Purpose

Experienced Senior Linux Administrator to support and evolve a Linux infrastructure in a compliance-driven environment for the Advanced Technology Laboratory (ATL).

Responsibilities

• Under general direction, perform Linux computer systems installation, configuration, administration, maintenance, troubleshooting, and end-user support for software’s, servers, workstations, laptops, and virtual machines. This is a hands-on role with a clear near-term mission: modernize and standardize the existing infrastructure — rebuilding systems onto a lean, consistent, well-governed baseline. This role operates with a high degree of autonomy — and will be expected to own infrastructure initiatives end-to-end, from planning through execution, with minimal daily supervision.
• Ensure Linux systems integrate properly with SAN/NAS storage and backup infrastructure; partner with the storage administration team on backup services, recovery operations, troubleshooting, and escalation.
• Support infrastructure modernization efforts, including assessing, rebuilding, and redesigning existing Linux systems; standardization; and creation of golden images with automated provisioning pipelines (e.g., PXE/Kickstart).
• Administer configuration management tooling (Salt/Ansible) to enforce consistent, auditable configurations across the environment.
• Establish and maintain repository infrastructure for software distribution and patching — leveraging the central IT mirror and standing up a local mirror to meet lab-specific business needs — including point-release control to standardize patch levels across the environment; manage content synchronization, availability, and access controls.
• Perform and maintain Linux, backup and storage systems audits for compliance with established information assurance policies and configuration guidelines.
• Document and maintain processes, procedures and configurations for Linux, storage and backup solution configuration and change management.
• Maintain computer hardware/software inventories and documentation.
• Other related functions as assigned.

Required Qualifications

• Bachelor's degree in computer science or other related field.
• Five years of experience administering Linux systems in an enterprise storage and backup environment, including integration with SAN/NAS infrastructure (multipathing, LVM, filesystems, NFS server/client configuration) and backup/restore operations from the Linux side
• Experience with commonly used concepts, practices, and procedures used in maintaining backup and storage infrastructure
• Experience with FC, iSCSI, or other network storage protocols
• Experience with commonly used concepts, practices, procedures, and tools used in maintaining a Linux enterprise infrastructure, with strong hands-on expertise in Red Hat Enterprise Linux (RHEL) 8/9
• Demonstrated track record of designing and executing Linux infrastructure improvements, from assessment through implementation — not limited to daily operations.
• Experience with shell scripting: Perl, Python, Bash, or similar
• Relevant education and experience may be substituted as appropriate.

Preferred Qualifications

• At least seven years of experience in Linux system administration.
• Current DoD 8570.1/8140 IAT II or greater certification (CySA+, Security+, GICSP, GSEC, or similar approved IA certifications)
• Experience administering Ubuntu systems in addition to RHEL
• Experience creating and maintaining golden images / standardized server templates (RHEL golden images, VMware templates) and automated provisioning (Kickstart, PXE, cloud-init)
• Experience with infrastructure architecture — building, rebuilding, or redesigning existing Linux infrastructure
• Experience administering VMware vSphere environments hosting Linux VMs
• Experience with system configuration management tools such as Salt, Ansible, Kickstart, Cobbler, RHN Satellite, or Puppet
• Experience establishing and maintaining repository/mirror infrastructure (e.g., RHEL/Alma local mirrors, Satellite, Artifactory), including point-release/patch-level control
• Experience with orchestration software such as Kubernetes, Docker, or Podman
• Experience with source code management tools such as Subversion or Git
• Experience with web and database hosting environments such as Apache, nginx, MySQL/MariaDB, or PostgreSQL
• Experience supporting compute-heavy workloads on physical (bare-metal) servers
• Experience with infrastructure migrations (e.g., NAS-to-array data migrations, storage consolidation)
• Familiarity with compliance frameworks (e.g., NIST 800-171, CMMC, STIGs) in controlled environments
• Relevant certifications (RHCE or equivalent) a plus
