Senior Backend Software Engineer

What we’re building

Every idea starts with a problem. Ours was simple: Boats are special — but they’re loud, pollutant, unreliable, and stuck in the past. Gas-powered boats dominate not because they’re great, but because no better option has existed. Until now.

Arc is here to change that. We’re building 100% electric boats from the ground up — quicker, quieter, easier to maintain, and better for the water they ride on. We’re not just swapping gas for batteries. We’re rethinking every detail on the boat — from propulsion and powertrain to software and ownership model — applying first-principles engineering from aerospace and EVs to deliver a better boating experience.

Electric boats haven’t taken over yet. The tech hasn’t been ready. The talent hasn’t been focused here. That’s our opportunity — and we’re moving fast.

Who we’re looking for

We're looking for someone excited by our vision, eager for a challenge, and willing to learn on the job. We pride ourselves on transparency and operate in a lean, high-trust environment that encourages everyone to take ownership over their domain.
