Hardware Engineer, Power (DC/DC)

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

Minimum 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
