The position leads mechanical design and analysis, creates and maintains models and drawings, mentors junior engineers, and collaborates across engineering, manufacturing, and test teams. The role also involves presenting and defending design decisions to internal and external stakeholders and helping build and test prototype systems in laboratory and at-sea environments.

Requirements

• A bachelor's degree in mechanical engineering or a closely related field and 12–16 years of relevant experience, or a master's degree in mechanical engineering or a closely related field and 10–14 years of relevant experience.
• Ability to obtain a Secret clearance or higher.
• Strong organizational skills and attention to detail.
• Ability to plan, prioritize, and organize work.
• Strong, effective, and professional written and verbal communication and interpersonal skills.
• Ability to lead interdisciplinary technical teams.
• Initiative in troubleshooting mechanical issues and creativity in choosing approaches in non-routine situations.
• Demonstrated experience with SolidWorks and SolidWorks PDM Pro.
• Experience creating drawings to ASME standards, including applying geometric dimensioning and tolerancing per ASME Y14.5.
• Experience analyzing mechanical systems, including thermal, structural, and hydrodynamic analysis, using hand calculations and commercial FEA/CFD software such as SolidWorks, ANSYS, and COMSOL.
• Background designing, building, and testing prototype and limited-production hardware systems.
• Ability to lift heavy objects, climb ladders, and work in enclosed spaces.

Nice To Haves

• Maritime systems and/or ocean engineering experience.
• Experience with UUVs, operating and control systems, associated electronics and sensors, launch and recovery subsystems, and system-to-host interfaces, including acoustic ranging and communications.
• Experience using manual machine tools such as mills and lathes and fabrication equipment such as saws, grinders, and welders.
• Experience with additive manufacturing processes, including 3D printing.
• Familiarity working as part of an Integrated Product Team (IPT) on Department of Defense programs of record.
• Knowledge of subsea acoustic systems, including projectors and hydrophones.
• Experience designing for tight-tolerance optical systems.
• Knowledge of corrosion processes and designing systems for long-term operation in corrosive environments.
• Fiber optic telemetry experience.

Responsibilities

• Lead the design and analysis of UUV-related mechanical systems, including propulsion, dynamic control, structure, electronics, mission payloads, and launch and recovery systems.
• Mentor and provide leadership to junior mechanical engineers.
• Create 3D mechanical models and detailed designs using SolidWorks, produce drawings per ASME Y14.100, and maintain models and drawings in SolidWorks PDM Pro.
• Perform structural, vibration, shock, thermal, and hydrodynamic analyses using hand calculations and tools such as SolidWorks, ANSYS, and COMSOL.
• Present mechanical designs and justify engineering decisions during internal and customer engineering reviews.
• Collaborate with electrical engineers, software developers, and systems engineers to ensure complex systems meet customer requirements.
• Work with manufacturing and test and evaluation teams to build prototype systems and conduct laboratory and at-sea testing.
