The division leverages an elite staff of scientists and engineers with the world-leading capabilities of Oak Ridge National Laboratory to deliver groundbreaking advancements with a variety of applications, from national security to life-saving medical treatments.

CETD maintains a secure computer network of mid-range clusters, servers, workstations, and other services in support of the division’s projects and science missions. The IT Systems Engineer is responsible for supporting and optimizing IT infrastructure across various projects and facilities. The chosen candidate will work closely with ORNL’s Information Technology Systems Directorate (ITSD) to deploy, automate, monitor, and manage IT systems, ensuring reliable and efficient technology solutions for both research and enterprise needs.

Implement process improvements and document IT best practices.
Collaborate with ITSD staff and vendors to address technical issues and improve overall system usability.
Ensure compliance with ORNL security policies and best practices.
Install, configure and maintain commercial and open-source software.
Develop and maintain disaster recovery plans, backup solutions, and failover strategies to ensure business continuity.
Support and optimize network infrastructure, including switches, firewalls, and connectivity solutions.
Identify and implement continuous process improvements for IT infrastructure and operations.
Lead projects and mentor other IT staff.
Provide off-hours support as required.
Deliver ORNL’s mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace – in how we treat one another, work together, and measure success.

Basic Qualifications:

Demonstrated analytical and problem-solving skills.
Experience supporting multiple organizations within a project or program.
Experience with the marking, handling, and storage requirements of sensitive documents (e.g., CUI, ECI, UCNI, CRD, SRD).
Knowledge of IT infrastructure security and compliance standards with a heavy focus on NIST 800-53 R5.
Familiarity working with and administrating 802.1X.
Ability to function well in a fast-paced environment, set priorities to accomplish multiple tasks within deadlines, and adapt to ever-changing needs.
