Senior Manufacturing Test Engineer - Power Electronics

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...
