About the role

  • Execute integrated mechanical design and analysis activities, ensuring alignment across functional and performance requirements, physical architecture and packaging constraints, and manufacturability, reliability, and lifecycle considerations
  • Develop and mature concepts, layouts, and detailed designs for mechanical systems and components, including rotating machinery, actuation systems, mechanical control elements, electro-mechanical assemblies, and electronics packaging, with exposure to maritime and undersea systems as applicable
  • Perform and support multi-disciplinary analysis (structural, thermal, vibration, fluid, and system-level modeling), including generating loads, defining boundary conditions, building models, and correlating analytical results with test data and field performance
  • Translate system requirements into physical architectures and executable design solutions, including space claim definition, system layout, interface definition, and cross-domain integration across mechanical and electrical systems, supported by early-stage trade studies and concept evaluations
  • Support early-phase engineering efforts through concept definition, feasibility assessments, development of preliminary models and layouts, and providing engineering inputs to scope, cost, and schedule planning
  • Develop and maintain complete technical data packages, including 3D models, drawings, specifications, and analysis artifacts, ensuring accuracy, completeness, and configuration control
  • Define and execute development, qualification, and acceptance testing, ensuring alignment with system requirements and validation of analytical predictions
  • Implement design changes across the product lifecycle while maintaining configuration control, traceability, and alignment with program objectives
  • Support supplier engagement through technical coordination, component qualification, and resolution of design, manufacturing, or performance-related issues
  • Participate in or lead root cause and corrective action investigations (RRCCA), integrating insights from design, analysis, manufacturing, and field data to drive resolution and continuous improvement

Requirements

  • Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 5 years prior relevant experience or an Advanced Degree in a related field and minimum 3 years of experience
  • Demonstrated experience in two or more of the following areas: mechanical design across the full product lifecycle (concept through production); multi-disciplinary engineering analysis (FEA, thermal, fluid, or system-level modeling); and system integration and packaging of electro-mechanical systems
  • Prior experience using NX or a comparable CAD tool (minimum 3 years)
  • Prior experience using PLM systems such as Teamcenter or equivalent (minimum 3 years)
  • Experience utilizing engineering analysis tools such as ANSYS, Simulink, Mathcad, or equivalent
