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 (as needed), HV measurement chains, contactors and protection systems, interlocks and safe operating procedures, grounding strategy
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 (bed-of-nails, pogo, interface boards), harness and connector validation fixtures, subsystem and system-level 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
Qualification
Required
Bachelor's degree in Electrical Engineering, Computer Engineering, Mechatronics, or equivalent practical experience
Experience in 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
Preferred
Experience with bi-directional AC/DC or DC/DC power sources and regenerative loads
Experience with HIL development or embedded firmware validation infrastructure
Experience with PCBA manufacturing functional test and yield improvement
Familiarity with production traceability systems and calibration discipline
Experience developing test systems for medium-voltage or high-power converter products
