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 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 WHY JOIN HERON POWER? - Work on technically hard, high-impact problems in power electronics - High ownership and rapid learning curve - Direct influence on company velocity (your testers = faster iteration & shipping) - Competitive salary + meaningful equity in a well-funded company - Collaborative, first-principles culture with seasoned leaders Salary: $150,000 – $200,000+ base + meaningful equity
