Job summary

Meta in Fremont, CA is seeking an AI Accelerator Module Design Engineer to own the electrical and PCB design for high-power accelerator modules, integrating MTIA and third‑party accelerators. You will co-design packaging, route breakout traces, and optimize power delivery while ensuring client-wide standards are met.

You will collaborate with ASIC, platform, and rack teams to deliver robust module designs, lead bring-up efforts, and push cross‑domain refinements in a fast-paced environment.

Qualifications

• BS in Electrical Engineering, Computer Engineering, or related technical discipline.
• 6+ years of experience in electrical and PCB design for high-speed, high-power digital systems.
• Experience taking at least one complex custom board or module design from concept through volume production.
• Proficiency with EDA tools for schematic capture and PCB design (Cadence Allegro/OrCAD, Altium Designer, or equivalent).
• Experience with high-speed digital interface design (PCIe, CXL, DDR4/DDR5, HBM, Ethernet 25G+) and SerDes-based channel design.
• Experience with power delivery network design for high-current loads, including DC-DC topology selection and decoupling strategy.
• Experience with board bring-up, debug, and failure analysis using oscilloscopes, VNAs, TDR, and power analyzers.
• Experience communicating technical trade-offs clearly in writing and verbally.

Responsibilities

• Own the electrical design and PCB implementation of AI accelerator modules for high-power custom silicon and third-party accelerators.
• Contribute to module requirements and specifications with ASIC, platform, rack, and systems teams.
• Execute ASIC package-to-board co-design, breakout routing, substrate interaction, and escape feasibility for high-pin-count devices.
• Design power delivery networks for high-current loads and plan plane/stackup partitioning.
• Implement high-speed interface design across PCIe Gen5/Gen6, CXL, DDR5/LPDDR, HBM, and Ethernet up to 800G.
• Lead SI/PI analysis and drive design fixes through bring-up, debugging, and cross-functional reviews.
• Collaborate with ODM/JDM partners through NPI-to-mass-production cycles and contribute to reusable reference designs.

Job description

The Hardware Design, Rack-scale Technology and Platforms (HDRTP) engineering team designs, develops, validates, and delivers the hardware platforms that power Meta's AI and HPC infrastructure, deployed in data centers worldwide. Our designs are published for industry adoption through the Open Compute Project Foundation. We are seeking an AI Accelerator Module Design Engineer to own the electrical and PCB design of accelerator modules supporting Meta's custom silicon (MTIA) and third-party AI accelerators. You will own module-level electrical design end to end from requirements and ASIC package-to-board co-design through schematic, stackup, power delivery, bring-up, and volume production on one or more programs. You will work within established design methodologies and reference architectures, and contribute improvements to them. You will drive cross-domain trade-offs between signal integrity, power integrity, thermal, mechanical, and cost, partnering with senior engineers and architects on the most ambiguous decisions. You will operate independently on your program's scope in a fast-moving environment.Hardware Engineer, AI Accelerator Module Design Responsibilities:Own the electrical design and PCB implementation of AI accelerator modules for high-performance, high-power custom silicon (MTIA) and third-party acceleratorsContribute to module requirements and specifications in partnership with ASIC, platform, rack, and systems architecture teamsExecute ASIC package-to-board co-design, including breakout routing, substrate interaction, and escape feasibility analysis for high pin-count devicesDesign power delivery networks for high-current loads, including DC-DC topology selection, decoupling strategy, and plane/stackup partitioningImplement high-speed interface design across PCIe Gen5/Gen6, CXL, DDR5/LPDDR, HBM, and Ethernet up to 800G, including simulation-guided stackup and channel budgetingPartner with Signal and Power Integrity teams on SI/PI analysis and simulation-to-measurement correlation for your designsParticipate in and prepare module-level design reviewsensure schematic, layout, and DFM/DFT readiness for your designsLead board bring-up and debugroot-cause electrical, power, and interoperability failures and drive design fixes to closureWork with ODM/JDM partners through NPI-to-mass-production cycles, holding partners to Meta design standards and scheduleContribute to reusable reference designs, design-rule libraries, and design automationsupport publication through the Open Compute ProjectEvaluate emerging technologies with industry partners – HDI and advanced substrates, embedded components, novel materialsCollaborate across hardware, firmware, mechanical, thermal, and manufacturing teams to resolve cross-functional issuesShare knowledge and help onboard other PCB/module design engineersMinimum Qualifications:BS in Electrical Engineering, Computer Engineering, or a related technical discipline6+ years of experience in electrical and PCB design for high-speed, high-power digital systems (servers, accelerators, networking, or HPC)Experience taking at least one complex custom board or module design from concept through volume productionProficiency with EDA tools for schematic capture and PCB design (Cadence Allegro/OrCAD, Altium Designer, or equivalent)Experience with high-speed digital interface design (PCIe, CXL, DDR4/DDR5, HBM, Ethernet 25G+) and SerDes-based channel designExperience with power delivery network design for high-current loads, including DC-DC topology selection and decoupling strategyExperience with board bring-up, debug, and failure analysis using oscilloscopes, VNAs, TDR, and power analyzersExperience communicating technical trade-offs clearly in writing and verballyPreferred Qualifications:8+ years of experience in module or board design for AI/ML accelerators, data center, or HPC hardwareMS in Electrical Engineering with emphasis on electromagnetics, signal integrity, or power electronicsScripting or design-automation experience (Python, SKILL/LISP, or equivalent)Experience collaborating across hardware, firmware, mechanical, thermal, and manufacturing teamsExposure to ASIC or GPU package-to-board co-design and breakout routing for high pin-count devicesContributions to open-source hardware or the Open Compute Project, or external technical publicationsExperience with liquid-cooled or thermally-constrained module designHands-on experience with SI/PI simulation tools (Ansys HFSS, Cadence Sigrity, Keysight ADS/PathWave, or equivalent)Experience with HDI, rigid-flex, embedded component, or advanced substrate technologiesExperience designing accelerator modules for custom in-house siliconExperience working with external ODM/JDM or component partnersExperience with next-generation interconnect: PCIe Gen6, CXL 3.x, UCIe, scale-up fabrics, or co-packaged opticsAbout Meta:Meta builds technologies that help people connect, find communities, and grow businesses.
