Engineer II, Flight Controls - X-BAT (R4816)

What you'll do

• Design and implement flight control laws and supporting logic across multiple flight regimes.
• Build and mature high-fidelity 6DOF simulation environments used for control development and ensure accurate pre-flight performance predictions.
• Execute verification activities, including linear analysis, Monte Carlo campaigns, disturbance/sensitivity/degraded operation testing, and HIL validation.
• Diagnose and resolve simulation-to-test mismatches, including unidentified dynamics and modeling gaps.
• Support flight test operations and contribute to rapid iteration between flights.
• Work closely with propulsion, aero, actuation, sensors, state estimation, and autonomy teams to ensure accurate integrated system performance in the 6DOF simulation environment.

Required qualifications
