Full 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
