Network Infrastructure Engineer with Security Clearance

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

Salary: $80,000 – $90,000 | Clearance Required: Active Top Secret (SCI Preferred) ABOUT OSAAVA SERVICES

OSAAVA Services is a Service-Disabled Veteran-Owned Small Business (SDVOSB) specializing in Space, Cybersecurity, and IT Service Management for the U.S. government and defense community. We support mission-critical programs where performance isn't optional — and we build teams that reflect that standard. POSITION OVERVIEW

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.
