Senior Manufacturing Test Engineer - Power ElectronicsWe 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 OwnYou 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 BringMust-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 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
Salary: $150,000 - $200,000+ base + meaningful equity
