Perform mechanical design and analysis of structures, housings, pressure vessels, frames, and mechanisms for autonomous and unmanned undersea vehicles (AUV/UUVs)
Develop detailed 3D CAD models and 2D engineering drawings using SolidWorks, including application of GD&T and tolerance stack-ups
Manage and maintain engineering data within PTC Windchill, ensuring configuration control and design traceability
Translate system and customer requirements into detailed mechanical design solutions and component-level specifications
Support concept development, trade studies, and design optimization to balance performance, reliability, manufacturability, and cost
Design components and assemblies to withstand undersea environmental conditions, including pressure, corrosion, shock, vibration, and thermal effects
Support prototype fabrication, assembly, and integration, including hands-on troubleshooting and design refinement
Develop and execute test plans and procedures to validate mechanical designs during bench, lab, and in-water testing
Analyze test results, document findings, and implement design improvements or corrective actions
Collaborate with electrical, software, systems, manufacturing, and test engineering teams to ensure integrated vehicle performance
Interface with suppliers and manufacturing partners, supporting design for manufacturability (DFM), design for assembly (DFA), and supplier technical reviews
Prepare and support technical documentation, including design descriptions, reports, and materials for formal design reviews (PDR, CDR, TRR)
Support transition of designs from R&D to production, including build support, issue resolution, and configuration updates
Ensure compliance with applicable engineering standards, specifications, and quality requirements
Contribute to continuous improvement of engineering processes, tools, and best practices
