Job summary

Heron Power Inc. is seeking a Hardware Test Automation Engineer - Power Electronics to build automated test cells and a scalable test infrastructure.

You will integrate power hardware, instrumentation, control software, and data pipelines to enable reliable production and engineering tools, covering PCBA to system and EOL testing. You will own the lifecycle from test requirements through deployment and continuous improvement, partnering with design, manufacturing, and reliability teams to

Qualifications

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Mechatronics, or equivalent practical experience.
• Experience designing and delivering automated test setups for high-voltage / high-power systems.
• Strong fundamentals in circuits and instrumentation.
• Hands-on experience with scopes, DMMs, power supplies, electronic loads, DAQs, and digital interfaces (CAN, Ethernet, SPI, I2C, UART).
• Demonstrated ownership of a test system from concept through deployment and sustainment.
• Ability to work cross-functionally and drive issues to closure.

Responsibilities

• Define functional test coverage for PCBAs, subsystems, and full systems.
• Architect test solutions balancing coverage, cycle time, cost, and maintainability.
• Partner with design engineering to drive Design-for-Test (DFT): test points, boundary scan, firmware testing, and observability.
• Define regression strategy to prevent re-learning the same lessons across builds and firmware releases.
• Establish pass/fail criteria grounded in real system performance and reliability goals.
• Design and deliver automated bi-directional converter testers for AC/DC and DC/DC systems capable of source and sink operation.
• Architect high-power test cells including bidirectional AC/DC sources, regenerative loads, grid simulators, HV measurement chains, interlocks and safe operating procedures.
• Implement automated test sequences for power cycling, efficiency mapping, transient response, fault injection, protection validation.
• Ensure high-voltage testing is safe, repeatable, and production-ready.
• Design and build PCBA functional fixtures, harnesses, interface racks, and fault-injection rigs.
• Specify and integrate instrumentation including power supplies, electronic loads, DAQs, DMMs, oscilloscopes, power analyzers, CAN/Ethernet/RS-485 tools, and sensors.
• Deliver stations that are robust, safe, maintainable, and scalable.
• Drive rapid debug loops when tests fail.
• Improve test observability and diagnostic resolution.
• Own station version control, calibration, uptime, and software releases.
• Partner with manufacturing to improve yield, reduce escapes, and accelerate learning loops.
• Close the loop with design and reliability teams.
• You will build the automated tester capability from the ground up.
• Real breadth: PCBA functional → engineering validation → high-power HIL → end-of-line testing → production.
• Direct ownership of high-voltage, high-energy automated test systems.
• High agency and high slope - the testers you build directly determine how fast we can iterate and ship.
