Full Job Description
SENIOR MANUFACTURING TEST ENGINEER - POWER ELECTRONICS Heron Power is a well-funded startup building next-generation power conversion hardware for the 21st-century grid. Backed by top investors and led by veterans who have shipped gigawatts of power electronics, we are developing advanced converters (inverters & rectifiers) for renewables, energy storage, data centers, and grid applications. We are looking for a Manufacturing Test Engineer who will build from the ground up the automated test infrastructure that allows us to ship high-reliability, high-power systems at scale. WHAT YOU’LL OWN You will design, architect, and deliver complete automated test systems across the full lifecycle: - PCBA functional test (bed-of-nails, pogo, interface fixtures) - Subsystem validation - High-power / high-voltage end-of-line (EOL) testing - Bi-directional converter test cells (source + sink capability) Key Responsibilities - Own test architecture and coverage strategy from PCBA through full system - Design and build high-power test cells including bidirectional sources, regenerative loads, HV measurement chains, protection systems, and safety interlocks - Develop automated test sequences (power cycling, efficiency mapping, transient response, fault injection, protection validation) - Drive Design-for-Test (DFT) with hardware and firmware teams - Own fixture design, instrumentation integration, automation software (strong Python preferred), deployment, and long-term sustainment - Continuously improve yield, debug speed, and test reliability in a production environment This is a high-agency role. The test systems you build will directly determine how fast Heron can iterate, validate, and ship products. WHAT YOU BRING Must-Haves - Bachelor’s degree in Electrical Engineering (or equivalent practical experience) - Strong experience designing and delivering automated test systems for high-voltage / high-power electronics (inverters, converters, or similar) - Demonstrated end-to-end ow
