  • Strong mechanical design aptitude and desire to learn, particularly if in relation to optical-mechanical assemblies such as mirror and lens mounts, precision mechanisms, and advanced structures.
  • Ability to apply basic physical principles, theories, and concepts within the mechanical engineering field, and general knowledge of other related disciplines.
  • Direct experience in developing detailed mechanical conceptual designs and documentation packages for optical and/or mechanical systems.
  • Proficiency with commercial CAD software, such as PTC Creo Parametric 3.0/4.0, Siemens Unigraphics NX, DS Solidworks.
  • Experience with electro-optical and electro-mechanical program manufacturing operations and processes.
  • Experience in design, assembly, and integration of mechanical / optical systems.
  • Experience in Geometric Dimensioning and Tolerance (GD&T) analysis for drawings.
  • Experience with Microsoft Office tools (Word, Excel, PowerPoint, and Visio).

  • U.S. Citizenship is required.

Desired Skills:
  • Prior experience in the Aerospace or Defense industry, ideally with similar or related hardware and/or mechanisms.
  • Familiarity with space flight hardware, including involvement in material properties selection trades, sensitive hardware and electronics components handling.
  • Flight-hardware experience in assembly, integration, and test environments, to ensure hardware system level performance (e.g. vibration/shock/modal testing, thermal cycling per MIL-STD-1540, ESD/EMI/EMC per MIL-STD-461).
  • Laboratory test experience, to include use of control software such as National Instruments LabVIEW, MathWorks Simulink.
  • Machine shop hands-on experience (lathes, end mills, grinders, et. al.), CNC machine operation experience, and/or additive manufacturing fabrication experience a plus.
  • Additional CAD and analysis software experience, including experience with mechanical stress analysis, thermal analysis, and various support software packages (i.e. MathWorks MATLAB, MSC Nastran/Patran, Ansys Fluent, Mathmatica), desired but not required.
  • Possess an active or in scope SSBI/SCI and/or DoD Secret/Top Secret security clearance.

Required Education: Bachelor of Science in Mechanical Engineering, or related engineering field, from an accredited university.

Desired Education: Master of Science or Ph.D. in Mechanical Engineering, or related engineering field, from an accredited university.

U.S. Citizenship status is required as this position will need a U.S. Security Clearance within 1 year of start date.

This position requires either a U.S. Person or a Non-U.S. Person who is eligible to obtain any required Export Authorization. 119833
