• Maintain documentation: network diagrams, asset inventories, configuration baselines, SOPs
• Implement and enforce security policies (patching, firewall rules, access controls)
• Manage backups, disaster recovery procedures, and data retention policies
• Support researchers/engineers with environment setup for experiments, benchmarks, or testing (e.g., provisioning compute nodes, storage volumes, network configs)
• Track licensing, warranties, and hardware lifecycle (procurement to decommissioning)
• Coordinate lab scheduling/resource allocation if shared across teams

Required Skills/Qualifications

• Strong Linux administration experience (Ubuntu/RHEL/CENTOS)
• Networking fundamentals (TCP/IP, VLANs, bonding/LACP, basic troubleshooting)
• Experience with storage systems (SAN/NAS, parallel filesystems like Lustre/GPFS a plus)
• Scripting ability (Bash, Python) for automation
• Familiarity with virtualization/containerization (KVM, Docker) is a plus
