• Own component and system-level design packages: 3D models, drawings, tolerance stacks, and GD&T using industry-standard CAD/PLM tools.
• Perform structural, thermal, and vibration analysis (FEA) to validate designs against MIL-STD and naval shock/vibration requirements.
• Partner with electrical, systems, and manufacturing engineering to integrate mechanical designs into complex electromechanical assemblies.
• Support prototyping, test planning, and root-cause investigations during qualification and environmental testing.
• Mentor junior engineers and contribute to design reviews, technical proposals, and program milestone deliverables.
• Interface directly with customers and Navy stakeholders on technical requirements and design trade-offs.

Education & Experience Requirements

• Bachelor's degree in Mechanical Engineering (or related field); Master's a plus.
• 8+ years of mechanical design experience, ideally in defense, aerospace, marine, or other highly regulated industries.
• Experience serving as the technical lead for project teams spanning design, analysis, and test.
• Hands-on expertise with SolidWorks, Creo, or NX and FEA tools (ANSYS, Abaqus, or similar).
• Working knowledge of MIL-STD-167, MIL-S-901 (shock), GD&T, and DFM/DFA principles.
• Experience taking designs from concept through production, including test and qualification support.
• Strong communication skills - you can explain a tolerance stack to an engineer and a schedule risk to a program manager.
