GNC Engineer, Fleet Management

About the role

Join the Starshield team to manage the full lifecycle of our satellite constellation. You will design constellation geometry and implement control systems for orbit maintenance, station keeping, and collision avoidance. In this capacity, you will act as a primary architect for the guidance, navigation, and control logic that ensures the integrity and longevity of the fleet. Your work will directly influence the strategic deployment and operational resilience of space-based assets. You will own the analysis and refinement of algorithms that govern how our vehicles interact with the space environment. This role requires a deep commitment to precision, safety, and the rigorous standards necessary for successful space operations. You will be responsible for translating complex mission requirements into robust software solutions that maintain optimal constellation performance. Your contributions will be integral to the reliability and effectiveness of our managed fleet.
