Electrical Integration Engineer

What we're building The marine industry supports recreation, global commerce, and national defense. And yet it runs on technology that hasn't meaningfully changed in fifty years. Until now. Arc is on a mission to electrify the marine industry. We're rethinking powertrains, software, and vessel designs from first principles. And we're already executing. We started with consumers to develop and harden our core technology. We're now scaling production of our flagship model with new models and sectors on the horizon. Now we're extending our platform to commercial applications, starting with tugs, ferries, and defense, with years worth of signed contracts and a pipeline that spans every vessel type on the water. The technology is proven, the momentum is building, and the opportunity is enormous. The marine industry is going electric and Arc is building the platform that powers it. Who we're looking for As Arc’s Electrical Integration Engineer, you will be solving production problems, improving processes, supporting technicians on the floor, and creating robust electrical systems that scale into volume manufacturing. You’ll thrive here if you move quickly, take ownership, communicate clearly, and enjoy turning complex problems into practical solutions. We're looking for someone fired up by the mission and ready to build. This is a full-time, on-site role at our Los Angeles headquarters. You'll report to the Manager of Electrical Engineering and work closely with Electrical Engineering, Manufacturing Engineering, Supply Chain, Quality, and Production teams. What you'll do Supporting diagnosis of issues through hands on electrical testing and over-the-air data acquisition, collaborating with software and controls engineers Supporting production teams daily by troubleshooting harnesses, electrical integration, and build issues on the manufacturing floor Driving root cause analysis and corrective actions for recurring production and field issues Driving constant improvement of full vehicle electrical system through manufacturing, design, validation, and process improvement Partnering with technicians and assemblers to optimize installation methods, routing paths, tooling, and work instructions Coordinating with outsourced harness suppliers on design intent, build quality, ECNs, first articles, and production readiness Supporting pilot builds, line launches, process validation, and production ramp activities Developing and improving test procedures for harness validation, continuity, hipot, and end-of-line verification Contributing to production documentation including build instructions, torque specs, inspection standards, and repair procedures Supporting vehicle electrical integration in a fast-paced production environment with urgency and high attention to detail Minimum Qualifications Experience in marine, automotive, or EV vehicle production environments Experience supporting production environments and resolving line-down or build-impacting issues quickly Experience interfacing with electrical schematics, formboards, drawings, and engineering change releases Hands-on experience building, reworking, or repairing harnesses Experience selecting connectors, terminals, crimps, seals, wire types, and tooling Familiarity with vehicle electrical systems and communication protocols (CAN, LIN, Ethernet, etc.) Strong troubleshooting skills using multimeters, scopes, and standard electrical tools Ability to work cross-functionally between engineering and production teams Experience with EMI/EMC mitigation in vehicles Clear written and verbal communication Bonus Qualifications Familiarity with ABYC, ISO, IPC/WHMA-A-620, UL, or IEC standards Experience in designing LV harness assemblies (Preferably Zuken E.3) Experience with HV cable assemblies, shielding, grounding, and safety systems Experience reducing cost through design simplification or supplier optimization Familiarity with CAD-to-formboard bridge tools (NX to Zuken Bridge) Experience wit
