At Fractile, we’re building what we believe will be the world’s fastest AI inference chip from the ground up. We’re balanced across hardware and software engineering, and HW/SW co-design is how we work. We move fast, and we help each other move fast. We care about each other, the software we ship, and the people who rely on it.
We build the control chain that powers on, monitors, updates, and protects devices and racks across bare metal, RTOS, and embedded Linux. It’s production-critical software that keeps racks stable, updates safe, and hardware secure. It’s a critical layer in turning a tokens per second benchmark into a tokens per month system, turning great silicon into reliable output at rack scale.
You’ll be there for the first racks coming to life and rollout days where update safety matters. Your work makes the difference between a bad failure and a clean recovery path.
- Build systems software for board and rack management, from early bring-up through to production deployment.
- Implement the critical flows that keep fleets healthy: power-on and provisioning, monitoring/telemetry, updates, recovery, and security.
- Work closely with hardware and device software teams to define reliable interfaces, validate behaviour, and debug boundary issues.
- Proven experience shipping production-critical, reliable embedded systems across two or more of: bare metal, RTOS, embedded Linux (or deep expertise in one with clear ability to ramp the others).
- Strong C and/or Rust, and excellent engineering judgement around safety, testing, debugging, and failure modes.
- Comfortable working close to the hardware/software boundary (bootloaders/BSP/kernel-adjacent work) and collaborating tightly with HW, driver, and runtime teams.
- Computer Science, Electronic Engineering, Maths, Physics, or related degree and 3+ years of industry experience.
- OpenBMC experience and/or embedded Linux image build/customisation experience.
- Kernel device work (drivers, device tree, bring-up, perf/trace).
- Experience with GPUs or ML accelerators.
If you want to build the control software that keeps rack-scale systems stable, safe, and secure for next-gen AI, come build it together.
