JOB DESCRIPTION:

• Install, configure, optimize, and administer Red Hat Enterprise Linux (RHEL) servers across enterprise, simulation, and exercise networks (including NDM and PTEN-S).
• Perform routine OS and application patching, kernel updates, and repository management using Red Hat Satellite and disconnected local mirror repositories.
• Harden systems against DISA STIGs using automated tools (Ansible, SCAP Compliance Checker), track findings, and remediate ACAS/Nessus vulnerabilities in response to DoD CTOs/IAVMs.
• Diagnose and resolve complex operating system, storage, network, and service-level issues to ensure maximum uptime across physical and virtualized enterprise infrastructure.
• Maintain and develop Ansible playbooks for baseline configuration management, STIG enforcement, and routine maintenance tasks.
• Provide systems and OS-level technical support to Modeling & Simulation (M&S) and C4I systems during live, virtual, and constructive exercise events.
• Monitor system health, performance, storage allocations, and availability of Linux infrastructure; implement proactive remediation.
• Author and update standard operating procedures (SOPs), system build documentation, and technical troubleshooting guides.
• Collaborate with cross-functional infrastructure and Windows systems engineers to support core services, shared storage, and directory integration.
• Perform other systems administration tasks as assigned.

• Proven experience executing Linux patching, package management, and lifecycle version upgrades utilizing Red Hat Satellite Server or local repository mirrors.
• Strong background in DoD security compliance, including applying and auditing DISA STIGs, and remediating ACAS vulnerability findings.
• Practical experience writing and running Ansible playbooks for automated configuration management and security hardening.
• Solid understanding of core networking and infrastructure services (DNS, DHCP, NTP, SSH, LDAP/Kerberos, NFS).
• Familiarity with virtualization platforms (e.g., VMware ESXi/vCenter) hosting Linux guests.

REQUIRED CERTIFICATIONS:
