Mechanical Engineer - Powertrain Engineering

<h2>What we're building</h2> <p>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.</p> <p>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.</p> <p>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.</p> <h2>Who we're looking for</h2> <p><strong>Who We're Looking For</strong><br>As Arc’s Mechanical Engineer, you will own the design and integration of complex electromechanical systems across the full vehicle lifecycle- from early concept and requirements through prototyping, validation, sea trials, and production.<br><br>This is a full-time, on-site role at our Los Angeles headquarters reporting to our Manager, Powertrain Hardware Engineering</p> <h2>What you'll do</h2> <ul> <li class="font-claude-response-body whitespace-normal break-words pl-2">Owning the design and integration of complex electromechanical systems across the vehicle lifecycle, from concept through production</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Working across mechanical, electrical, thermal, and manufacturing domains</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Understanding how assemblies, subsystems, and components interact as part of a larger integrated vehicle</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Driving requirements definition, specifications, CAD design, hands-on prototyping, analysis (FEA, numerical modeling, hand calculations), validation, and production support</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Designing with manufacturability, serviceability, reliability, and real-world operating conditions in mind</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Building, testing, troubleshooting, and iterating on hardware in fast-moving development environments</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Working closely with component suppliers, partner shipyards, manufacturing teams, and vessel operators to drive execution</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Supporting sea trials and in-field validation to verify system performance and resolve real-world issues</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Traveling occasionally (~15%) to support testing, validation, suppliers, and field operations</li> </ul> <h2>Minimum Qualifications</h2> <ul data-spread="false"> <li>Bachelor’s degree in Mechanical Engineering or related Engineering field</li> <li>2+ years of experience owning complete mechanical or electromechanical systems, including large assemblies or complex multidisciplinary systems, from initial design through production</li> <li>Functional knowledge of electrical systems, including high-voltage battery systems and power electronics</li> <li class="font-claude-response-body whitespace-normal break-words pl-2">Strong fundamentals in structural and thermal engineering</li&g
