The ideal candidate combines solid mechanical engineering fundamentals, hands-on design experience, and the ability to thrive in a fast-paced, collaborative development environment.

Key Responsibilities

• Drive product and subsystem requirements definition and specification.
• Conduct feasibility studies to evaluate design concepts, risks, and tradeoffs.
• Develop conceptual and detailed mechanical designs, drawings, and models using 3D CAD tools such as Pro/ENGINEER or Creo.
• Perform engineering analyses, including fluid, thermal, vibration, and finite element analysis (FEA).
• Apply geometric dimensioning and tolerancing (GD&T) principles to support robust design intent.
• Complete detailed tolerance stack-up analyses to validate performance and manufacturability.
• Lead and facilitate design reviews throughout the product development lifecycle.
• Coordinate procurement of prototype components and materials.
• Support prototype assembly, integration, and testing activities.
• Execute system-level integration and verification testing.
• Create assembly instructions and test procedures to support development and manufacturing readiness.
• Prepare documentation for release and ensure effective handoff to manufacturing.
• Collaborate closely with optics, systems, manufacturing, and service engineering teams to ensure seamless subsystem and system integration.
• Partner with suppliers to define requirements, monitor progress, and ensure design objectives are met.
• Identify and resolve product issues across all phases of the product lifecycle.

Typical Design Challenges

• Precision mechanical design involving large and complex tolerance stack-ups
• Design for ultra-high vacuum environments

Preferred Qualifications
