Senior Data Engineer

What we're buildingEvery 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 forWe're looking for someone who's fired up by our mission and ready to build. You'll thrive here if you adapt quickly, take ownership, and care about the details.This is a full-time, on-site role at our Los Angeles headquarters.
