If you’re the kind of engineer who gets excited by vibration plots, high-speed machinery, and solving problems most people don’t even know exist, this role was built for you. As a Rotor Dynamics Analyst at Centrus Energy, you’ll work at the cutting edge of gas centrifuge technology—supporting systems that play a critical role in clean energy and national security. From analyzing complex rotating systems to improving real-world manufacturing performance, you’ll combine deep technical expertise with hands-on engineering problem solving in an environment where innovation moves fast and every detail matters.

What You’ll Do 

• You’ll partner closely with engineering, manufacturing, and testing teams to keep high-speed rotating systems operating at peak performance.
• In this role, you’ll analyze vibration and operational data, perform rotor dynamic modeling and simulations, support rotor balancing activities, and help troubleshoot complex equipment behavior.
• You’ll also conduct dynamic testing, apply digital signal processing techniques, develop custom diagnostic tools, and contribute to the continuous improvement of test procedures and automation efforts.
• Along the way, you’ll serve as a technical expert in rotor dynamics and vibration analysis while helping drive innovation across advanced centrifuge technology programs.

• Bachelor’s degree in mechanical engineering, Aerospace Engineering, or a related engineering field. (required)

Required Skills, Experience, and Qualifications

• Due to federal contract security requirements, candidates must be able to successfully pass a federal background investigation to secure and maintain DOE Q security clearance. (required)
• Due to federal contract security requirements, this position requires U.S. Citizenship. (required)
• Health & Safety training, medical monitoring, and client-driven drug and background testing. (required)
• 5+ years of experience in rotor dynamics, vibration analysis, or related technical disciplines.
• Strong knowledge of high-speed rotating machinery dynamics and system behavior. 
• Experience with vibration diagnostics, modal analysis, and rotating equipment troubleshooting.
• Proficiency in modeling and simulation of rotating systems. 
• Experience applying digital signal processing techniques to engineering data. 
• Familiarity with software development and engineering analysis tools, with Python strongly preferred. 
• Experience using Finite Element Analysis software such as ANSYS or similar platforms. 
• Solid understanding of mechanical vibrations and system dynamics.  

Preferred Qualifications and Location Details

• Active Q clearance is strong preferred.
• Master’s degree or Ph.D. in Mechanical Engineering or a related field. 
• 8+ years working with gas centrifuges or other ultra-high-speed rotating systems. 
• Familiarity with automated testing, instrumentation, and data acquisition systems. 
• Onsite position in Oak Ridge.
• One-year base assignment with possibility of extension and/or conversion after.
