We are looking for an electrical harness engineer who can play a key role in the development of our battery module electronics and control systems. You will be part of a rapidly growing team responsible for PCBA design, component selection, wire harness designs, and validation testing. Ideally, the harness engineer should have exposure to a broad range of technical challenges and methods in the context of product development, including connector selection, cable shielding, twisted pair communication wires, cable protection, and harness routing. Cross-team collaboration throughout the product development organization is a critical part of this role, so systems-level thinking and multidisciplinary engineering problem-solving are key traits of a successful candidate.

Responsibilities • Work cross-functionally with Mechanical, Compliance, and Electrical engineers to define harness requirements, material, and connector selection • Create and maintain 2D electrical harness single and multi-line schematics • Draft fabrication, manufacturing, inspection, and assembly drawings for wire harness assemblies • Identify suitable materials and components for wire harness assembly • Work closely with procurement teams to source materials and components from approved suppliers • Define routing, shielding, wire color, sealing, and EMI design specifications • Collaborate closely with mechanical engineers on wire harness CAD routing through mechanical features and harness fixation points • Troubleshoot wire harness bring-up and validation • Communicate project progress, challenges, and solutions effectively to team members and management
