Core Responsibilities

Primary Functions

Accurately read, interpret, and work from complex technical documents including engineering drawings, wiring diagrams, schematics, and bills of material (BOMs).
Select, measure, and precisely cut wires and cables to specified lengths using both manual and automated equipment.
Carefully strip wire insulation without nicking or damaging conductors, preparing them for termination.
Perform high-quality crimping of various terminals and contacts onto wires using a wide range of hand tools and pneumatic crimpers.
Execute proficient soldering of wires to connectors, circuit boards, and other components, often adhering to IPC J-STD-001 standards.
Assemble connectors, backshells, and other hardware onto cables, ensuring proper alignment, keying, and torque specifications are met.
Route and bundle wires into a harness assembly according to detailed layout drawings, using techniques like lacing cord, zip ties, and various types of sleeving.
Install and position assembled harnesses into final assemblies, panels, or chassis, ensuring proper routing and clearance.
Operate electronic testing equipment, such as multimeters and specialized cable testers, to verify continuity, insulation resistance, and proper pin-to-pin wiring.
Conduct thorough in-process and final visual inspections to identify any defects, such as improper crimps, cold solder joints, or incorrect wire routing, ensuring 100% quality.
Troubleshoot and diagnose faults in new and existing harnesses, performing necessary repairs, re-work, and modifications as required.
Apply potting, encapsulation compounds, or heat-shrink tubing to protect connections from moisture, vibration, and environmental factors.
Maintain meticulous records of work performed, including completing production travelers, logging test results, and documenting any deviations from the standard process.
Use precision measuring tools like calipers and micrometers to verify component dimensions and assembly tolerances.
Manage inventory of components for assigned jobs, ensuring all necessary parts are available and reporting any shortages to a supervisor or materials handler.
Adhere strictly to all safety protocols and workplace procedures, including the proper use of Personal Protective Equipment (PPE) and ESD (Electrostatic Discharge) prevention practices.
Maintain a clean, organized, and efficient workspace following 5S or similar lean manufacturing principles.
Collaborate with manufacturing engineers and designers to provide feedback on the manufacturability of new harness designs and suggest potential improvements.
Build and assemble first-article and prototype harnesses, working closely with engineering to validate new designs and assembly processes.
Set up and calibrate assembly tools and equipment, ensuring they are functioning correctly and within specified parameters before use.

Secondary Functions

Assist engineering teams with the development of prototype assemblies, offering practical feedback on manufacturability and potential process improvements.
Contribute to continuous improvement initiatives by identifying and suggesting enhancements to assembly processes, tooling, or workplace organization to boost quality and efficiency.
Collaborate closely with the Quality Assurance department to understand inspection criteria, resolve non-conformance issues, and ensure all products meet or exceed industry standards.
Participate actively in team meetings, safety briefings, and ongoing training programs to stay current on new products, techniques, and company policies.
