Staff Integration and Validation Engineer-SF

Role

Responsibilities

• Serve as the technical validation lead for an assigned SST subsystem, owning the validation strategy, plan, and schedule from initial design validation through production ramp and sustaining releases.
• Design, develop, and maintain test systems for high-voltage, high-current power electronics, including load banks, source/sink and back-to-back converter setups, and thermal chambers.
• Characterize and validate the electrical, thermal, and performance behavior of our products across prototype, pre-production, and production builds: efficiency and loss breakdown, switching behavior, gate drive integrity, insulation coordination, derating, and margin to limits.
• Own the regression suite for your subsystem so that every hardware revision and firmware release is held to the same bar and automate it so it runs continuously without hand-holding.
• Drive root cause analysis on failures and field escapes, from component-level debug through full-system interaction and follow fixes through to verified closure.
• Collaborate closely with hardware design, firmware, magnetics, mechanical, and systems teams from early architecture reviews onward, and push for design-for-test and design-for-validation features before layouts are frozen.
• Mentor engineers and technicians on high-voltage practice, measurement technique, and debug methodology. Review test plans and results across the team.
• Establish and uphold high-voltage safety practices in the lab, including interlocks, procedures, and training.
• Challenge ideas and decisions with reasoning from first principles.
• Travel to different facilities worldwide to collaborate with teams and deploy our solutions.

Qualifications

• BS or MS in Electrical or Computer Engineering.
• 6+ years of hands-on experience in test, validation, or integration engineering, with substantial time spent on power electronics.
• Demonstrated ownership of a product or subsystem through a full validation cycle, from first bring-up and design validation to production and sustaining regression.
• Deep understanding of power electronics principles: switching converter topologies, magnetics, gate drive, control loops, high-voltage and high-current systems, and power conversion technologies.
• Strong hands-on high-voltage lab skills and a rigorous, safety-first approach to working at power.
• Solid experience with PCBA schematics and debugging hardware down to the component level.
• Fluency with oscilloscopes, high-voltage differential probes, current shunts and Rogowski coils, power analyzers, multimeters, dielectric withstand testers, and thermal instrumentation such as thermocouples and IR imaging.
• Comfort with the data side of validation: structured results, dashboards, and statistical analysis that make a decision obvious.
• Be engaged, proactive, and positive when taking on challenging tasks, owning assignments, and taking accountability for personal and overall team success.
