• Integrate and calibrate IMUs, GPS/GNSS, magnetometers, barometers and vision-based sensors.
• Run SITL/HITL simulations to validate tuning and algorithms before hardware deployment.
• Support flight tests by preparing configurations, monitoring in-flight behaviour and troubleshooting issues.
• Diagnose anomalies from flight logs and telemetry and document tuning processes and validation results.

Required profile

• 3+ years of hands-on experience in GNC engineering, UAV flight control or autonomous systems.
• Bachelor's degree in aerospace engineering, robotics, control systems or a related field.
• Practical experience tuning multirotor, fixed-wing or VTOL platforms; hands-on flight-test experience.
• Strong analytical, problem-solving and documentation skills, and good English.

Required skills

• PX4 Autopilot, MAVLink, QGroundControl and flight-log analysis.
• Control theory, aircraft dynamics, sensor fusion and EKF-based state estimation.
• MATLAB/Simulink, Python and/or C++.
• Simulation tools such as ROS/ROS2, Gazebo, JMAVSim or AirSim.

What we offer

• Modern production facility with competitive compensation.
• Health and children accident insurance after probation, and accident insurance from day one.
