Description:

Columbia Technology Partners is seeking a System Administrator to support the operation, maintenance, and reliability of internal and customer environments across both classified and unclassified systems. This position is ideal for an experienced Linux administrator who is comfortable working across virtualization, storage, identity, networking, and security rather than being limited to a single technology area.

The System Administrator will manage Linux servers, user virtual machines, shared storage, identity services, and supporting network infrastructure. The role will also contribute to vulnerability remediation, system documentation, and the continued availability and performance of mission-critical environments.

Key Responsibilities:

• Administer Oracle Linux 8, 9, and 10 systems, including installation, configuration, patching, monitoring, maintenance, and troubleshooting.
• Manage unclassified user virtual machines using Oracle Linux Virtualization Manager (OLVM).
• Maintain Oracle ZFS Storage Appliance (ZS11-2) shared storage supporting classified and unclassified environments.
• Support FreeIPA identity management and DNS services within the unclassified environment.
• Configure, maintain, and troubleshoot network connectivity and Cisco IOS-XE devices in coordination with network teams.
• Assess Common Vulnerabilities and Exposures (CVEs), track remediation activities, and support IAVM management.
• Develop and maintain scripts to support system administration, configuration, maintenance, and automation activities.
• Document system configurations, maintenance procedures, incidents, troubleshooting activities, and system changes.
• Take ownership of system and network reliability, proactively identifying and resolving issues to minimize downtime for users.

Qualifications:

• Minimum of 5 years of professional System Administrator experience, with hands‑on experience administering Linux-based environments.
• Strong Linux troubleshooting skills and the ability to support interconnected virtualization, storage, identity, and network infrastructure.
• Intermediate knowledge and hands‑on experience with Cisco network administration and network troubleshooting.
• Advanced scripting skills, including the ability to modify existing scripts and develop new automation or administration scripts.
• Strong documentation and communication skills, with the ability to clearly document configurations, procedures, incidents, and system changes.
• Active CompTIA Security+ certification.

Desired Skills:

• Experience administering Oracle Linux, particularly versions 8, 9, and/or 10.
• Strong knowledge of CVEs, vulnerability remediation, and IAVM management.
• Experience configuring and troubleshooting Cisco IOS-XE network infrastructure.
• Experience with Oracle ZFS Storage Appliance or comparable enterprise storage platforms such as NetApp or Dell EMC.
• Experience with virtualization platforms such as OLVM, oVirt, Proxmox, VMware, or similar technologies.
• Familiarity with FreeIPA, Linux-based identity management, and DNS services.
• Experience supporting infrastructure across both classified and unclassified environments.
