HPC Linux System Administrator

MRI Technologies has an exciting opportunity for an HPC Linux System Administrator on the JETS II contract at NASA Johnson Space Center. You will support the Flight Sciences Laboratory (FSL), one of JSC's primary computing facilities-over 700 machines, 26,000 cores, and 10+ petabytes of storage serving more than 1,000 users. The analyses running on FSL infrastructure support nearly every major NASA program, including International Space Station (ISS), Orion, Space Launch System (SLS), Commercial Crew, Human Landing System (HLS), Moon Base, and many others.

You will work with a team of HPC System Administrators to build and maintain all FSL services. This will include High Performance Compute (HPC) administration, high-end Linux workstation administration, high-speed networking, and high-speed parallel filesystem administration. A core part of the role is bringing a deep understanding of container technologies and how best they can be used in an HPC environment-FSL uses containers so users can bring their own environments (often older OS versions or older package stacks) into the cluster. Day-to-day tasks include investigating system problems, proactively monitoring system health, and working with FSL users to make sure they can support the NASA human spaceflight mission.
