## About the Role

* 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.

## Description

* 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., * 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.
