• Implements and validates GN&C flight software (MATLAB/Simulink models and C/C++ prototypes) and integrate with testbeds and avionics
• Applies astrodynamics and flight mechanics to mission design, novel orbit concepts, and trajectory optimization
• Develops powered and unpowered guidance laws and autonomy tools for on-orbit operations
• Supports troubleshooting of operational anomalies, functional tests, and service incidents
• Produces concepts of operations, simulation artifacts, and test procedures to enable rapid iteration from prototype to flight test
• Collaborates with cross-functional teams (systems engineering, avionics, test, and business development) and communicate technical tradeoffs to stakeholders
• Independently identify inefficiencies, propose solutions, and implement reusable tools and automations
