Electrical Integration Engineer; Harness Design

What we’re building

Every idea starts with a problem. Ours was simple:
Boats are special — but they’re loud, pollutant, unreliable, and stuck in the past. Gas-powered boats dominate not because they’re great, but because no better option has existed. Until now.

Arc is here to change that. We’re building 100% electric boats from the ground up — quicker, quieter, easier to maintain, and better for the water they ride on. We’re not just swapping gas for batteries. We’re rethinking every detail on the boat — from propulsion and powertrain to software and ownership model — applying first‑principles engineering from aerospace and EVs to deliver a better boating experience.

Electric boats haven’t taken over yet. The tech hasn’t been ready. The talent hasn’t been focused here. That’s our opportunity — and we’re moving fast.

We’re looking for someone who’s fired up by our mission and ready to build. You’ll thrive here if you adapt quickly, take ownership, and care about the details.

You will join our Electrical Integration Engineering team reporting to . You will work from our headquarters in Torrance, CA. Given that we’re a startup, you will be working in a fast‑moving, dynamic environment that requires adaptability. That said, here are some responsibilities and qualifications we expect to stay relatively constant for this role

• Support the Electrical Integration team by contributing to harness designs throughout the full product lifecycle, from initial concept through production release and implementation
• Specify wire gauges, shielding, connectors, and protective coverings based on electrical and environmental requirements
• Creation of harness schematic diagrams and 1:1 scale form boards
• Work closely with Mechanical Engineering team and other Electrical Integration team members to ensure mechanical fit requirements
• Contribute continuous improvement to current production harness designs
• Actively participate in both R&D and production environments
• Contribute to selection of LV and HV components, and placement in the vehicle through CAD
• Contribute to production environment work instructions related to created designs
• Support wire harness outsourcing efforts as consulted engineer

• 2-5 years experience with harness design process in Marine, Automotive, Aerospace, or similar
• Harness CAD routing experience (preferably in Siemens NX)
• Harness Schematic & Formboard creation (preferably in Zuken
  
  E.3)
• Experience with selection and qualification of wire harness crimp tooling
• Experience with wire harness testing and validation tools (Cirris)
• Experience with automotive communication protocols (CAN, LIN, Ethernet, etc)
• Experience with implementation of designs into production, both on‑site and through outsourcing partners
• Hands on experience in harness building
• Solid electrical fundamentals and electrical engineering knowledge
• Experience with High Voltage harnessing and cable design

• Experience with marine or automotive ABYC, ISO, or IEC standards
• Experience with EMI mitigation, both at component and system integration level
• Experience in PCB design, using schematic capture and layout tools
• Familiar with CAD to Formboard bridging tools (NX to Zuken Bridge)
• Experience in Design Failure Modes and Effects Analysis (DFMEA) process
• Ability to articulate and defend engineering decisions
• Clear written and verbal communication
• Strong time management skills
• Comfortable pushing at a fast but sustainable pace

At Arc, we encourage diversity and consider all qualified applicants equally for employment, regardless of background, identity, or status. You’re always welcome to reach out even if you don’t meet many of these qualifications. Passion and aptitude make up for a lot.

We move with urgency and build with care. We value these five things above all else:

• Ownership over both your work and the company’s success
• Empathy for colleagues and for customers
• Humility in problem solving and collaboration
• Pragmatism for navigating ambiguity quickly and sensibly
• Inclusion of different backgrounds, opinions, cultures, and perspectives.

We want people who share and embody these values. It…
