Firmware Engineer - Platform & Board Management

What MatX Is Building

MatX's mission is to make the world’s best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability. MatX is seeking System Software Engineer to join our team as we create best-in-class silicon for high-performance and sustainable GenAI. Successful candidates for these roles will be responsible for delivering performant and functionally accurate silicon for MatX products across compute, memory management. High-speed connectivity and other key technologies.

The MatX host system software team owns everything that makes our AI silicon and systems usable: from Linux kernel drivers up through node and cluster management. We build integrated AI systems from custom silicon through fully deployed rack-scale infrastructure. Our firmware runs closest to the hardware: it brings boards to life, keeps them healthy in production, and gives the rest of the stack a trustworthy view of the platform.

What you'll do

- Develop and extend board management firmware built on open-source firmware stacks

- Enhance and maintain embedded firmware running on ARM microcontrollers, including code delivered by silicon partners

- Own platform capabilities end to end: sensor monitoring, power and thermal management, firmware update, and hardware health reporting

- Participate in board bring-up alongside hardware and system software teams, from first power-on through production

- Debug across the firmware/hardware boundary using lab equipment and low-level tooling

What we're looking for

- Strong embedded C development experience on ARM-based microcontrollers

- Experience with real-time or bare-metal firmware: interrupts, timing constraints, and working within tight memory budget

- Direct experience working with embedded firmware with a hyperscaler/datacenter.

- Hands-on familiarity with board-level buses and management interfaces

- Experience working within large existing firmware codebases — extending, integrating, and maintaining code you didn't originate

- Comfort in a lab: schematics, scopes, and hardware that doesn't behave the way the documentation says

- Ability to collaborate closely with hardware, silicon, and system software engineers

Nice to have

- Experience with Linux-based board management controller firmware and its build systems

- Familiarity with server platform management standards and protocols

- Exposure to firmware security: secure boot, signed updates, attestation

- Prior involvement in open-source firmware communities
