## About the Role

Do you have experience in Machine learning?, Do you have a Bachelor's degree?, Must-Have

 * 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 debug tools: JTAG/SWD debuggers, oscilloscopes, logic analysers
 * Bachelor's degree or higher in Electrical Engineering, Computer Engineering, or equivalent experience

Strong Preference For

 * Experience with PCIe driver development or DMA engine programming
 * Familiarity with power management frameworks (ACPI, Linux PM runtime)
 * Prior work on AI accelerator or GPU driver development

## Description

Lumai's hardware needs software that runs reliably at the lowest levels of the stack. As our Senior Embedded Engineer, you will build the 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., * 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
