Experience supporting large data systems. A strong desire to innovate and identify new technologies and opportunities and be able to communicate the potential benefits of those choices to others within the team and our research partners. A collaborative and upbeat approach to thrive on the opportunity to build trust and credibility and ultimately become a trusted advisor to our research teams. Active DOE Q, active DOD Top Secret, or active DOD TS / SCI clearance is heavily preferred for consideration. Solid understanding of multiple operating systems and cluster technologies. Experience with Rocky / Centos / RHEL, Ubuntu, VMware. Understanding of HPC platforms to support users with SLURM job submissions and troubleshooting. Experience building and running containerized applications in an HPC environment. Experience with multiple deployment mechanisms like Diskless, Warewulf, and traditional deployment (cobbler, PXEboot, and / or Bright). Experience managing systems utilizing GPU (NVIDIA and AMD) clusters for AI / ML and / or image processing. Knowledge of networking fundamentals including TCP / IP, traffic analysis, common protocols, and network diagnostics. Experience with Infiniband networks and diagnostics.
