Job summary

Arc is seeking an experienced Mechanical Engineer to own the design and integration of complex electromechanical systems for marine vessels. This on-site role at our Los Angeles headquarters leads cross-domain activities from concept to production, coordinating with suppliers, shipyards, and operators to ensure robust, manufacturable solutions.

You will drive requirements, prototyping, validation, and production support, applying CAD and analysis tools while thriving in a fast-paced environment

Qualifications

• Bachelor’s degree in Mechanical Engineering or related field.
• 2+ years of experience owning complete mechanical or electromechanical systems through production.
• Functional knowledge of electrical systems, including high-voltage battery systems and power electronics
• Strong 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
• Strong intuition for manufacturing methods and design-for-manufacturability (DFM) principles
• Practical experience designing, building, debugging, and troubleshooting hardware in production or prototype environments
• Ability to move quickly and make sound engineering decisions in ambiguous environments
• Clear written and verbal communication skills
• Strong time management and prioritization skills
• Comfortable working hands-on in the field, including on boats and at shipyards

Responsibilities

• Owning the design and integration of complex electromechanical systems across the vehicle lifecycle, from concept through production
• Working across mechanical, electrical, thermal, and manufacturing domains
• Understanding how assemblies, subsystems, and components interact as part of a larger integrated vehicle
• Driving requirements definition, specifications, CAD design, hands-on prototyping, analysis (FEA, numerical modeling, hand calculations), validation, and production support
• Designing with manufacturability, serviceability, reliability, and real-world operating conditions in mind
• Building, testing, troubleshooting, and iterating on hardware in fast-moving development environments
• Working closely with component suppliers, partner shipyards, manufacturing teams, and vessel operators to drive execution
• Supporting sea trials and in-field validation to verify system performance and resolve real-world issues
• Traveling occasionally (~15%) to support testing, validation, suppliers, and field operations
