Network Infrastructure Engineer

53rd Wing Support Contract | Eglin AFB, Florida | Full-Time | On‑Site

Salary: $80,000 – $90,000

Clearance Required:

Active Top Secret (SCI Preferred)

OSAAVA Services is seeking a Network Infrastructure Engineer to support the 53rd Wing at Eglin AFB, Florida. This is a hands‑on, technically demanding role for a professional who has designed, implemented, and maintained enterprise‑level network infrastructures in DoD or similarly complex environments.

The right candidate brings deep experience with Cisco networking equipment, firewall administration, and Windows Server environments – and can operate independently in a fast‑paced, mission‑focused setting where network availability directly impacts operational readiness.

This is not a helpdesk or junior systems administrator role. We are looking for someone who has built and sustained infrastructure, not just supported it.

• Design, implement, and maintain enterprise‑level LAN/WAN network infrastructure supporting 53rd Wing operations
• Configure, administer, and troubleshoot Cisco routers, switches, and firewall platforms in classified and unclassified environments
• Manage and maintain Windows Server environments including Active Directory, Group Policy, DNS, and DHCP
• Administer and maintain firewall rule sets, ACLs, VLANs, and network segmentation configurations
• Monitor network performance, diagnose complex connectivity and infrastructure issues, and implement corrective actions
• Ensure all systems remain compliant with STIG requirements, DISA standards, and applicable DoD security policies
• Coordinate with cybersecurity personnel on vulnerability remediation, RMF compliance, and system hardening
• Maintain comprehensive network documentation, configuration records, and change management logs
• Support lifecycle management of network hardware, servers, and endpoint systems
• Respond to and resolve IT infrastructure tickets; elevate complex issues appropriately

• Active Top Secret clearance (required at time of application)
• 3–7 years of hands‑on experience designing, implementing, and maintaining enterprise network infrastructure
• Proven, documented experience configuring and administering Cisco routers, switches, and firewall platforms in a production environment
• Proficiency with Windows Server environments (Active Directory, DNS, DHCP, Group Policy)
• CompTIA Security+ (IAT Level II compliant) – required
• Experience working in a DoD, U.S. Air Force, or equivalent federal IT environment
• Strong troubleshooting skills across network hardware, infrastructure, and systems layers
• Ability to work on‑site at Eglin AFB, FL

• TS/SCI clearance
• CCNA or equivalent Cisco certification
• Experience with firewall platforms including Cisco ASA, Palo Alto, Fortinet, or equivalent
• Experience with STIG implementation and RMF/ATO compliance
• Familiarity with ITSM/ticketing platforms (Remedy, Service Now)
• Experience supporting USAF Wing‑level operations or comparable DoD command environment
• Experience with endpoint management tools (MECM/SCCM)
• Experience with network monitoring tools (Solar Winds, Splunk, ACAS/Tenable)

• Medical, dental, and vision insurance
• 401(k) with company match
• Paid time off (vacation, sick leave, holidays)
• Professional development and certification support
• Life and disability insurance
