  • Collaborate closely with researchers and technical staff to improve reliability, automation, and usability of shared infrastructure.

Key Qualifications
  • Experience with Linux systems administration in an enterprise or research environment.
  • Experience with Linux domain administration, identity or directory services, centralized authentication, and host lifecycle management.
  • Knowledge of networking fundamentals including TCP/IP, VLANs, firewalls, VPNs, and multi-site architectures.
  • Experience with configuration management and automation tools such as Ansible, Puppet, Chef, or Salt.
  • Experience with containerization and container orchestration technologies.
  • Storage administration experience including RAID, volume management, network file shares, backup, and recovery.
  • Strong Python and Bash scripting fundamentals.
  • Virtualization experience with enterprise hypervisors such as VMware, Hyper-V, KVM-based platforms, or similar technologies.
  • U.S. citizenship required.
  • Ability to obtain and maintain a DoD Secret clearance.

Preferred Qualifications
  • Experience administering airgapped, disconnected, or classified networks, including offline mirrors, removable-media transfer, and manual patch workflows.
  • STIG, CIS benchmark, or other compliance baselining experience; familiarity with NIST SP 800-171 / CMMC.
  • Identity and access management experience including directory services, LDAP/Kerberos, SSO/OIDC, PKI, and hardware-token deployment.
  • Distributed NAS administration experience.
  • Database administration experience in relational and/or search and analytics platforms.
  • Monitoring and SIEM experience including metrics and dashboarding, log aggregation, and host-based intrusion detection.
  • Experience with CI/CD and artifact management including pipelines, container registries, and offline package mirrors.
  • Experience with bare-metal and golden-image provisioning tooling.
  • Experience supporting GPU compute clusters or self-hosted AI/ML inference workloads.
  • Experience establishing, writing, and enforcing infrastructure policy.
  • Ability to work independently with minimal oversight.
  • Relevant certifications such as RHCSA, CompTIA Linux+, or Security+ (DoD 8570 IAT Level II).
