Sterling Technologies has designed and built custom electrical and electromechanical assemblies for nearly five decades. From our Wixom, MI facility we produce wire harnesses, power distribution and control assemblies, control panels and printed circuit board assemblies for aerospace, military, medical, automotive, and on- and off-highway equipment makers, and we are a Tier 1 and Tier 2 supplier to the heavy equipment and automotive industries.

We are certified to ISO 9001 and IATF 16949, and we are growing. The shop is collaborative and team-oriented, and we hire people who want a long-term home, not a stopover. Learn more at

The Complex Wire Harness Builder builds our most involved harnesses: multi-branch, high-circuit-count assemblies for heavy equipment cabs, chassis and control systems. These harnesses often carry shielded and twisted-pair circuits, splices, braided or convoluted loom, and sealed connectors with dozens of cavities.

You work from harness drawings, wiring diagrams and work instructions on a layout board, build the harness end to end, test it, and sign off the paperwork before it ships. This is a hands-on production role for an experienced builder who can take a complex print and a kitted order and turn out a harness that passes the first time. You will also help newer builders and flag drawing or process problems to engineering.

• Build complex wire harnesses and cable assemblies to harness drawings, wiring diagrams, bills of materials and work instructions.
• Lay out, route and bundle wires on harness boards; set breakouts, branch lengths, splices, grommets, clips and strain relief to print dimensions.
• Cut, strip, crimp, solder and terminate wire from small‑gauge signal circuits to heavy‑gauge power cable; apply heat shrink, labels, braided sleeving, convoluted loom and tape wraps.
• Populate and seal connectors (Deutsch, TE/AMP, Aptiv, Molex, circular and similar), insert terminals to the correct cavity, and verify locks, seals and cavity plugs.
• Operate semi‑automatic equipment: crimp presses, wire strippers, wire twisters, ultrasonic splicers and heat‑shrink equipment; check crimp height and pull force on first pieces.
• Run continuity, insulation‑resistance and functional tests on test fixtures; troubleshoot and repair failures from the schematic.
• Inspect in‑process and finished harnesses to IPC/WHMA-A-620 and customer requirements; complete travelers, inspection records and quality paperwork.
• Build first articles and prototypes with engineering; recommend fixes to drawings, work instructions and board layouts.
• Coach newer harness builders and check their work when asked.
• Keep the work area clean and organized (5S) and follow all safety and PPE requirements.

• High school diploma or GED.
• 3+ years building wire harnesses or cable assemblies in a production setting, including multi‑branch harnesses built on a layout board.
• Reads and works from wiring diagrams, harness drawings, schematics, BOMs and work instructions without supervision.
• Skilled with hand and bench tools: strippers, hand and press crimpers, soldering irons, heat guns, pull testers, multimeters and continuity testers.
• Working knowledge of IPC/WHMA-A-620 requirements for crimps, solder joints, splices, strain relief and routing.
• Accurate wire color identification and the dexterity to work with fine‑gauge wire and small connector cavities.
