• Manage and optimize on-premises Type 1 hypervisor platforms (Nutanix, VMware, Proxmox) to ensure high availability and performance.
• Implement and maintain system security controls in accordance with DoD standards and applicable STIGs/RMF requirements.
• Monitor network performance, diagnose connectivity issues, and recommend improvements to infrastructure reliability.
• Manage system patching and update cycles to maintain compliance, reduce vulnerabilities, and minimize operational downtime.
• Administer and maintain backup and recovery technologies; conduct periodic validation of restore procedures.
• Create and maintain thorough documentation of system configurations, procedures, and security policies.
• Build and maintain runbooks, standard operating procedures (SOPs), diagrams, and system configuration baselines.
• Partner with cross-functional IT and security teams to evaluate, implement, and enhance system functionality and security posture.
• Interact effectively with government customers, project managers, and other stakeholders to understand requirements, communicate status, and resolve issues.
• Stay current on emerging technologies, industry best practices, and evolving DoD compliance requirements.

Qualifications

Required Qualifications:

• Bachelor's degree in Computer Science, Information Technology, or a related field with 5 years of relevant experience; or High school diploma/GED with 8+ years of equivalent hands-on experience in a system administration role.
• Active TS/SCI clearance required.
• Open to working day shift (with potential for after-hours support) on site at government facility with occasional local travel between sites.
• Demonstrated experience as a System Administrator in a DoD or similarly regulated, security-conscious environment.
• Active CompTIA Security+ certification required.
• Solid hands-on experience with VMware and/or other enterprise virtualization technologies.
• Strong proficiency in Windows Server administration, including Active Directory and Group Policy.
• Working knowledge of networking protocols, system security best practices, and IT infrastructure management.
• Experience working in environments that require frequent interaction with government customers and cross-functional IT/security teams.
• Proven experience creating and maintaining technical documentation, including SOPs, diagrams, and configuration baselines.
• Proficient in Windows Server administration, patching, and update management.
