We are seeking an Electrical Process Engineer to develop and improve manufacturing processes for electrical systems in commercial vehicles, including low-voltage (LV) and high-voltage (HV) systems. This role translates electrical designs into production-ready bills of materials (BOMs), drawings, work instructions, and inspection procedures.

The successful candidate will work closely with design engineering, production, and quality teams to ensure wiring harnesses and electrical components are built and installed correctly, resolve manufacturing issues, and support new products from prototype builds through production.

This list of essential duties is not all-inclusive and may be expanded to include other duties, as management may deem necessary from time to time. The team member must be able to perform each essential job duty identified below satisfactorily. Reasonable accommodations may be made to enable qualified individuals with disabilities to perform the essential duties of this position unless doing so would create an undue hardship.

• Develop and maintain electrical production BOMs, harness assembly drawings, installation drawings, and work instructions based on approved engineering designs.
• Define assembly sequences, wire routing, connector installation, fastening requirements, and inspection points for LV and HV systems.
• Establish requirements for production tools, crimping equipment, test fixtures, and electrical diagnostic equipment.
• Review electrical designs for manufacturability, installation access, serviceability, and error prevention.
• Coordinate engineering changes and ensure production documents reflect the correct revisions.

• Establish inspection criteria for in-house and supplier-built wiring harnesses, including wire gauge, length, identification, pin assignments, terminal crimps, connector assembly, and workmanship.
• Developpre-installation verification procedures to detect wiring errors before harnesses are installed in vehicles.
• Define and implement continuity, short-circuit, polarity, and other applicable electrical checks.
• Verify that installed wiring has appropriate routing, support, protection, clearance, and strain relief.
• Establish inspection requirements for HV cables and connections, including shielding, connector engagement, torque verification, and separation from other systems.
• Investigate recurring defects and implement corrective actions to reduce rework and improve assembly…
