GNC Engineer

True Anomaly is a company focused on building innovative technology for space security and sustainability. They are seeking a GNC Engineer to own the development of Guidance, Navigation, and Control systems, design GNC flight software, and collaborate across teams to ensure integration of GNC functionalities.

Responsibilities

• Own all aspects of Guidance, Navigation, and Control (GNC) system development, including architecture definition, algorithm design, verification, hardware integration, and on-orbit operations
• Design, test, and validate GNC flight software and embedded algorithms for spacecraft operating in LEO, GEO, and other orbit regimes
• Develop and maintain spacecraft Attitude and Orbit Determination & Estimation (AOD/AOE) algorithms, including sensor fusion and filtering frameworks (e.g., EKF, UKF, batch least-squares)
• Conduct trade studies and provide design recommendations for GNC hardware such as reaction wheels, torque rods, thrusters, star trackers, sun sensors, IMUs, and RF/optical navigation sensors
• Develop GNC algorithms and implement them in flight software; verify performance and robustness through high-fidelity simulation, Monte Carlo analysis, and hardware-in-the-loop testing
• Design, implement, and improve high-fidelity 6-DOF simulation environments for SIL, HIL, and advanced mission analysis
• Utilize and enhance frequency-domain and time-domain control analysis tools to ensure stability margins, disturbance rejection, and performance in off-nominal conditions
• Define system- and subsystem-level GNC requirements, interfaces, and verification plans in collaboration with systems engineering
• Work cross-functionally with avionics, propulsion, software, mission operations, and systems teams to ensure seamless integration of GNC functionality
• Support on-orbit commissioning, system calibration, maneuver planning, and anomaly resolution throughout mission operations
