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 model, and is now extending its platform to commercial applications including tugs, ferries, and defense with signed contracts.
As Senior CAD Designer, you will own the CAD backbone of Arc's vessels. You'll be responsible for producing production-intent CAD for hull structures, mechanical systems, and powertrain integration; releasing fully dimensioned drawing packages to manufacturing and suppliers; and setting the CAD standards that keep a fast-growing engineering team aligned on a single source of truth.
Key responsibilities include:
- 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 folding learnings back into the models
You'll thrive here if you move fast, take ownership, and care about the details. The role requires someone who can work with incomplete requirements and fast-changing designs while communicating clearly with engineers, technicians, and suppliers.
REQUIREMENTS:
- 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-level CAD proficiency in NX, 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
- Ability to thrive with incomplete requirements and fast-changing designs
- Clear communication with engineers, technicians, and suppliers
BONUS QUALIFICATIONS:
- Marine hardware experience (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
