About

The Role

This position will coordinate and participate in the design and fabrication of various systems and equipment used in the referenced fields.

The ability to use depth of mechanical engineering knowledge and experience to develop cutting edge technology is the objective. More detailed required and desired skills are described below.

  • This position will be responsible for the coordination and delivery of significant, high value systems/sub-systems.
  • Collaborate with Engineering, Physics and Operations groups to clarify and define requirements
  • Develop mechanical systems and designs that satisfy requirements.
  • Coordinate and organize design reviews
  • Contribute subject matter expertise to the team
  • Organize multidisciplinary project teams and make estimates for cost and schedule
  • Coordinate with electrical, controls, design engineers and engineering analysis staff
  • Write and/or review specifications and procedures
  • Locate and select qualified manufacturers
  • Follow fabrication and delivery of components
  • Participate in installation and commissioning activities
  • Some limited travel required
About You
  • B.S., M.S. or Ph.D. in Mechanical Engineering or closely related field.
  • Physics, Aerospace, and Electrical Engineering would be considered favorably as dual major degrees, supplementary education or as alternatives to Mechanical Engineering for an especially well qualified candidate.
  • Approximately 10 years of relevant experience in large component design and fabrication for technical industries such as aerospace, nuclear, automotive, petroleum processing, proton therapy, national laboratories, or similar is typical for this role. This is a guideline rather than a fixed threshold: candidates with fewer years but strong alignment with the desired skills described below are encouraged to apply, and candidates newer to some of these disciplines may be considered for a developmental path into the role.
  • Experience in a research and development environment.
  • Thorough knowledge of engineering fundamentals including basic physics, electromagnetism, statics/dynamics, basic circuit theory, structural mechanics, controls, thermodynamics, fluid dynamics, heat and mass transfer.
  • Ability to respond flexibly to discovery of new requirements. Much of the work at TAE involves research so change is expected thus the inherent ability to change designs/approaches as the need arises is essential.
Preferred Qualifications
  • Experience with project organization tools such as Microsoft Project, Jira, Confluence, or other project management tools and working knowledge of basic Project Management principles would be considered very favorably.
  • Ability to coordinate team meetings and prepare/deliver technical presentations to both large and small groups would be beneficial.
  • Medical Device or aerospace engineering and design process implementation experience
  • Finite element analysis (FEA) familiarity (structural static, dynamic, electromagnetic, fluids/CFD, particle tracking, etc)
  • Experience with flow systems undergoing phase change
  • Experience in the design of electromagnets, up to and including superconducting devices
  • Basic understanding of high voltage electrical systems
  • High or ultra-high vacuum system experience (electropolishing, out gassing, cleaning processes, cryopumps, turbopumps, backing pumps, metal seals, getter systems, gate valves, etc.)
  • Experience with high power RF system design
  • Experience with particle accelerator systems (electrostatic, linear, synchrotrons, cyclotrons, etc.)
