Heron Power•Scotts Valley, CA
•$150,000 - $200,000
About The Position
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.
Requirements
- 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 and architecture through deployment and sustainment
- Hands-on expertise with instrumentation (oscilloscopes, power analyzers, electronic loads, DAQs, DMMs)
- Strong Python experience for test automation (preferred) or deep experience with LabVIEW/TestStand + willingness to go deep on Python
- Solid fundamentals in circuits, power electronics, and high-voltage safety
Nice To Haves
- Experience with bi-directional power testing or regenerative loads
- PCBA manufacturing functional test and yield improvement
- HIL systems or embedded firmware validation
- High-volume production test deployment
Responsibilities
- 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)
- 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
Benefits
- Competitive salary + meaningful equity in a well-funded company
