Job Description
Must Have Technical/Functional Skills:
3+ years hands-on testing of high-voltage, high-power AC-DC / DC-DC converters
Strong understanding of PFC, flyback, LLC, or similar topologies
Proficient with oscilloscope, HV differential probes, current probes, power analyzers, electronic loads
Comfortable and safety-conscious working around high-energy DC buses
Roles & Responsibilities
Hands-on, bench-focused test engineer responsible for high-voltage power supply validation,
design characterization, and DVT execution for new product development programs.
Responsibilities
Perform extensive bench-level testing of high-voltage AC-DC and DC-DC power
supplies (300–800+ VDC bus)
Execute Design Characterization (DC) and DVT plans under full power and stress conditions
Validate efficiency, ripple, regulation, transient response, hold-up time, and protection features
Perform loop stability (FRA/Bode) measurements on high-voltage PFC and isolated stages
Conduct high-voltage start-up, inrush, and fault testing
Perform thermal characterization at full load and elevated ambient
Debug board-level and system-level issues in high-energy power circuits
Capture and analyze high-voltage waveforms using differential probes and current probes
Document structured test results with clear pass/fail criteria
Salary Range: $64,000 - $120,000 a year
