SYSTEM ADMINISTRATOR LEVEL 3 - VMWARE/LINUX INFRASTRUCTURE SPECIALIST
LEAD ENTERPRISE IT INFRASTRUCTURE FOR MISSION-CRITICAL DEFENSE SYSTEMS
We're seeking an experienced System Administrator Level 3 with deep expertise in VMware virtualization and Linux environments to manage and optimize complex IT infrastructure supporting defense operations. This role requires 15 years of progressive systems administration experience, combining advanced technical skills with strategic problem-solving capabilities to ensure maximum uptime and performance of critical systems.
THE OPPORTUNITY
As a System Administrator Level 3, you'll be responsible for the architecture, implementation, and optimization of enterprise-scale IT infrastructure spanning virtualized environments, Linux/UNIX systems, and Windows platforms. You'll tackle complex integration challenges, lead incident resolution efforts, and drive infrastructure improvements that directly impact mission success. This position requires IAT Level II certification and offers the opportunity to work with cutting-edge technologies in a high-stakes environment.
WHAT YOU'LL DO
Advanced Infrastructure Management
• Analyze and resolve complex problems associated with server hardware, applications, and software integration
• Configure and manage VMware vSphere environments including ESXi hosts, vCenter, and distributed virtual switches
• Administer enterprise Linux distributions (RHEL, CentOS, Ubuntu) and UNIX systems at scale
• Implement and maintain Windows Server environments integrated with heterogeneous infrastructure
• Design and optimize storage solutions including SAN/NAS architectures and backup strategies
System Operations Excellence
• Install, configure, and maintain operating system software across multiple platforms
• Troubleshoot and maintain integrity of network components including switches, routers, and firewalls
• Implement operating system enhancements to improve reliability and performance
• Perform system capacity analysis and planning for future growth requirements
• Optimize system operations and resource utilization across virtual and physical infrastructure
Technical Leadership & Support
• Provide Tier 1 (Help Desk) and Tier 2 (Escalation) problem identification, diagnosis, and resolution
• Lead complex troubleshooting efforts for critical production issues
• Manage daily configuration and operation activities of enterprise IT systems
• Deliver detailed analysis and feedback to agency management for escalated tickets
• Support dispatch system operations and remain engaged through complete problem resolution
Architecture & Integration
• Support the design of systems and mission architecture with associated hardware recommendations
• Demonstrate working knowledge of system administration interdependencies within Service Oriented Architecture (SOA)
• Integrate diverse technologies including client/server/storage/network devices and mobile platforms
• Ensure seamless interoperability between virtualized and physical infrastructure components
• Drive automation initiatives to improve operational efficiency and reduce manual intervention
Strategic Infrastructure Planning
• Provide in-depth troubleshooting expertise for complex IT system failures
• Conduct performance analysis and implement optimization strategies
• Develop and maintain comprehensive documentation for system configurations and procedures
• Lead disaster recovery planning and testing for critical infrastructure
• Mentor junior administrators and contribute to team knowledge sharing
WHAT YOU'LL BRING
Required Qualifications
• Experience: Fifteen (15) years as a System Administrator in programs and contracts of similar scope, type, and complexity
• Education: Bachelor's degree in Computer Science, Information Technology, Engineering, or technical discipline from an accredited college or university (or 20 years total SA experience)
• Certification: DoD 8570 IAT Level II compliance (Security+ CE, CCNA-Security, CySA+, GICSP, GSEC, or equivalent)
• Clearance: Ability to obtain and maintain required security clearance
Core Technical Expertise
• Advanced VMware vSphere administration including vCenter, ESXi, vMotion, and HA/DRS clusters
• Expert-level Linux system administration across multiple distributions
• Proficiency in Windows Server environments (2016/2019/2022) and Active Directory
• Strong networking knowledge including TCP/IP, VLANs, routing protocols, and firewall configuration
• Experience with enterprise storage technologies (SAN, NAS, iSCSI, Fiber Channel)
• Scripting capabilities in Bash, PowerShell, Python, or Perl for automation
Infrastructure Skills
• Configuration management tools experience (Ansible, Puppet, Chef, or similar)
• Monitoring and alerting platforms (Nagios, Zabbix, SolarWinds, or equivalent)
• Backup and recovery solutions implementation and management
• Performance tuning and optimization for virtualized environments
• Security hardening and compliance (STIG implementation, vulnerability remediation)
• Container technologies experience (Docker, Kubernetes) is a plus
Problem-Solving Capabilities
• Demonstrated ability to troubleshoot complex, multi-system issues
• Experience with root cause analysis and permanent fix implementation
• Strong analytical skills for capacity planning and performance optimization
• Ability to work effectively under pressure during critical incidents
• Excellent documentation and communication skills for technical and non-technical audiences
WHY THIS ROLE MATTERS
Your expertise will ensure the continuous operation of IT infrastructure supporting national security missions. Every system you optimize, every problem you solve, and every enhancement you implement directly contributes to our nation's defense capabilities. You'll work on infrastructure that demands 99.99% uptime, where minutes of downtime can impact critical operations.
THE IMPACT YOU'LL MAKE
In this role, you'll manage infrastructure that powers intelligence analysis, operational planning, and defense communications. Your work in virtualizing and optimizing systems will increase operational efficiency, reduce costs, and improve system resilience. You'll be the technical expert others turn to when complex problems arise, and your solutions will set the standard for infrastructure excellence.
READY TO ELEVATE MISSION-CRITICAL INFRASTRUCTURE?
If you're a seasoned system administrator with deep virtualization and Linux expertise ready to tackle the most challenging infrastructure problems in defense, we want to hear from you. Join our team and apply your 15 years of experience to systems that truly matter.
This position requires U.S. citizenship and the ability to obtain and maintain a security clearance. Equal Opportunity Employer committed to building a diverse and inclusive team.
