Senior Embedded Linux Engineer

Salary: £59,000 - 99,000 per year

• 5+ years of embedded software experience with C/C++ in production hardware products
• Proven experience writing Linux device drivers, including character, platform, or PCIe drivers
• Hands-on BSP bring-up experience on custom hardware, from schematic review to first OS boot
• Solid understanding of RTOS concepts, including task scheduling, inter-task communication, and memory protection
• Proficiency with hardware debug tools, including JTAG/SWD debuggers, oscilloscopes, and logic analysers

• Develop and maintain device drivers for our AI accelerator, targeting Linux kernel and bare-metal environments
• Write and debug firmware for control and management processors alongside the main accelerator die
• Lead BSP bring-up for new hardware revisions, including clock tree configuration, interrupt routing, and peripheral initialisation
• Implement RTOS-based control tasks using FreeRTOS or an equivalent RTOS, ensuring deterministic scheduling and safe resource management
• Work with hardware engineers to validate bring-up through JTAG debugging, oscilloscope analysis, and logic capture

More:

We are a successful, venture-backed UK startup founded in 2022, pioneering a breakthrough AI accelerator for data centers using 3D optical compute. We have already secured over £15 million in investment and are scaling rapidly to deploy the fastest optical compute currently available globally. The role focuses on building firmware, drivers, and RTOS-based control software that bring our AI accelerator to life, from initial power-on through to stable, performant operation in production systems.

Our interview process has four stages and we aim to move quickly, with an expected timeline of around three to four weeks end to end.
