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 Staff Mechanical Engineer at Arc, you will lead the design and integration of complex electromechanical systems across the full vessel lifecycle, from early concept and requirements through prototyping, validation, sea trials, and production. You’ll own the high-voltage power distribution architecture for our largest vessels, such as our e-tug, and set the technical direction for the engineers who build it.
This is a full-time, on-site role at our Los Angeles headquarters, reporting to our Manager, Powertrain Hardware Engineering.
What you'll do
Leading development of complex electromechanical systems across multiple vessel programs, from concept through production
Owning the high-voltage, high-power distribution architecture across mechanical, electrical, thermal, and manufacturing domains
Directing electromechanical packaging for high-voltage assemblies, such as DC-to-AC power conversion cabinets and AC distribution systems, built for manufacturability, serviceability, and the marine environment
Establishing methods and standards for busbar design, system thermal sizing, static and shock/vibration analysis, and harness and fluid system routing
Driving requirements and technical scope, identifying blockers early, and making the key design decisions and trade-offs
Mentoring engineers across levels through design reviews and hands-on technical guidance
Leading technical engagement with component suppliers, partner shipyards, manufacturing teams, and vessel operators
Leading sea trials and in-field validation to verify system performance and resolve complex real-world issues
Traveling occasionally (~15%) to support testing, validation, suppliers, and field operations
Minimum qualifications
Bachelor’s degree in Mechanical Engineering or a related engineering field
8+ years of experience owning complete mechanical or electromechanical systems, including technical leadership of complex multidisciplinary systems from initial design through production
Strong working knowledge of high-voltage electrical systems, including power electronics and HV enclosure and busbar design
Expert fundamentals in structural and thermal engineering
Experience with CAD software such as NX, CATIA, or SolidWorks
Experience with analysis and modeling tools such as MATLAB, Simulink, or FEA packages
Deep expertise in manufacturing methods and design-for-manufacturability (DFM) principles
Practical experience designing, building, debugging, and troubleshooting hardware in production or prototype environments
Sound judgment making high-impact engineering decisions in ambiguous environments
Clear written and verbal communication, including presenting trade-offs to leadership and cross-functional partners
Demonstrated experience mentoring engineers and raising technical standards across a team
Comfortable working hands-on in the field, including on boats and at shipyards
Bonus qualifications
Experience working on commercial vessels or marine systems, including familiarity with Coast Guard and ABS regulations
Experience with fluid system design, including pump sizing, heat exchanger sizing, and hose/pipe routing
Experience with high-voltage battery, power conversion, or power distribution system integration
Exposure to sheet metal manufacturing, CNC machining, composites, or shop tools
Experience creating detailed engineering drawings with strong GD&T fundamentals
Experience with NX and Teamcenter
Comfortable pushing at a fast but sustainable pace
Enthusiasm for boating, marine systems, and the water
