Job summary

Lumai Limited in the United Kingdom is seeking a Senior Embedded Engineer to build firmware, drivers and RTOS‑based control software for our AI accelerator, enabling reliable power-on and production operation.

You will lead BSP bring-up, develop Linux kernel drivers and collaborate with hardware engineers to validate bring‑up using JTAG, oscilloscopes and logic analyzers. Strong RTOS and debugging skills are essential.

Qualifications

• 5+ years of embedded software experience with C/C++ in production hardware products.
• Proven experience writing Linux device drivers (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: task scheduling, inter‑task communication, memory protection.
• Proficiency with hardware debugging tools: JTAG/SWD debuggers, oscilloscopes, logic analyzers.
• Bachelor's degree or higher in Electrical Engineering, Computer Engineering, or equivalent experience.

Responsibilities

• Develop and maintain device drivers for Lumai's 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: clock tree configuration, interrupt routing, peripheral initialisation.
• Implement RTOS-based control tasks using FreeRTOS or equivalent, ensuring deterministic scheduling and safe resource management.
• Work with hardware engineers to validate bring-up through JTAG debugging, oscilloscope analysis, and logic capture.
• Establish coding standards, review practices, and testing methodology for the embedded team.
