Senior Cloud & Systems Administrator

ATI builds and manages collaborations that conduct research and development of new technologies to solve our nation's most pressing challenges. Our collaborations are custom‑built teams of organizations from industry and academia that develop novel technologies for the federal government. Traditionally, these processes are complicated and burdensome. That's where ATI comes in. We simplify and streamline processes to make it all work.

When you work at ATI, you become a part of something larger than yourself. Our collective work—no matter what department or division you work in—ultimately enables the warfighter, saves lives, and diversifies the industrial base. At our core, ATI is a service organization. We are in service to others; it's what we do, and it's who we are.

The Sr. Cloud and Systems Administrator manages ATI's mixed IT ecosystem, bridging the gap between traditional on‑premises hardware and modern cloud‑based resources. This role is essential for maintaining system stability, security, and performance across hybrid environments. The administrator maintains all of ATI's cloud and on‑premises systems, applications, security, and network configurations; works closely with IT security to ensure proper implementation of security controls;

assesses IT networking/technology requirements for business operations; and acts as a senior technical staff member on projects.

We offer a hybrid schedule (in‑office & remote/work from home) or an onsite schedule with flexible hours. Candidates will need to reside near Charleston, SC to ensure work site flexibility.
