Working closely with our ISSM, Facility Security Officer, and engineering teams, you will implement security controls, support accreditation activities, and maintain compliant operations in classified spaces.

✅ Key Responsibilities

• Deploy, configure, patch, harden, and troubleshoot RHEL and Windows Server systems.
• Build and maintain virtualization, Kubernetes, storage, backup, and recovery systems for mission-critical workloads.
• Manage access controls, monitor system health, review logs, and remediate vulnerabilities.
• Support security assessments, accreditation documentation, remediation plans, and continuous monitoring.
• Automate repeatable administration tasks and improve alerting and operational procedures.
• Diagnose issues across servers, storage, networking, and applications, including occasional scheduled maintenance or after-hours support.

📌 Required Qualifications

• 5+ years of experience administering IT infrastructure in an enterprise or government environment.
• Current, active U.S. Government Secret clearance or higher, with the ability to maintain it.
• Strong hands-on experience with RHEL, including installation, configuration, patching, troubleshooting, and security hardening.
• Experience administering Windows Server and Kubernetes environments.
• Experience operating virtualized infrastructure, enterprise storage, and backup and recovery systems.
• Experience applying security and compliance requirements in a classified environment.
• Familiarity with applicable Risk Management Framework processes, NIST security controls, and DISA STIGs.
• Working knowledge of networking, identity and access management, monitoring, and incident response.
• Ability to document systems clearly, resolve problems independently, and own infrastructure from deployment through ongoing operations.

⭐ Desirable Experience

• Eligibility for SCI access or experience supporting systems in a SCIF.
• Experience designing infrastructure for high availability and tested recovery.
• Experience automating infrastructure administration and configuration.
• Familiarity with classified network connectivity and the operational requirements of SIPRNet or JWICS.
• Experience preparing accreditation evidence, remediating findings, and supporting audits or inspections.

🎁 Benefits

Classified infrastructure is secure, reliable, documented, and ready to support mission operations. Servers and Kubernetes environments are consistently configured, patched, monitored, and maintained. Virtualization, storage, and backup systems meet workload needs, with recovery procedures that have been tested. Security findings are addressed promptly, and compliance evidence is easy to produce. Engineers and mission operators can depend on the infrastructure and get fast help when issues arise.
