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.
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.
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
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
