· Support simulation environment development (MATLAB/Simulink, Python)

· Conduct hardware-in-the-loop (HIL) simulations and software testing

Required Qualifications

· BS in Aerospace/Mechanical Engineering, or other relevant areas

· 5+ years of experience in flight control, stability, or vehicle dynamics

· Demonstrated experience with control law development and implementation

· Strong skills in MATLAB/Simulink, Python, or equivalent modeling tools

· Experience with multi-phase flight regimes and dynamic simulations

· Strong verbal and written communication skills

· US citizen, with eligibility for government security clearance

Preferred Qualifications

· 3+ years of experience with missiles, UAVs, or other high-speed flight control systems

· Background in model validation, HIL simulation, or embedded control testing
