Essential Functions

  • Lead the end-to-end mechanical system architecture for subsea robotic platforms, ensuring optimal trade-offs between performance, manufacturability, and reliability.
  • Design manufacture-ready 3D SolidWorks models of pressure vessels, propulsion systems, actuators, and structural components for deep-sea autonomous vehicles and support systems.
  • Establish and maintain technical standards, anti-corrosion guidelines, and other subsea engineering best practices for mechanical design.
  • Conduct tests and field trials of prototype systems in both simulated and real-world environments.
  • Collaborate with electrical, software, and systems engineering teams to integrate mechanical components into complex robotic architectures.
  • Responsible for maintaining PLM of our system level engineering documentation and CAD
  • Provide mentorship and technical leadership to junior and mid-level engineers.
  • Produce requirements documents, engineering packages, technical reports, and validation plans.
  • Participate in the production and maintenance of mechanical systems through the product life cycle.
  • Conduct FEA and CFD simulations to optimize designs for structural integrity, pressure tolerance, hydrodynamic efficiency, and thermal management.
  • Drive root cause analysis and FMEA for mechanical subsystems, implementing corrective actions and design improvements.
  • Engage with vendors, suppliers, and manufacturing partners to ensure high-quality fabrication and assembly processes.
  • Support technology roadmaps and R&D initiatives, identifying emerging trends in materials, additive manufacturing, and robotics.
  • Travel occasionally (10% anticipated up to 20%) for vendor visits, field testing, or contract manufacturing oversight.

 

Minimum Requirements
  • B.S. in Mechanical Engineering, Mechatronics, or related discipline (M.S. or Ph.D. preferred) from an ABET-accredited program.
  • 10+ years of experience in mechanical design, system integration, and full product lifecycle management, with a focus on robotics, subsea engineering, aerospace, or extreme-environment systems.
  • Expert-level proficiency in 3D CAD tools such as SolidWorks (assemblies, parametric modeling, GD&T, design for manufacturability).
  • Extensive experience with FEA, CFD, and multi-physics simulation tools (e.g., ANSYS, Abaqus, COMSOL, MATLAB/Simulink).
  • Strong knowledge of subsea engineering principles, including pressure vessel design, corrosion mitigation, and hydrodynamics.
  • Experience designing complex electromechanical systems, integrating sensors, actuators, and robotic components.
  • Ability to develop and execute validation strategies, including full-scale prototype testing, environmental qualification, and reliability assessment.
  • Demonstrated success leading cross-functional engineering teams, managing projects, and interfacing with executive leadership, stakeholders, and external partners.
  • Familiarity with ASME, API, ISO, and MIL-STD design and testing standards for marine or aerospace systems.
  • U.S. Citizen

 

Preferred Requirements
  • Experience with end to end autonomous vehicle development (subsea, aerial, or ground-based).
  • Experience with advanced manufacturing techniques (e.g., composites, additive manufacturing, precision machining).
  • Experience with automotive hybrid energy system design
  • Background in risk assessment, failure mode analysis (FMEA), and reliability engineering.
  • Previous leadership experience in a dynamic startup organization or equivalent with limited existing process and structure.
