Arc is electrifying the marine industry by rethinking powertrains, software, and vessel designs from first principles. The company has proven core technology, is scaling production of its flagship recreational model, and is now extending its platform to commercial applications (tugs, ferries, defense) with signed contracts and a strong pipeline.
In this role, you will own major boat systems from specification through design, prototyping, validation, and high-volume manufacturing. Responsibilities include:
• Designing and releasing hardware across the full boat: composite structures (hull, deck, stringer, hatches, hardtop with Class A surfacing), interiors and mechanisms (upholstery, tower, windshield, storage), and marine systems (ballast, bilge, steering, cooling, surf tabs)
• Defining system requirements and leading design reviews, making tradeoffs across performance, weight, cost, and manufacturability
• Leading prototyping through on-water testing, root-causing failures, and driving fixes into production
• Integrating with battery, powertrain, electrical, and controls teams on packaging and interfaces
• Partnering with industrial design, suppliers, and manufacturing on design-for-manufacturability and next-generation products
• Mentoring engineers and setting the technical bar for the team
• Working hands-on in production or traveling to suppliers as needed
You will report to the Lead Mechanical Engineer and work closely with a lean, high-trust team where everyone's work matters. This is a full-time, on-site role at Arc's Los Angeles headquarters.
