Qualifications

• Bachelor’s degree in Mechanical Engineering or related Engineering field.
• 2+ 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 (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
