Senior GNC Engineer: Spacecraft Autonomy & Flight Hardware

Fruition Group US; Los Angeles (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Fruition Group US seeks a senior engineer to own spacecraft guidance, navigation, and control algorithms. You will advance from underlying math to flight software, implementing robust state estimation and control on hardware.

Expect hands-on work with MATLAB/Simulink, Python, and C/C++ in a real spacecraft environment. You will model orbital dynamics, fuse sensor data, and validate designs through hardware-in-the-loop testing, while collaborating with vehicle architecture and systems engineers

Qualifications

• 5+ years in guidance, navigation, or control for spacecraft or autonomous platforms.
• Strong background in GNC theory and practice, with real hardware exposure.
• Experience moving algorithms from lab to flight hardware within embedded systems.

Responsibilities

• Own algorithms for orbit relative motion, close-proximity and formation operations.
• Develop orientation control systems and sensor fusion for accurate state estimation.
• Model orbital dynamics and external disturbances for robust design.
• Integrate multi-sensor data into a single position/trajectory picture.
• Transition from simulation to embedded flight code and validation on hardware.
• Stress-test designs against uncertainty and failure using statistical methods.
