About The Position

We’re raising the standard for what a medium-duty truck should be — delivering vehicles, infrastructure, and support designed to work for you. Fabricate prototype low-voltage and high-voltage wire harnesses for development vehicles, test vehicles, benches, and electrical systems. Build harnesses from electrical schematics, wiring tables, harness drawings, connector definitions, and engineering instructions. Cut, strip, crimp, splice, solder, seal, label, bundle, and protect wiring in accordance with engineering and workmanship requirements. Install prototype harnesses and electrical components into development vehicles. Perform electrical retrofits and wiring modifications on existing vehicles to support design changes, testing, troubleshooting, and vehicle upgrades. Remove and replace terminals, connectors, wiring, protection materials, and electrical components as required. Route and secure wiring to meet packaging, durability, serviceability, and safety requirements. Perform continuity, resistance, isolation, and point-to-point testing to verify completed harnesses and vehicle modifications. Troubleshoot open circuits, short circuits, terminal issues, incorrect pinouts, communication faults, and other vehicle electrical problems. Identify issues with drawings, parts, tooling, or installation instructions and provide feedback to engineering. Support prototype vehicle builds, engineering development activities, validation testing, and root-cause investigations. Maintain accurate records of vehicle modifications, harness revisions, deviations, and completed work. Work closely with wiring DREs, electrical engineers, vehicle technicians, manufacturing, and suppliers to resolve build and installation issues. Maintain harness-build tools, electrical test equipment, terminals, connectors, wire, and prototype materials. Follow established electrical-safety procedures, including high-voltage lockout and verification requirements when applicable.
