Responsibilities

Lead activities that advance the state-of-the-art in gas centrifuge isotope separator (GCIS) design working closely with analysis, fabrication, assembly, and testing personnel

Design complex components and subassemblies for high-speed rotating equipment using machine design fundamentals and design for manufacturing. Focus areas include: rotors, motors, bearings, suspensions, composites, vibrations, and containment safety design

Progress new designs through various stages of testing toward volume production

Design containment boundary joints (e.g., mechanical assembly interfaces, electrical feedthroughs, weldments, etc.) to high and ultra-high vacuum system best practices

Design precision specialized fixtures and tooling for fabrication, inspection, testing, and assembly

Produce a variety of design output documents including, but not limited to, systems requirements documents, calculations, drawings, bills of materials, specifications, inspection plans, assembly instructions, and test plans/procedures

Utilize SolidWorks 3D CAD to create models and drawings in accordance with ASME Y14.5. Utilize SolidWorks PDM for configuration management

Perform tolerance stack-up and error budget analysis calculations

Facilitate formal design reviews, by preparing review documents, organizing primary design contributors, and fielding review panel comments to satisfactory resolution

Deliver design outputs within communicated schedule and budget guidance, ensuring that documentation is accurate, clear, and supports downstream work activities

Specify materials conforming to national standards (e.g., ASTM, MIL, SAE, UNS, etc.) based on required material properties and technology-specific vacuum and process gas compatibility guides

Identify critical characteristics of components and define the corresponding inspection and acceptance criteria

Work with Manufacturing and Quality staff (both internal to ORNL and with external suppliers) to disposition non-conformances and respond to requests for waivers/deviations

Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success
