• Design and develop complex wire harness systems using Zuken E3 and SOLIDWORKS.

• Create detailed harness schematics, harness architecture, and electrical interconnect documentation in Zuken E3.

• Develop 2D and 3D harness models, installation drawings, and manufacturing documentation.

• Define harness routing paths, breakout locations, branch points, and connector interfaces.

• Design mechanical retention solutions including clips, brackets, mounts, strain relief systems, and cable management features.

• Optimize harness layouts for manufacturability, serviceability, reliability, and cost.

Mechanical Integration & Packaging

• Route harnesses throughout battery pack assemblies, enclosures, sensors, and supporting subsystems.

• Perform packaging studies to ensure proper clearances, bend radius compliance, and environmental protection.

• Evaluate routing paths for vibration, abrasion, thermal exposure, and assembly accessibility.

• Collaborate with Mechanical Engineers to resolve packaging conflicts and integration challenges.

• Support sensor integration and electrical component mounting within complex assemblies.

Connector Selection & Electrical Integration

• Select connectors, terminals, backshells, cable protection systems, and sealing solutions.

• Design and integrate IP-rated connector systems for demanding operating environments.

• Interpret electrical schematics and convert electrical requirements into manufacturable harness designs.

• Partner with Electrical Engineers to ensure system-level electrical and mechanical compatibility.

• Support grounding, shielding, and high-reliability electrical interface requirements.

Documentation & Release

• Generate engineering drawings, wiring documentation, BOMs, and manufacturing packages.

• Create and maintain Zuken E3 harness documentation and release packages.

• Support engineering change orders (ECOs) and configuration management processes.

• Develop assembly instructions and manufacturing documentation for production teams.

• Ensure documentation accuracy throughout development, validation, and release cycles.

Prototype & Production Support

• Support prototype builds, pilot builds, and production launch activities.

• Troubleshoot harness-related issues during assembly, integration, and testing.

• Collaborate with manufacturing teams to improve assembly efficiency and quality.

• Participate in root cause investigations and corrective action implementation.

• Support design validation and production readiness efforts.

Required Qualifications

• Bachelor's degree in Mechanical Engineering or related engineering discipline.

• 5+ years of wire harness design experience in a production environment.

• Required experience with Zuken E3 for harness design, schematic development, and documentation.

• Strong SOLIDWORKS experience.

• Experience designing and releasing production wire harness assemblies.

• Expertise in mechanical harness routing, packaging, and integration.

• Experience selecting connectors and designing harness mounting and retention solutions.

• Knowledge of IP-rated connectors, sealed electrical interfaces, and environmental protection requirements.

• Ability to read and interpret electrical schematics and wiring diagrams.

• Experience creating manufacturing documentation, engineering drawings, and BOMs.

• Strong understanding of Design for Manufacturing (DFM) and Design for Assembly (DFA).
