  • Measure and cut wire to required specifications.
  • Crimp connectors and terminals onto wires.
  • Perform light soldering of wire harnesses to PCB boards and other connectors.
  • Inspect and verify incoming materials before assembly.
  • Inspect completed cables and harnesses for accuracy and quality.

  • Use crimping tools, soldering tools, drills, and other hand and power tools.
  • Follow written, verbal, pictorial, and engineering drawing instructions.
  • Plan assembly work and maintain close attention to detail.
  • Follow established production and workmanship standards.
  • Work efficiently in a fast-paced manufacturing environment.

What We're Looking For

  • At least 1 year of related wire harness, cable assembly, or electro-mechanical assembly experience.
  • High school diploma or equivalent required; some college education preferred.
  • Ability to read and understand engineering drawings and Bills of Materials (BOMs).
  • Experience cutting wire and crimping connectors.
  • Ability to recognize good versus poor-quality crimps.
  • Experience with basic soldering is strongly preferred.
  • Familiarity with different types of hardware and electrical components.
  • Experience using hand tools, power tools, and crimpers.
  • Strong attention to detail and ability to follow precise instructions.
  • Ability to work effectively in a fast-paced production environment.

Benefits & Long-Term Opportunity

This position begins as a temp-to-hire role. After approximately six months of consistent performance, successful employees may have the opportunity to transition to a permanent position with a competitive compensation and benefits package that may include:

  • Medical insurance
  • Dental insurance
