Job summary

Arc is hiring a Mechanical Engineer to design propulsion and drivetrain systems for marine vessels, collaborating with naval architects on hull-to-machinery integration and packaging. You will own thermal and fluid systems, perform analyses, and drive design-for-manufacture with suppliers.

The role requires hands-on work in the shop and on water, including sea trials. You will release drawings and specifications, support regulatory compliance, and contribute to a fast-paced marine

• Collaborate with naval architects on hull-to-machinery integration — packaging, weight and LCG, foundation loads, and appendage interfaces.
• Own thermal and fluid systems across the vessel, including cooling loops, pumps, plumbing, bilge, and ventilation.
• Run structural, thermal, and hydrodynamic analysis to size and validate components before they get built.
• Build and execute test plans on the bench, at the dock, and on the water, then turn that data back into design changes.
• Release drawings, GD&T, BOMs, and specifications, and drive DFM/DFA with manufacturing and supply chain.
• Partner with electrical and controls engineers to integrate Arc's powertrain into the vessel.
