• Design, implement, and tune real-time flight-control algorithms (attitude, position, and trajectory loops) targeted at GNSS-denied missions.
• Develop high-rate state-estimation and sensor-fusion pipelines that blend IMU, barometer, optical flow, VIO, and SLAM data.
• Port and optimise these pipelines on flight computers (Jetson Orin, Raspberry Pi CM5, i.MX 8M plus) under real-time constraints.
• Extend and customise PX4 or write bare-metal control stacks where needed.
• Create Software-in-the-Loop (SITL) and Hardware-in-the-Loop (HITL) test environments; iterate rapidly between simulations and field flights.
• Instrument test vehicles, run flight campaigns, and mine logs to improve robustness in wind, vibration, and electromagnetic interference.

We are looking for

Required skills:

• Proficiency in C++14 and C99 (or newer).
• Proficiency in Linux environments.
• Hands-on experience with Linux SBCs such as Raspberry Pi, BeagleBone, or similar.

Nice to have:

• Previous experience with embedded systems, especially STM32 microcontrollers.
• Hands-on experience with PX4, ArduPilot, or custom flight-control firmware.
• Practical knowledge of RTK-GPS, UWB, or vision-based localization frameworks.

Additional skills that are advantageous

• Control theory — PID, LQR, observers, pole/zero placement, robustness analysis.
• Sensor fusion & estimation — Kalman variants, factor graphs, Bayesian filtering.
• Computer vision — feature tracking, optical flow, homography, depth estimation.
• Digital comms & electronics — UART, SPI, I²C, CAN-FD, logic-analyzer debugging.

What we offer

• Monthly gross salary €3,500-6,000 based on experience and impact
• Stock options
• A mission-driven team that values ownership, curiosity, and a hands-on approach to solving defense challenges
• Early technical influence in a growing defense tech startup
• A focus on outcomes
