5-7 years of experience in high-power testing setups for power converters
Proficient in conducting partial-discharge, hipot, and impulse tests at medium voltage
Experience designing reliability test plans and identifying root causes of failures
Ability to write clear test procedures for technicians and manufacturers
Familiarity with safety protocols around energized medium-voltage equipment and NFPA 70E qualifications
Bonus: Experience with certification testing (UL, IEC) and data acquisition automation (Python, LabVIEW)
Responsibilities
Build and enhance Fluidstack's SST test capabilities, including high-voltage insulation testing
Independently verify vendor and in-house SST hardware performance metrics
Conduct qualification and reliability campaigns to identify potential failures
Develop acceptance tests for production units and end-of-line testing procedures
Analyze test results to inform design decisions for architects and vendors
Benefits
Commitment to pay equity and transparency
Opportunity to work with cutting-edge technology in power conversion
Collaborative environment that values exceptional talent
Potential for professional growth and development in a specialized field
Full Job Description
Role Scope
Build Fluidstack's SST test capability, from a back-to-back full-power rig to high-voltage insulation testing, in-house or with a partner lab.
Verify vendor and in-house SST hardware independently: efficiency curves, temperature rise, partial discharge, and fault response at rated voltage and power.
Run qualification and reliability campaigns (thermal cycling, power cycling, humidity, accelerated life) that catch insulation and solder failures before the field does.
Write the acceptance tests every production unit must pass, and the end-of-line test each unit runs before it ships.
Turn test results into pass, fail, or redesign decisions written so the architect, the vendor, and leadership can act on them.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've built and run high-power test setups for power converters, including back-to-back or regenerative rigs at hundreds of kilowatts or more.
You've run partial-discharge, hipot, and impulse tests at medium voltage and interpreted the results yourself.
You've designed reliability test plans (HALT, thermal and power cycling) and traced failures to root cause.
You've written test procedures a technician or contract manufacturer can follow without you in the room.
You've worked around energized medium-voltage equipment, set the lab safety rules others followed, and hold current NFPA 70E qualified-person training.
Bonus: Certification testing (UL, IEC, witness testing with a test lab). Data acquisition and automation (Python, LabVIEW, NI hardware). Power analysis and fast current sensing (power analyzers, Rogowski coils). Electrical safety practice (NFPA 70E, arc flash). Manufacturing end-of-line test.
