• Contribute to guidance strategy, navigation solutions and vehicle control techniques.
• Support trajectory design, mission analysis and flight performance assessment.
• Develop and maintain high-fidelity simulation environments for design, development and verification.
• Model vehicle dynamics, environmental effects, sensors, actuators and subsystem interactions.
• Implement and integrate GNC algorithms within production flight software.
• Create analysis, testing and automation tools using C++, Python and MATLAB.
• Investigate anomalies and unexpected behaviour in simulation, testing and flight operations, driving issues to root cause.

Qualification Checklist

• Background in GNC, flight dynamics, astrodynamics, aerospace engineering, robotics or a related discipline.
