Heron Power is building cutting-edge power electronics for grid modernization, focusing on scalable inverters and rectifiers to connect large-scale renewables, storage, and loads. As Hardware Test Automation Engineer, you will architect and deliver complete automated test infrastructure spanning PCBA-level functional testing through end-of-line system validation and high-volume manufacturing test systems.
You will own the full lifecycle: defining test requirements and coverage strategy, architecting test solutions, designing fixtures and benches, developing automation software, deploying systems, and driving continuous improvement. Key responsibilities include designing bi-directional AC/DC and DC/DC converter testers capable of source and sink operation, specifying high-power test cells with grid simulators and protection systems, and implementing automated sequences for power cycling, efficiency mapping, and fault injection.
You will design PCBA functional fixtures (bed-of-nails, pogo boards), harness validation rigs, subsystem interface racks, and fault-injection systems. You'll specify and integrate instrumentation including power supplies, electronic loads, DAQs, oscilloscopes, power analyzers, and CAN/Ethernet tools. The role emphasizes rapid debug loops, yield improvement, test observability, and closing feedback loops with design and manufacturing teams.
Required: Bachelor's in Electrical Engineering, Computer Engineering, or Mechatronics (or equivalent); demonstrated experience designing and delivering automated test setups for high-voltage/high-power systems; strong circuits and instrumentation fundamentals; hands-on experience with scopes, DMMs, power supplies, electronic loads, DAQs, and digital interfaces (CAN, Ethernet, SPI, I2C, UART); proven ownership of a test system from concept through deployment and sustainment; cross-functional collaboration skills.
Nice-to-haves: bi-directional AC/DC or DC/DC power source experience; HIL development or embedded firmware validation infrastructure; PCBA manufacturing functional test and yield improvement; production traceability and calibration discipline; medium-voltage or high-power converter product test experience.
