Company: Oak Ridge National Laboratory

Requisition Id 6425 


The Testbed Science and Engineering Group within the Enrichment Science and Engineering Division (ESED) is seeking a Mechanical Engineer. ESED serves the nation in two critical areas: advancing enrichment technologies and exploring stable isotope production and applications. The division leverages an elite staff of scientists and engineers with the world-leading capabilities of Oak Ridge National Laboratory (ORNL) to deliver groundbreaking advancements with a variety of applications, from national security to life-saving medical treatments.

ESED is the national steward for the research, development, and demonstration of centrifuge technology. The successful candidate will provide research and development (R&D) leadership within the group that strategically advances science and technology focused on gas testing of prototype enrichment devices for processing uranium-bearing and stable isotope compounds. 

The Testbed Science and Engineering Group is focused on the development of gas testing test beds and enrichment systems by conceptualizing and designing robust and flexible test beds for using state-of-the-art systems engineering principles. This group is particularly focused on the advancements of test beds and enrichment systems by human-machine interface research and system logic development. Additionally, the group develops and implements advanced control system architectures for centrifuge test beds. This position will have an emphasis in the areas of instrumentation hardware and software, and the successful candidate will make a significant contribution to projects involving isotope enrichment, nuclear nonproliferation, and instrumentation of mission-critical systems.

Major Duties and Responsibilities:

  • Perform research and development of equipment and systems used to process uranium-bearing and stable isotope compounds.
  • Provide technical guidance and leadership to facilitate the design, procurement, fabrication, construction, and installation of testbeds and production isotope enrichment systems supporting multiple enrichment technology programs.
  • Understand and contribute to detailed formal mechanical designs, testing/analysis plans, and fabrication plans in coordination with stakeholder personnel.
  • Provide technical leadership in a team environment. The successful candidate is expected to work collaboratively with coworkers and management, as well as independently, to fully document work performed in the forms of technical reports and presentations and to participate in the development of research proposals. The position involves interfacing with principal investigators, management, engineers, fabricators, modelers, and test campaign personnel.
  • Own specific scopes within the Testing Science and Cascade Engineering Section and the Testbed Science and Engineering Group to deliver designs for world-leading science and technology supporting enrichment sciences.
  • Coordinate internal and external design reviews as well as facilitate tracking and closeout of actions taken during these reviews.
