Job Description & How to Apply Below
Position Summary
This is an individual contributor role requiring deep, dual-OS engineering expertise across both Linux and Windows Server platforms, alongside heavy enterprise virtualization (VMware). The ideal candidate is a mission-focused technical expert—such as a prior military communications or IT specialist—who thrives in high-pressure, "no-fail" DoD environments and is passionate about scripting, infrastructure automation, and security compliance.
Note:
This is a 90% hands-on technical engineering role, not a management position. Critical Eligibility Criteria (Day-One Requirements)
Clearance:
Active DoD SECRET clearance or higher (Interim clearances cannot be accepted). Cybersecurity Compliance:
Current DoD 8570 IAT Level II certification (e.g., Security+, CASP+, CISSP).
Experience:
Minimum of 8 years of hands-on systems administration/engineering experience in enterprise environments.
Education:
Bachelor’s or Associate’s degree in Engineering, Computer Science, Information Systems, or a related technical field. Core OS Expertise:
Proven, deep engineering capability in both Linux (RHEL/CentOS) and Windows Server environments (candidates with only single-OS experience will not be considered). Virtualization:
Daily, production-level experience administering VMware vSphere, ESXi, and vCenter. Automation:
Strong shell scripting skills (Bash/Power Shell/Python) with the ability to build automation scripts from scratch. Availability:
Must be willing and able to participate in a 24/7 on-call rotation (approximately 1 week per month for occasional mission-critical incidents).
Key Responsibilities
Security & Vulnerability Patching:
Install Information Assurance Vulnerability Alerts (IAVAs) across 100+ distributed servers. Run monthly ACAS/Nessus security scans and execute remediation findings. Virtualization Management:
Manage the full lifecycle of VMs (provisioning, cloning, snapshots, migrations) across a large-scale VMware footprint, utilizing vSphere 6.x/7.x and vCenter. System Operations:
Manage SSL certificate life cycles, deploy Data Alignment Packages (DAPs) to NTCSS systems, and generate Requests for Comments (RFCs) for system changes and resource allocations. Automation:
Author custom Bash and Power Shell scripts to automate repetitive administrative tasks and streamline continuous integration pipelines. Fleet Support & Incident Response:
Troubleshoot complex, tier-3 infrastructure and connectivity issues affecting global fleet operations (ships, subs, and shore stations), responding rapidly to datacenter outages. Compliance Maintenance:
Maintain strict Host Based Security System (HBSS/Trellix) endpoint compliance across the infrastructure.
Collaboration:
Participate in daily Scrum standups with the Prod Ops team, collaborating closely with developers and Tier-2 support. Technical Environment & Requirements
Operating Systems:
Linux/Unix: RHEL, CentOS, Ubuntu (Expert-level package management, service management, systemctl, cron, user/group management). Windows Server: 2008–2019 (Active Directory, Group Policy, Power Shell, IIS). Virtualization: VMware vSphere 6.x/7.x, ESXi host configuration, vCenter management, performance tuning. Security & Compliance: ACAS/Tenable/Nessus, STIG implementation/validation, HBSS/McAfee/Trellix, certificate management. Networking Fundamentals: TCP/IP, DNS, DHCP, routing, firewall rules, port management, network troubleshooting tools (ping, trace route, netstat, tcpdump), and load balancing.
Database (Basic Operations):
Sybase (highly preferred) or any relational database. Ability to perform backup/restore operations and execute basic SQL queries for troubleshooting connectivity.
Preferred Qualifications & Differentiators
Prior Military Service:
Strongly preferred, particularly US Air Force or US Navy IT/communications fields (e.g., Navy IT, ET, or Air Force Comm). NTCSS Knowledge:
Prior experience with NTCSS system administration or Navy logistics applications (R-Supply, OOMA, NALCOMIS) is a massive differentiator. Scaled Virtualization:
Experience managing large-scale VMware environments consisting of 100+ hosts and 500+ VMs. Navy Networks:
