Staff Integration and Validation Engineer-SF

About the Company

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.

Requirements

• ● BS or MS in Electrical or Computer Engineering.
• ● + 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.
• ● Nice to Have
• ● Familiarity with partial discharge, dielectric withstand, and insulation coordination against standards such as IEC 61800-5-1, UL 1741, or IEEE 1547.
• ● SiC or GaN device characterization, including double-pulse testing, switching loss measurement, and short-circuit behavior.
• ● EMC pre-compliance testing.
• ● Grounding and shielding design for fast-switching systems.
• ● HALT/HASS, accelerated life testing, or reliability engineering exposure.
• ● SF Pay Range 165,000 - 200,000 USD Pay Disclosure & Benefits
• ● Compensation will be determined based on experience, location, and other factors permitted by law.
• ● The benefits outlined below apply exclusively to employees located in the United States.
• ● Competitive Salary + Incentive Stock Options
• ● Medical, vision, and dental benefits for employees and their dependents, effective from the start of hire
