Embedded Linux Engineer

The day-to-day

• Own the Linux platform: design, build, and maintain our embedded Linux distribution (Yocto Project) across our UAV compute boards — you are the owner of the whole Linux stack.
• Bring up hardware: bootloader (U-Boot), kernel configuration, device tree, and driver integration for new boards, sensors, and peripherals.
• Own the update strategy: design and maintain robust, fail-safe update mechanisms (A/B, atomic rollback) for OS, kernel, and firmware on deployed drones — ideally OTA.
• Integrate the flight stack: work alongside the PX4 flight controller and companion compute, wiring the Linux side into the wider system.
• Collaborate cross-team: work with hardware, avionics, and systems teams to ensure robust end-to-end UAV operation.
• Test in the field: support lab testing and live flight trials, including debugging and performance tuning on-site.
  
  

You should apply if you

• Experience: you bring 4+ years in embedded Linux development, ideally on UAV/robotics or other mission-critical platforms.
• Embedded Linux: you go deep — Yocto, bootloaders (U-Boot), the Linux kernel, device tree, and board bring-up are your home turf.
• Update strategy: you have designed robust update/OTA mechanisms (A/B, fail-safe rollback) for fielded devices.
• Languages: you are proficient in C and C++, and use Python for tooling.

• Systems: you understand real-time systems, communication protocols, and low-level Linux internals.
• Mindset: you thrive in a fast-paced, early-stage environment and are eligible for EU security clearance.
• Education: you hold a completed degree or equivalent training in a relevant field, e.g.:
• Computer science / software engineering
• Electrical / aerospace engineering
• Embedded systems / real-time computing
• Robotics / mechatronics
