  • Design, develop, test, and verify flight algorithms for the GNC subsystem and support flight software qualification testing.

  • Analyze and test the spacecraft GNC subsystem performance using simulations and other analytic tools.

  • Perform analysis to support early design phase concept development, including actuator sizing and placement, sensor selection and placement, and predicted performance assessments.

  • Develop simulation models for sensors, actuators, system dynamics, and the space environment.

  • Document designs, analysis, and test results and create presentation materials.

  • Present designs, analysis, and test results to internal and external customers.

  • Provide technical leadership, direction, and mentoring to other technical employees.
