Job description

Job Title:
Testing Technologist - Electrical/Electronics

Position Description:
Client is seeking a highly skilled and motivated Inverter Testing Technologist to support the development of current and next‑generation electrified vehicle traction inverters at the Power Electronics Laboratory in Allen Park, MI. In this dynamic, hands‑on role, you will act as a key electromechanical builder‑fabricating custom structural test stands and constructing complex physical test setups from engineering drawings and schematics. You will inspect critical inverter components (capacitors, power modules, and busbars), assemble prototype test samples, instrument them with diagnostic sensors, and build custom low‑voltage and high‑voltage wiring harnesses. Beyond the initial build, you will configure and operate advanced laboratory equipment‑including high‑voltage testers, thermal chambers, and power cyclers‑while troubleshooting experimental setups, performing routine equipment maintenance, and executing safe, systematic teardowns. Additionally, you will support day‑to‑day lab operations through inventory management, shipping and receiving, equipment calibration, and maintaining a safe, highly organized facility.

Skills Required:
Test Setup, Repair & Teardown Diagnostics & Schematics Mechanical Fabrication & Test Stands Harness Fabrication & Electronics

Experience Required:
3+ years of experience working in an R&D, validation, or test laboratory, with a proven track record of building, maintaining, and systematically tearing down complex electromechanical test setups.
2+ years of experience in Low Voltage (LV) and High Voltage (HV) wiring harness fabrication, assembly, and quality inspection.
Demonstrated experience in manual machining, custom prototyping, and fabricating test fixtures, mounts, or structural framing from CAD models, engineering drawings, or hand sketches.
Proven experience reading, interpreting, and troubleshooting from both electrical schematics and mechanical assembly drawings.
Strong working knowledge of high-voltage systems (208VAC-480VAC & 50VDC-1000VDC) and standard laboratory safety protocols, including ECPL (Energy Control / Power Lock‑out) or LOTO.

Experience Preferred:
Experience with 3D printing and rapid prototyping.
Metrology & Blueprint Reading: Highly skilled in reading GD&T guidelines and using precision measuring tools (calipers, micrometers, dial indicators) to inspect finished parts.
Experience with through‑hole and surface‑mount (SMT) PCB soldering

Education Required:
High School Diploma / GED

Education Preferred:
Associate's degree in automotive technology, or equivalent practical experience in a mechanical, electrical, automotive, or related technical field.
