Responsibilities
Contribute to control system architecture and requirements for fixed-wing vehicles, including primary flight control, envelope protection, autothrottle/energy management, and mode logic
Design and implement control laws that account for actuator limits, time delays, and sensor noise
Support system identification and aerodynamic model development using wind-tunnel, CFD, and flight-test data; develop and maintain linearized models
Implement and test fault-handling and reconfiguration strategies (sensor/actuator monitoring, control allocation, redundancy management) with an emphasis on safe degradation
Execute verification & validation activities, including SIL/HIL testing, Monte Carlo analysis, and support of flight-readiness reviews
Participate in flight-test planning and execution; analyze flight data, tune controllers, and iterate designs under supervision of senior technical leads
Collaborate in design reviews and code reviews; help uphold technical standards and best practices within the controls team
Qualification
Required
Education: Bachelor's degree in Engineering, Physics, Mathematics, or a related field
Experience: 4–7+ years designing and deploying flight control systems for fixed-wing aircraft or high-performance UAVs, including exposure to flight test
Strong understanding of flight dynamics, stability and controllability, and actuator/sensor modeling
Proficiency in C++ for embedded or real-time systems; strong MATLAB and/or Python skills for modeling, system identification, and analysis
Experience supporting verification workflows such as SIL/HIL testing, requirements validation, and safety-critical reviews
Familiarity with modern software development practices (git, code reviews, issue tracking) and telemetry/data analysis
Preferred
Experience with energy-based control concepts, autothrottle systems, sideslip/yaw coordination, or control allocation for over-actuated vehicles
Experience working with PX4 and ROS 2, or similar flight-control and robotics frameworks
Exposure to aerospace development standards (e.g., DO-178C, DO-331, ARP4754A) or equivalent safety-critical engineering rigor
Experience working on resource-constrained embedded systems with real-time performance considerations (latency, jitter, numerical robustness)
