## About the role

Own the platform firmware that brings our AI accelerator systems to life and keeps them secure, healthy, and observable — from secure boot and the hardware root of trust, through embedded-controller/BMC and device firmware, to power management, telemetry, and the debug infrastructure that keeps the platform running at scale.

## What they're looking for

- Strong C and assembly for embedded/firmware, bare-metal or RTOS on ARM (or similar)
- 5+ years developing platform/system firmware — boot, BMC/embedded controllers, and device firmware
- Hands-on with secure boot / hardware root of trust, code signing, and secure/anti-rollback update
- Power-management firmware — power sequencing, PMIC/voltage regulators, DVFS, and thermal/power telemetry
- Platform monitoring & debug — sensor/telemetry, RAS/error handling, JTAG/debug, and management interfaces
- Comfort at the HW/SW boundary — reading datasheets/specs, lab bring-up, scopes/logic analyzers
