  • Developing detailed engineering drawings and specifications for enclosures using CAD software and in accordance with ASME Y14.5 2018 and ASME Y14.41.

  • Collaborating with BMS electrical engineers to ensure proper thermal management and electromagnetic compatibility within the enclosure.

  • Working with manufacturing partners to ensure enclosures are produced to meet design specifications and quality standards.

  • Performing or oversee qualification testing of enclosures to verify compliance with military standards.

  • Eight (8) years professional technical experience including at least six (6) years specialized experience in the areas of either weapons manned or unmanned, robotic, or weapon control system concept definition, design, integration, and engineering. Specialized experience shall also include experience as a mechanical engineer performing mechanical engineering analysis and design, mechanical engineering software tools, coordinating mechanical fabrication, and mechanical engineering test techniques.

  • Must have an Active SECRET US Government Clearance. Note: US Citizenship is required to obtain a SECRET Clearance.

  • Proficiency in CAD software (e.g., SolidWorks) and FEA/CFD (Solidworks Simulation, Flow, Nastran, Altair, LS-Dyna, ANSYS, etc.) in order to structurally and thermally substantiate design.

  • Experience using manufacturing equipment to produce rapid prototypes; 3D printers, Laser Cutters, Waterjet, Milling Machines, Hand Tools, etc.
