GNC Engineer, Phased Array Devices

About the role

Join the Starshield team to develop guidance, navigation, and control algorithms for user terminals connecting ground assets to space-based networks. You will build production software that manages beam-steering and navigation for high-velocity platforms in support of national security missions. In this capacity, you are responsible for architecting resilient GNC solutions that ensure continuous connectivity in contested environments. The role requires translating high-level mission objectives into deterministic control logic for complex phased array systems. You will operate at the intersection of real-time software engineering and precision navigation theory. Success in this position demands rigorous analysis and a commitment to system robustness under dynamic conditions. You will directly contribute to the operational integrity of strategic communication links.
