Test Engineer

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 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 Who we're looking for As a Test Engineer at Arc, you will own component, assembly, and vehicle level prototype testing. That means you'll define test plans, build and instrument test setups, execute testing, analyze data, troubleshoot failures, and work directly with design and manufacturing engineers to drive issues to closure. We're building Arc's test capability — this is your chance to help establish how we test hardware, not simply inherit an existing process.
