GNC Engineer III

Space is a war fighting domain. True Anomaly seeks those with the talent and ambition to build the technology that secures it.

True Anomaly delivers decisive capabilities for space superiority. We build autonomous spacecraft, advanced payloads, mission software, and space-based interceptors — enabling the U.S. and its Allies to secure the space environment and counter threats from the ultimate high ground.

Be the offset. We create asymmetric advantages with creativity and ingenuity.

What would it take? We challenge assumptions to deliver ambitious results.

It’s the people. Our team is our competitive advantage and we are better together.

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.
