Mechanical Engineer - Powertrain Engineering

WHAT WE'RE BUILDING

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 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.

WHO WE'RE LOOKING FOR

As a Mechanical Engineer at Arc, you will design and own components and subsystems within complex electromechanical systems, contributing across the full vessel lifecycle, from early concept and requirements through prototyping, validation, sea trials, and production. Your focus will be high-voltage power distribution for our largest vessels, such as our e-tug.

This is a full-time, on-site role at our Los Angeles headquarters, reporting to our Manager, Powertrain Hardware Engineering.
