Redwire Defense Tech specializes in the design, manufacturing, and integration of autonomous unmanned aerial vehicles (UAVs) and advanced electro-optical surveillance systems. Our technologies are trusted and deployed across defense, security, civil, and industrial sectors worldwide. We are seeking a highly skilled Guidance, Navigation & Control (GNC) Engineer with strong experience in PX4 flight control systems to join our UAV development team. Key Responsibilities: Perform advanced PX4 firmware tuning for attitude, rate, and position controllers to optimize UAV performance across different aircraft types. Conduct detailed flight performance evaluations, analyse log data, and implement tuning improvements for stability, responsiveness, and mission requirements. Develop, refine, and validate GNC algorithms for navigation, control, and autonomous flight behaviours. Integrate and calibrate sensors including IMUs, GPS/GNSS, magnetometers, barometers, and vision-based systems. Execute SITL/HITL simulations to validate tuning and control algorithms before deployment to hardware. Support flight-tests operations by preparing tuning configurations, monitoring in-flight behaviour, and troubleshooting issues. Diagnose anomalies using flight logs and system telemetry, implementing robust fixes and improvements. Contribute to PX4 firmware enhancements by modifying or adding modules when required for performance or functionality. Document tuning processes, control logic, system behaviour, and validation results for engineering and production teams. Qualifications: 3+ years of hands-on experience in GNC engineering, UAV flight control, or autonomous systems development. Extensive experience with PX4 Autopilot , MAVLink, QGroundControl, and comprehensive flight-log analysis. Strong understanding of control theory , aircraft dynamics, sensor fusion, and EKF-based state estimation. Proficient with MATLAB/Simulink , Python, and/or C++ for modelling, tuning, and algorithm development. Practical experience tuning multirotor, fixed wing, or VTOL platforms for real-world operational environments. Skilled with simulation tools such as ROS/ROS2, Gazebo, JMAVSim, or AirSim for GNC testing and validation. Hands-on experience participating in UAV flight tests, diagnosing issues, and iteratively improving system behaviour. Strong analytical, problem-solving, and documentation skills suited for high-reliability UAV production environments. Good spoken and written English communication skills. Bachelor’s in aerospace engineering, robotics, control systems, or related field. We offer: Modern production facility with cutting-edge equipment and a dynamic work environment.
