Senior CAD Designer

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

As Arc's Senior CAD Designer, you will own the CAD backbone of our vessels — the models, the drawing packages, and the standards the rest of Engineering builds against. That means producing production-intent CAD for hull structures, mechanical systems, and powertrain integration; releasing drawing packages a vendor can quote without a phone call; and setting the CAD standards that keep a fast-growing team building off the same source of truth.

We're looking for someone fired up by the mission and ready to build. You'll thrive here if you move fast, take ownership, and care about the details.

• Creating production-intent CAD for hull and deck structures, mechanical systems, and powertrain interfaces
• Releasing fully dimensioned drawing packages to manufacturing and suppliers, applying GD&T per ASME Y14.5 and running tolerance stack-ups on critical interfaces
• Owning large assemblies and the Teamcenter/PLM structure, including setting up the eBOM configuration and assembly architecture for a clean, scalable engineering data model
• Setting Engineering's CAD standards, templates, naming conventions, and revision control
• Owning the boat-level eBOM and mass properties
• Partnering with manufacturing and supply chain on DFM to catch problems while they're still pixels
• Supporting prototype builds on the floor and fold what you learn back into the models

• Bachelor’s degree in Mechanical Engineering or related Engineering field
• 5+ years of mechanical design and drafting, with a track record of releasing drawings to production
• Expert in CAD (NX required), including sheet metal, weldments, Class A surfacing, and large-assembly management
• Demonstrated Teamcenter administration experience, including workflow creation, troubleshooting, and training.
• Strong command of GD&T per ASME Y14.5, with experience releasing parts to vendors across machining, fabrication, composites, or molding
• Thrives with incomplete requirements and fast-changing designs
• Communicates clearly with engineers, technicians, and suppliers

• Marine hardware experience preferred; automotive, aerospace, or EV also relevant
• Background in composite structures or large weldment design
• Experience with high-voltage packaging, wire harness, or fluid routing
• Experience partnering with industrial designers to turn sketches into Class A surfaces
• Building CAD standards and PDM structure from scratch at an early-stage company
• Comfortable pushing a fast but sustainable pace
• Enthusiasm for boating and clean energy

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.
