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.Hardware Engineer, AI Accelerator Power Design Responsibilities:Own the module power delivery system end to end: DC/DC topology and component selection, regulation scheme, and the PCB power delivery networkSet power specifications and efficiency targets for high-power ASIC loadsmake component and architecture choices against space, thermal, cost, and production-reliability constraintsOwn PCB physical design of the power path: PDN architecture and optimization, power plane design, stack-up definition, placement analysis, and power circuit layout best practicesDefine and close power integrity targets through modeling and simulation (DC IR drop, AC impedance, transient response), and correlate simulation against lab measurementsPartner with ASIC teams on package/board co-design, including socket and interposer power path, current density, and on-die vs. on-board decoupling allocationLead board bring-up, validation, and debug of power railsdefine measurement methodology for high-current, low-voltage railsDrive design reviews with ODM/CM partnersestablish layout and DFx best practices adopted across the broader teamExplore and develop leading-edge DC/DC and power delivery technologies (e.g., vertical power delivery, near-die power modules) with industry partnersContribute to design guidelines, review checklists, and tooling that raise the quality bar across ARDMinimum 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 pathDC/DC power electronics design experience: specification and requirement setting, topology and component selection, regulation scheme definition, and bring-up/validation/troubleshootingDemonstrated efficiency design practice in high-power systems: setting efficiency targets, component selection for efficiency, and trade-offs under space and thermal limitationsDeep hands-on PCB physical design experience: PDN design and optimization, power plane design, stack-up definition, placement analysis, and power circuit layout best practicesPower 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 designsExperience 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 railsTrack record operating independently on ambiguous problems and driving cross-functional efforts to resolution without guidancePreferred Qualifications:Experience supporting multiple complex programs in parallel, balancing competing schedules and priorities across concurrent design cyclesExperience with thermal/mechanical co-design in dense liquid-cooled or air-cooled modulesExperience with 1kW+ accelerator or ASIC-class power delivery, including 48V architecturesExperience defining team-wide design standards, review processes, or automationExperience driving vendor and ODM development cycles end to end, including technology roadmap engagement with silicon and passive component suppliersExperience with vertical power delivery, power modules integrated near-die, or backside power delivery conceptsAwareness of power delivery technology trends for 1kW-and-beyond ASICsAbout Meta:Meta builds technologies that help people connect, find communities, and grow businesses.
