Senior Mechanical Engineer

About the role

The Mechanical Engineer will own the design and integration of complex electromechanical systems across the full vehicle lifecycle, from concept through production. They will work across mechanical, electrical, thermal, and manufacturing domains, understanding how assemblies, subsystems, and components interact as part of a larger integrated vehicle.

Responsibilities

• Owning the design and integration of complex electromechanical systems across the vehicle lifecycle, from concept through production
• 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
• Occasional travel (~15%) to support testing, validation, suppliers, and field operations

Requirements

• Bachelor’s degree in Mechanical Engineering or related Engineering field
• 4+ years of experience owning complete mechanical or electromechanical systems, including large assemblies or complex multidisciplinary systems, from initial design 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 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

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
• Deep experience with high-voltage battery system design or integration (beyond general functional knowledge)
• Exposure to sheet metal manufacturing, CNC machining, composites, or shop tools
• Creating detailed engineering drawings with strong GD&T fundamentals
• Comfortable pushing at a fast but sustainable pace
• Enthusiasm for boating, marine systems, and the water

Skills

• Ownership over both your work and the company’s success
• Empathy for colleagues and for customers
• Humility in problem solving and collaboration
• Pragmatism for navigating ambiguity quickly and sensibly
