• Strong troubleshooting fundamentals with hands-on hardware replacement.
• The ability to work on-site and collaborate within a system administration team.

What Desired Skills You'll Bring:

• Experience with job schedulers such as Slurm or PBS.
• Experience with HPC cluster managers (e.g., Warewulf, HP CM, xCAT, or Bright).
• Experience with parallel/shared filesystems (e.g., Lustre, WEKA, or DDN).
• Experience with high-speed interconnects (e.g., InfiniBand or Slingshot).
• Experience administering GPU-based platforms, including NVIDIA GPUs and CUDA.
• Experience implementing monitoring tools such as Prometheus and Grafana.
• Container experience (Apptainer/Singularity, Podman, or Docker).
• Exposure to Cloud and/or Kubernetes is a plus.

Education and Experience:

• BS or MS degree in computer science or engineering, or equivalent experience

• At least 8 years of directly related experience
