backing Meaningful equity offered to early technical leaders Real ownership, real hardware, real impact If you’re motivated by hard problems, real missions, and the chance to build something that will define a new category in space operations, we’d love to speak with you.
