Head of Finance - Planning and Analysis

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. Arc is on a mission to electrify the marine industry. We're rethinking powertrains, software, and vessel designs from first principles. 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.

As Arc’s Strategic Finance Manager you will own strategic finance and FP&A across the company. That means owning our financial models and forecasts, driving reporting that goes directly to our CEO and Board, and running our budgeting and planning processes. This role will report to the Director of Finance.

We're looking for someone fired up by the mission and ready to build. This is a full-time, on-site role at our Los Angeles headquarters.
