Hardware Engineer, AI Accelerator Power Design

The ARD team designs accelerator reference platforms for Meta's AI hardware roadmap. This role owns the board-level power delivery system end to end for multi-kilowatt accelerator modules — DC/DC converter design and the PCB power delivery network, from topology and component selection through PDN architecture, stack-up, placement, layout, power integrity simulation, and lab correlation. You will work closely with ASIC, HW platform, thermal, SI/PI, and mechanical teams to co-design the power path, and directly with top-tier external partners and ODMs to drive designs from concept through production.

Responsibilities

• Own the module power delivery system end to end: DC/DC topology and component selection, regulation scheme, and the PCB power delivery network
• Set power specifications and efficiency targets for high-power ASIC loads; make component and architecture choices against space, thermal, cost, and production-reliability constraints
• Own PCB physical design of the power path: PDN architecture and optimization, power plane design, stack-up definition, placement analysis, and power circuit layout best practices
• Define and close power integrity targets through modeling and simulation (DC IR drop, AC impedance, transient response), and correlate simulation against lab measurements
• Partner with ASIC teams on package/board co-design, including socket and interposer power path, current density, and on-die vs. on-board decoupling allocation
• Lead board bring-up, validation, and debug of power rails; define measurement methodology for high-current, low-voltage rails
• Drive design reviews with ODM/CM partners; establish layout and DFx best practices adopted across the broader team
• Explore and develop leading-edge DC/DC and power delivery technologies (e.g., vertical power delivery, near-die power modules) with industry partners
• Contribute to design guidelines, review checklists, and tooling that raise the quality bar across ARD

Minimum Qualifications

• BS in Electrical Engineering or equivalent, plus 8+ years of hardware power design experience (MS + 6 years, or PhD + 4 years)
• Multiple complex power designs taken to volume production, with ownership of both the converter design and the board-level power delivery path
• DC/DC power electronics design experience: specification and requirement setting, topology and component selection, regulation scheme definition, and bring-up/validation/troubleshooting
• Demonstrated efficiency design practice in high-power systems: setting efficiency targets, component selection for efficiency, and trade-offs under space and thermal limitations
• Deep hands-on PCB physical design experience: PDN design and optimization, power plane design, stack-up definition, placement analysis, and power circuit layout best practices
• Power integrity expertise: circuit modeling and simulation used to drive design iteration, with proven simulation-to-lab closure, and knowledge of where/how to measure power effectively in DC/DC designs
• Experience with high-current, low-voltage rails and the decoupling/noise strategy for large digital loads (ASIC, SoC, GPU, or similar)
• Proficiency with schematic capture and layout tools, and PI/PDN simulation tools (e.g., Ansys SIwave/Q3D, Cadence Sigrity, or equivalent)
• Lab proficiency: oscilloscopes, electronic loads, thermal imaging, and measurement techniques appropriate to high-current power rails
• Track record operating independently on ambiguous problems and driving cross-functional efforts to resolution without guidance Experience supporting multiple complex programs in parallel, balancing competing schedules and priorities across concurrent design cycles
• Experience with thermal/mechanical co-design in dense liquid-cooled or air-cooled modules
• Experience with 1kW+ accelerator or ASIC-class power delivery, including 48V architectures
• Experience defining team-wide design standards, review processes, or automation
• Experience driving vendor and ODM development cycles end to end, including technology roadmap engagement with silicon and passive component suppliers
• Experience with vertical power delivery, power modules integrated near-die, or backside power delivery concepts
• Awareness of power delivery technology trends for 1kW-and-beyond ASICs
