Senior Embedded / Firmware Engineer - Robotics & Physical AI - £170k

Lumyn are working with a small number of UK-based robotics and physical AI companies in the defence tech, drone autonomy, industrial robotics space, all sub-50 staff and recently funded.

We are looking for senior embedded / firmware engineers to join at the founding-tier equity level to spearhead the embedded engineering work end-to-end from day one - firmware, hardware integration and on-device autonomy alongside the founding team, with real ownership of the technical stack.

Requirements:

• 5+ years senior embedded or firmware experience (STM32, FreeRTOS, bare metal C/C++, or embedded Linux on Jetson-class compute)
• Strong systems background - sensor integration, real-time control, motor control, autonomy stack, or comms
• UK-based or willing to relocate to UK; British / EU / EEA citizenship for defence-cleared roles
• Comfortable working at sub-50-staff founding teams with meaningful equity

If you are a senior engineer with physical AI, robotics or defence experience that match the above, I would love to speak with you around a few of the open positions we have here at Lumyn.
