Key Responsibilities

• Design and develop mechanical test systems, fixtures, assemblies, and support hardware.
• Create and maintain 3D CAD models, 2D drawings, and mechanical drawing packages.
• Use Creo / ProE or similar CAD tools to support mechanical design and documentation.
• Apply GD&T, tolerance analysis, and mechanical design principles to support manufacturability and performance.
• Support test systems used in vibration, thermal, hydraulic, RF, electro-optical, and electro-mechanical environments.
• Integrate and validate mechanical test hardware against accuracy, reliability, and performance requirements.
• Troubleshoot design, fit, function, reliability, and production-support issues.
• Recommend design updates to improve performance, reliability, manufacturability, and maintainability.
• Work with electrical, systems, manufacturing, and test teams on hardware integration.
• Evaluate production installations and support modifications to resolve equipment or hardware issues.
• Support design reviews, documentation updates, configuration changes, and release activities.

Required Qualifications

• Bachelor’s degree in Mechanical Engineering or related STEM field.
• 2+ years of mechanical design, product design, test equipment, or engineering support experience.
• Experience with 3D CAD tools; Creo / ProE preferred.
• Experience creating mechanical drawings, assemblies, and drawing packages.
• Knowledge of GD&T, tolerance analysis, and mechanical design fundamentals.
• Ability to support hardware design from concept through integration, validation, and production support.
• Familiarity with manufacturability, fit/function, and design documentation requirements.
• U.S. Citizenship required.
• Ability to obtain and maintain a Secret security clearance.

Preferred Qualifications

• Active Secret clearance.
• Experience with mechanical test equipment, fixtures, tooling, or production-support hardware.
• Experience with mechanical packaging, electronic packaging, chassis design, enclosures, or equipment layouts.
• Familiarity with configuration management tools such as Windchill, cPDM, or similar.
• Exposure to thermal, structural, vibration, shock, or environmental analysis.
• Experience supporting environmental test systems, including vibration, shock, thermal, RF, or electro-mechanical testing.
• Background in aerospace, defense, missile, avionics, or other high-reliability systems.
• Exposure to model-based design, model-based engineering, or systems engineering concepts.
• Experience working with manufacturing, production, test, or assembly teams.
