Harness Engineer

You’ll be working with the Research and Development team

• This team runs on coffee with an infectious passion to build products that have never been built before. Our Flexible Energy Stack consists of the e^pack (battery pack), e^Port (charging connector), e^Plug (charging connector) and e^pump (charging station) which together unlock 15-minute rapid charging.
• Exponent’s philosophy: Break. Believe. Build.
• There’s no playbook for disruption. The only way to create a radical future is to continuously break, believe and build.
• Break assumptions and thumb rules.
• Believe in the process, the team, and through failures.

Build fast, passionately, and with first-principles thinking

• Key Responsibilities
• Key Responsibilities:
• Design wiring harnesses for Electric Vehicle, Battery and Charger applications.
• Perform cable selection based on current rating, voltage class, temperature, flexibility, and environmental conditions.
• Select appropriate crimp terminals, lugs, and connectors based on electrical, mechanical, and reliability requirements.
• Create 2D harness drawings, schematics, and BOMs.
• Define crimping specifications, wire routing, protection (conduits, tapes, grommets), and sealing strategies.
• Work closely with electrical, mechanical, and manufacturing teams to ensure design feasibility and ease of assembly.
• Validate designs through DFMEA, testing, and field feedback.
• Ensure compliance with automotive standards (ISO, AIS, LV, etc.) and safety requirements.
• Support prototype builds, troubleshooting, and root cause analysis of field issues.
• Required Skills:
• Strong understanding of electrical fundamentals (current carrying capacity, voltage drop, insulation, derating, etc.).
• Hands-on knowledge of cable types (PVC, XLPE, XLPO, shielded cables, high-voltage cables).
• Experience in crimp terminal selection, crimping processes, and failure modes.
• Good understanding of connector systems (automotive connectors, sealing classes, IP ratings).
• Ability to think from first principles rather than relying only on catalogs or legacy designs.
• Familiarity with wiring harness design tools (e.g., Rapid Harness, Solidworks).
• Experience with automotive or EV systems preferred.
