Power Supply Test Engineer

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
