Mechanical Systems Engineer - Equipment

Job Title: Mechanical Systems Engineer EquipmentJob Description

This role leads the mechanical design, configuration control, and lifecycle management of equipment used to move, lift, tow, launch, recover, transport, and support a cleansheet large autonomous underwater vehicle. You will own the vehicle master model and toplevel assembly, define and enforce CAD standards and modeling conventions, and manage drawing release and PDM workflows. You will take operatorfacing hardware from concept through detailed design, fabrication, and real dockside and atsea use in a handson prototype environment.

Responsibilities

• Own and maintain the vehicle master model and toplevel mechanical assembly, ensuring accuracy, completeness, and consistency across all configurations.
• Define, implement, and uphold CAD standards, modeling conventions, and best practices for mechanical design and large assemblies.
• Develop detailed 3D models and 2D drawings for lifting, handling, rigging, towing, launch, recovery, transport, and support equipment used with a large autonomous underwater vehicle.
• Create and release productionquality drawings with appropriate GD&T, tolerances, and notes to support fabrication and inspection.
• Manage drawing and release processes, including PDM workflows, permissions, release states, revision control, and overall largeassembly health.
• Support engineering change and configuration management activities, ensuring that design updates are controlled, traceable, and properly documented.
• Develop and maintain technical data packages for mechanical equipment, including models, drawings, specifications, and supporting calculations.
• Perform and document structural and loadpath hand calculations to validate lifting and handling designs and support loadrated equipment certification.
• Design tow points, bridles, lifting fixtures, cradles, handling equipment, and launch/recovery mechanisms for dockside and atsea operations.
• Collaborate closely with fabrication, test, and operations teams to ensure designs are manufacturable, safe, and operatorfriendly.
• Support prototype build, integration, and testing activities in a handson environment, including dockside and atsea trials.
• Troubleshoot mechanical issues in the field and iterate designs based on realworld feedback and operational experience.
• Provide training and guidance to team members on CAD standards, drawing practices, and configuration management processes.
• Contribute to continuous improvement of mechanical design processes, tools, and workflows for complex mechanical assemblies.

Essential Skills

• At least 7 years of mechanical design experience on hardware that was actually built and deployed in realworld applications.
• Proven experience designing loadrated lifting, handling, or rigging equipment.
• Strong proficiency with 3D CAD modeling, released drawings, and application of GD&T.
• Working knowledge of structural and loadpath analysis, including performing hand calculations to validate designs.
• Mechanical design engineering experience with mechanisms, lifting and handling equipment, rigging, launch and recovery systems, fixtures, cradles, and towing/tow points.
• Experience designing complex mechanical assemblies and equipment for demanding environments such as shipbuilding, aerospace, or similar industries.
• Proficiency with CAD design, CAD modeling, CAD drafting, and CAD drawings using tools such as CATIA V5, SolidWorks, Creo/Creo Parametric (Pro/ENGINEER), or equivalent CAD software.
• Mechanical engineering background with strong 3D design skills for equipment and mechanisms.
• Ability to obtain and maintain a Secret security clearance.
• Comfort working from concept through fabrication and deployment, including direct interaction with fabrication and operations teams.

Additional Skills & Qualifications

• Experience with launch and recovery systems for marine vehicles.
• Familiarity with ASME B30 or equivalent lifting codes and standards.
• Experience in shipyard, offshore, dockside, or atsea operations.
• background in mechanism and actuated hardware design for demanding environments.
• Experience in defense or maritime robotics applications.
• Exposure to autonomous underwater vehicles (AUV), unmanned underwater vehicles (UUV), or other subsea systems.
• Experience in new product development for complex mechanical or marine systems.
• Shipbuilding or marine industry experience supporting large mechanical assemblies.
• Aerospace industry experience applying rigorous design, analysis, and documentation standards.
• Ability to train and mentor others in CAD standards, drawing practices, and configuration management.

Work Environment

This role operates in a handson prototype environment supporting a new large autonomous underwater vehicle. You will primarily work in a design and engineering setting using advanced CAD tools and PDM systems, while regularly engaging in shop, dockside, shipyard, and testsite activities. The engineer will design and oversee hardware such as tow points, bridles, lifting fixtures, cradles, handling equipment, and launch/recovery mechanisms, then support their fabrication, integration, and realworld use at shipyards, docks, and atsea test locations. The environment emphasizes close collaboration with multidisciplinary teams, frequent interaction with operators and technicians, and direct involvement in testing and operations to validate and refine designs.
