Hardware Engineer, Power (DC/DC)

Job description

Meta is seeking a Hardware Engineer specializing in DC-DC power conversion to join the team responsible for designing and validating MTIA module power solutions. In this role, you will contribute to the design of complex DC-DC power delivery systems for high-power ASICs while leading validation, characterization, and testing efforts to ensure designs meet performance, efficiency, and reliability requirements from prototype through production.

You will work closely with cross-functional teams including HW Platform and ASIC to define efficient power hardware, execute comprehensive validation plans, and provide feedback to improve power delivery designs. You will also partner with industry-leading vendors to qualify power solutions for next-generation high-power requirements.

Responsibilities

• Lead validation and characterization of DC-DC power conversion systems for high-power ASIC modules, including efficiency, transient response, thermal performance, and reliability testing
• Contribute to design of DC-DC power conversion solutions including topology selection, component selection, regulation schemes, and control loop design
• Develop and execute comprehensive power validation test plans covering hardware bring-up, functional verification, stress testing, and production qualification
• Participate in PDN design activities including power plane design, stack-up definition, and placement analysis for power delivery networks
• Execute hardware bring-up, debug, and troubleshooting of DC-DC power circuits using oscilloscopes, power analyzers, electronic loads, and other lab instrumentation
• Perform power integrity analysis using circuit modeling and simulation, closing the loop between simulation predictions and lab validation results
• Define test infrastructure and automation strategies for power delivery validation across multiple hardware generations
• Drive root cause analysis and failure investigation for power-related issues found during validation, qualification, or production
• Collaborate with ASIC and platform teams on power delivery specification requirements, balancing efficiency, thermal constraints, and space limitations
• Partner with external vendors to drive power solution design and qualify solutions through development milestones
• Develop and document validation methodologies, test procedures, and best practices for DC-DC power systems

Qualifications

6+ years of experience in power electronics validation or test engineering with a focus on DC-DC conversion for high-power digital systems Experience leading hardware bring-up, validation, and troubleshooting of DC-DC power circuits through production Experience with power validation instrumentation including oscilloscopes, power analyzers, electronic loads, and thermal measurement equipment Experience with power integrity analysis including correlation between simulation and lab measurements

Experience developing and executing validation test plans for power delivery systems covering efficiency, transient response, and reliability Experience with DC-DC topology selection, component selection, and control loop design Experience with thermal-electrical characterization and validation in space-constrained high-power applications Experience validating power solutions for high-power ASICs or accelerators exceeding 400W per device Experience with test automation and infrastructure development for power validation
