Heron Power is a well-funded startup developing next-generation power conversion hardware (inverters and rectifiers) for renewables, energy storage, data centers, and grid applications. The company is led by veterans with extensive power electronics shipping experience and backed by top-tier investors.
As Senior Manufacturing Test Engineer, you will own the design and delivery of automated test infrastructure from the ground up, enabling the company to ship high-reliability, high-power systems at scale. This is a high-agency role with direct impact on company velocity.
Key responsibilities include:
- Design and architect complete automated test systems across the full product lifecycle: PCBA functional test (bed-of-nails, pogo, interface fixtures), subsystem validation, high-power/high-voltage end-of-line testing, and bi-directional converter test cells
- Own test architecture and coverage strategy from component 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 covering power cycling, efficiency mapping, transient response, fault injection, and protection validation
- Drive Design-for-Test (DFT) collaboration with hardware and firmware teams
- Own fixture design, instrumentation integration, automation software development (Python preferred), deployment, and long-term sustainment
- Continuously improve yield, debug speed, and test reliability in production
Required qualifications: 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 ownership of test systems from concept through deployment; hands-on expertise with instrumentation (oscilloscopes, power analyzers, electronic loads, DAQs, DMMs); strong Python experience for test automation or deep LabVIEW/TestStand experience with willingness to develop Python skills; solid fundamentals in circuits, power electronics, and high-voltage safety.
Nice-to-have experience includes bi-directional power testing, regenerative loads, PCBA manufacturing functional test and yield improvement, HIL systems, embedded firmware validation, and high-volume production test deployment.
