Better Trucks. Better World.

We’re raising the standard for what a medium-duty truck should be — delivering vehicles, infrastructure, and support designed to work for you.

About the Role

• 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
