Job summary

Arc, a leader in electrifying the marine industry, seeks a seasoned mechanical design engineer to craft propulsion and drivetrain systems for vessels. You will own design through build and testing, collaborate with naval architects for hull-to-machinery integration, and ensure compliance with marine standards.

You will work hands-on in the shop and on the water, with opportunities to influence product development and scale production across models.

Qualifications

• Bachelor's degree in Marine Engineering, Naval Architecture & Marine Engineering, Ocean Engineering, or Mechanical Engineering.
• 3+ years designing and releasing mechanical systems for production, ideally on vessels or vehicles.
• Background in machine design fundamentals—statics, dynamics, thermodynamics, fluids, and tolerance stack-up.
• Proficiency with 3D CAD (SolidWorks, NX, or CATIA) and PDM/PLM workflows.
• Experience owning a design through build, test, and iteration rather than handing it off at release.
• Ability to work hands-on in the shop and on the water, including occasional sea trials.
• Active role requiring consistent physical activity and standing for a majority of the shift.
• Ability to lift, push, and pull 50 lbs.
• ITAR compliance: U.S. person required.

Responsibilities

• Designing marine propulsion and drivetrain systems, including shafting, couplings, mounts, seals, bearings, and steering hardware.
• Collaborating with naval architects on hull-to-machinery integration—packaging, weight and LCG, foundation loads, and appendage interfaces.
• Owning thermal and fluid systems across the vessel, including cooling loops, pumps, plumbing, bilge, and ventilation.
• Running structural, thermal, and hydrodynamic analysis to size and validate components before they get built.
• Building and executing test plans on the bench, at the dock, and on the water, then turning that data back into design changes.
• Releasing drawings, GD&T, BOMs, and specifications, and driving DFM/ DFA with manufacturing and supply chain.
• Partnering with electrical and controls engineers to integrate Arc's powertrain into the vessel.
• Supporting USCG, ABS, and ISO compliance and evaluating suppliers for critical marine hardware.
