ELECTRICAL WIRE HARNESS ENGINEER

BERKELEY, CA 94710

DURATION: Contract to Hire

Role Description:

We are looking for an electrical wire harness engineer who can play a key role in the development of 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.

What you'll do:

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

What you'll bring:

A Bachelor of Science Degree in Mechanical OR Electrical Engineering

2 years' experience in product development (experience in energy storage or renewable energy is a plus)

Hands-on experience designing and building electro-mechanical systems and harnesses

Expertise with 3D CAD, PLM, and Harness design software

Proven expertise in 2D drawing creation software

Strong knowledge of industry-specific regulations and standards (e.g., UL, IPC)

Familiarity with reading electrical schematics

Experience with twisted pair and shielding for communication harnesses

Experience working with weather-sealed connector
