Network Administrator, Sr. - Oak Ridge, TN
Make an impact in a mission‑driven, high‑tech environment.
Centrus Energy is looking for a skilled and motivated Senior Network Administrator to play a key role in supporting and advancing the IT infrastructure that powers our operations.
In this role you will serve as a high-level technical expert overseeing the performance, security, and reliability of Centrus’ servers, data centers, and infrastructure systems. You’ll work independently on complex assignments, collaborate closely with IT leadership on security and budget planning, and occasionally support cross‑departmental technical initiatives. While reporting to the IT Infrastructure Manager, you may also take direction from project managers on specialized efforts.
What You’ll Do
• Take ownership of server, network, and data center performance—monitoring, troubleshooting, and proactively improving system stability and security.
• Install, configure, and maintain LAN components including switches, routers, firewalls, and both fiber and copper cabling.
• Work alongside IT Support Specialists to resolve complex issues and occasionally assist with desktop support needs.
• Maintain healthy server environments by installing patches, performing upgrades, and managing operating systems, web/application servers, directory services, and other critical platforms.
• Collaborate with IT management and internal customers to support a secure, well‑architected network and server ecosystem.
• Research emerging technologies, tools, and standards to help drive innovation and future capacity planning.
• Support Operational Technology (OT) networks and SCADA systems as needed across the organization.
Who Thrives in This Role
• A self‑starter who excels with minimal supervision and enjoys owning complex technical challenges end‑to‑end.
• Someone comfortable balancing daily operational responsibilities with long‑term planning and continuous improvement.
• A detail‑focused problem solver who values security, reliability, and thoughtful system design.
What You Will Bring
• Bachelor’s degree in Computer Science, Engineering, Business Management, or a related technical field — or an equivalent combination of education and experience.
• At least seven years of hands‑on network experience, or equivalent experience/education blend.
• Strong working knowledge of common network servers, operating systems, hardware platforms, standards, and protocols used in enterprise environments such as those within Centrus' infrastructure.
• Ability to obtain and maintain a DOE Q‑level security clearance (required for this position).
In compliance with federal law, all persons hired will be required to verify identity and eligibility to work in the United States and to complete the required employment eligibility verification form upon hire.
This position will require a pre-employment background check and a pre-employment drug test.
Centrus Energy and all subsidiaries shall abide by the applicable legal requirements. We prohibit discrimination against qualified individuals based on their status as protected veterans or individuals with disabilities and prohibit discrimination against all individuals based on their race, color, religion, sex, sexual orientation, gender identity or national origin.
This position requires the successful candidate to obtain and maintain a Q security clearance. Candidates for positions requiring a security clearance are required to be tested for the absence of any illegal drug as defined in 10 CFR 707.4 prior to an offer of employment being made. In addition, once employed, employees will become part of a random drug testing program and may also be tested in the event of any incident causing injury or causing damage to property, or if it is determined that there is a reasonable suspicion the employee is under the influence of drugs or alcohol. This position will require preemployment background check on the part of the Company and in order to receive a Q security clearance, a background investigation by the Federal government. Subsequent Federal government reinvestigations may be required.
