Marine Systems Engineer

Arc Boats•Torrance, CA

About The Position

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.

Requirements

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
This is an active role that will require consistent physical activity and standing for a majority of the shift
Ability to lift, push, and pull 50 lbs
