Overview: 

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.

 

Purpose:

The Information Technology Services Division in the Business Services Directorate at the Oak Ridge National Laboratory is seeking qualified applicants for a Senior Linux HPC Systems Engineer position in the Research and Development Systems Engineering group.  The R&D Systems Engineering group exists to facilitate lab goals through systems engineering, integration, and support for the research community at ORNL.  We run clusters, servers, workstations, and other services where science happens at the lab.

 

Our Team

We are responsible for facilitating R&D projects.   We provide design, deployment, optimization, monitoring, and tooling support across multiple clustered infrastructures for the research organizations that we support.  We support clusters that range in scope from just a handful of nodes to 40,000+ cores.

 

What does our ideal teammate look like and what will you be doing?

Our primary goal is to partner with research organizations to enable research excellence and delivery at ORNL.  We work with other clustered computing and HPC groups to help research programs identify the best solutions for their needs.  When we build environments for our customers, you will work with our team to design, implement and maintain the systems for our customers from inception to retirement.
