GNC Engineer-PX4 Flight Tuning

Redwire Corporation is a global space and defense technology company building the infrastructure of the future and delivering multi-domain solutions. 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.
• Competitive compensation.
• Health and children accident insurance, after probation time.
• Accident insurance from first day.
• Annual bonus program based on performance.
• Yearly salary review.
• Financial support in special life situations.
