Senior Dynamic Test Engineer

Date: Mar 20, 2024

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 12575 

Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.


We are seeking a Senior Dynamic Test Engineer who will support the Dynamic Testing Group in the Enrichment Science and Engineering Division (ESED), Isotope Science and Engineering Directorate (ISED) at Oak Ridge National Laboratory (ORNL) to support dynamic testing of enrichment devices. In addition, the Senior Dynamic Test Engineer will independently lead programmatic tasks and deliver improvements and solutions to meet the desired KPIs.


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 support for research and development using principles of Integrated Safety Management (ISM) within a division that supports multiple projects and programs.


The Machine Dynamics Group has a successful history supporting projects in the centrifuge science and isotope enrichment areas.  Opportunities in these areas are expected to grow over the next few years, requiring additional qualified staff to successfully perform these challenging and nationally important projects. The successful Senior Dynamic Testing Engineer candidate will provide research and development (R&D) leadership to the group in the characterization of gas centrifuges, centrifuge and component test stands, and test cascades for processing uranium-bearing and stable isotope compounds.


Major Duties and Responsibilities:

Design, installation, testing, and performance evaluation of high-speed rotating equipment and supporting subsystems will be this position’s main activities. These activities will include using appropriate instrumentation and software to effectively evaluate the performance of rotors, suspensions, and other related components while working closely with analysts to validate rotor and subassembly models to ensure accurate prediction of performance. Dynamic testing and analysis of structures will also be part of the position’s responsibilities.


Additional responsibilities for the Senior Danamic Test Engineer are as follow:

  • Establish and conduct research regarding characterization of mechanical system dynamics as it relates to gas centrifuge and enrichment technologies.
  • Serve as a thought leader in the area of dynamic testing for the group, section, and directorate.
  • Serve as a mentor for junior technical staff.
  • Interact with sponsors to define, execute, and report on relevant project elements.
  • Actively collaborate with domain experts from U.S. government laboratories and academia involved in similar efforts.
  • Publish high quality research results in peer-reviewed open or classified journals and conferences, if authorized by the sponsoring agency.
  • Publish and present non-sensitive research in journals and conferences.
  • Develop proposals for cutting edge research and funding.

As a member of the ORNL scientific community, the successful candidate will be expected to commit to ORNL’s Research Code of Conduct. The full code of conduct and a statement by the Lab Director’s office can be found here:


Basic Qualifications:

  • Ph.D. degree in Mechanical Engineering, physics, or related field with 2-5 years of post- graduate experience, or a M.S. Degree and 7-12 years of post-graduate experience.
  • Applied experience in performing dynamic testing of mechanical systems, data analysis, and interpretation of test results including modal analysys.
  • Experience with mechanical system measurements, including instrumentation, signal processing, and data acquisition.
  • Hands on experience with design and installation of testing fixtures, application and selection of sensor suites, selection and operation of excitation methods with data acquisition systems is a plus.
  • Experience in developing test plans and methodologies, instrumenting, fixturing, and executing hands on testing activities, including interpreting, documenting, and summarizing test results.
  • Motivated self-starter with the ability to work independently and to participate creatively in collaborative teams across the laboratory.
  • Ability to function well in a fast-paced research environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever changing needs.
  • Excellent communication (spoken and written), strategic planning, organization, and decision-making skills.
  • Demonstrated prior leadership experience.

This position requires the ability to obtain and maintain a Q clearance from the Department of Energy. As such, this position is a Workplace Substance Abuse (WSAP) testing designated position. WSAP positions require passing a pre-placement drug test and participation in an ongoing random drug testing program.


Preferred Qualifications:

  • Active DOE Q security clearance
  • Experience in dynamic testing acquisition software (m+p, Dewesoft, VTI, HBK, Crystal Instruments, Vibration Research, and other related packages).
  • Strong computational skills with the development and evaluation of signal processing and data analysis tools relating to extraction of information from dynamic test results.
  • Experience in Machine Learning Algorithms and Data Analytics.
  • Experience in Machinary Health Monitoring and Predictive Maintenance.
  • Applied experience in the areas rotor dynamics, bearing selection and modeling, rotor balancing, and dynamic testing, including designing and performing measurements as well as analysis of test results.
  • A record of significant technical publications.
  • Experience with MATLAB and Dyrobes.
  • Experience with machining, GD&T and manufacturing techniques.
