About Sterling Technologies

The role

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.

What you will do

• 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.

What you need

• 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.
• Reliable attendance and a steady, quality‑first pace through a full shift.

Nice to have

• IPC/WHMA-A-620 certification (CIS or CIT), or willingness to earn it with us.
• Experience with heavy equipment, automotive, aerospace or military harnesses, including sealed connector systems and shielded or braided circuits.
• Ultrasonic splicing, overmolding or potting experience.
• Experience building first articles or prototypes from engineering prints.
• Familiarity with ISO 9001 / IATF 16949 quality systems and 5S.
• Lead or trainer experience on a harness line.

Work environment and physical requirements

• Stand or sit at a harness board for extended periods and perform repetitive hand assembly while holding quality.
• Lift up to 30 pounds occasionally, including harness boards, bins and finished assemblies.
• Use fine motor skills and hand‑eye coordination for small terminals and connector cavities.
• Distinguish wire colors accurately.
• Wear required PPE, including safety glasses.

Pay and benefits

• Pay: $22.00 to $25.00 per hour, based on experience.
• Health, dental and vision insurance
• 401(k)
• Paid time off
