Firmware Engineer

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 You'll Do

• Platform firmware — develop firmware across the stack: boot ROM/bootloaders, embedded controllers / BMC, and device firmware for our accelerator silicon and systems

• Secure boot & root of trust — measured/verified boot, code signing and chain-of-trust, authenticated firmware update (anti-rollback), and secure debug

• Power management — power sequencing, PMIC/voltage-rail control, DVFS, and power/thermal protection and budgeting

• Monitoring & telemetry — sensors, health/RAS, error logging, and platform management/observability interfaces

• Debug & bring-up — JTAG/scan and debug infrastructure; board and post-silicon bring-up

• Partner with silicon/architecture, hardware/board, and software teams on firmware interfaces, threat modeling, and HW/SW co-design

• Assisted tool flows to accelerate development and review

What We'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

• (Optional) Rust for firmware/embedded development; OpenBMC, UEFI/coreboot; accelerator/GPU/server firmware; applied crypto & key management; TEE (TrustZone); side-channel/fault-injection awareness; standards (NIST SP 800-193, FIPS 140-3); SBOM/supply-chain security

Compensation

Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO.
