Silicon Validation Firmware Engineer

Job description

Meta's Silicon Engineering team designs and delivers custom ASICs and SoCs that power products across Infrastructure, Reality Labs, and beyond. As a Silicon Validation Firmware Engineer at the senior level, you will develop and own firmware infrastructure used to validate custom silicon from pre-silicon emulation through post-silicon bring-up. You will work at the intersection of hardware and software, building low-level firmware, validation frameworks, and debug tooling that accelerate silicon readiness and ensure the reliability of Meta's custom chips at scale. Responsibilities: Develop and maintain low-level validation firmware in C/C++ targeting custom ASICs across emulation, FPGA, and silicon platforms - Lead pre-silicon and post-silicon validation efforts by authoring and executing firmware-driven test plans covering CPU subsystems, memory controllers, cache hierarchies, and high-speed interfaces - Bring up and debug complex SoC interfaces including PCIe, DDR, USB, and proprietary interconnects on emulation platforms and physical silicon - Build and maintain firmware infrastructure including bootloaders, hardware abstraction layers, and register-level drivers to support valid...
