Staff Engineer, Flight Controls - X-BAT (R4813)

Job Description:

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.
• Mentor, teach, and up-skill younger engineers.
• Ability to obtain a S//SAR level security clearance desired.
