Firmware Engineer

Firmware Engineer Location: Mountain View, CA Industry: AI Hardware / Accelerators About the Role A fast-growing AI hardware company is looking for a Firmware Engineer to own the platform firmware that brings next-generation AI accelerator systems to life and keeps them secure, healthy, and observable. You’ll work across the firmware stack - from secure boot and hardware root of trust through embedded controllers/BMC and device firmware, as well as power management, telemetry, and the debug infrastructure required to operate accelerator platforms at scale. What You’ll Do Develop platform firmware across the stack, including boot ROM/bootloaders, embedded controllers/BMC, and device firmware for accelerator silicon and systems. Build secure boot and hardware root-of-trust functionality, including measured/verified boot, code signing, chain-of-trust, authenticated firmware updates, anti-rollback protections, and secure debug. Develop power-management firmware covering power sequencing, PMIC/voltage-rail control, DVFS, and thermal/power protection and budgeting. Build monitoring and telemetry infrastructure for sensors, system health, RAS, error logging, and platform-management/observability interfaces. Support board and post-silicon bring-up using JTAG, scan, and other hardware-debug infrastructure. Partner closely with silicon architecture, hardware/board, and software teams on firmware interfaces, threat modeling, and HW/SW co-design. Leverage modern development and assisted tooling to accelerate firmware development and code review. What We’re Looking For Strong C and assembly programming skills for embedded or firmware development.

Experience with bare-metal or RTOS environments on ARM or similar architectures. 5+ years of platform/system firmware development experience spanning areas such as boot, BMC/embedded controllers, and device firmware. Hands-on experience with secure boot, hardware root of trust, code signing, and secure/anti-rollback firmware updates. Experience developing power-management firmware, including power sequencing, PMICs/voltage regulators, DVFS, and thermal/power telemetry. Experience with platform monitoring and debugging, including sensors/telemetry, RAS/error handling, JTAG/debug, and management interfaces. Comfortable operating at the hardware/software boundary, including reading hardware datasheets and specifications, performing lab bring-up, and using equipment such as oscilloscopes and logic analyzers. Nice to Have Rust for firmware or embedded development. OpenBMC, UEFI, or coreboot. Accelerator, GPU, or server-platform firmware experience. Applied cryptography and key-management experience. Trusted Execution Environments such as ARM TrustZone. Familiarity with side-channel or fault-injection security concerns. Experience with standards such as NIST SP 800-193 or FIPS 140-3. Familiarity with SBOM and firmware supply-chain security.
