  • Strong working knowledge of routing/switching protocols (BGP, OSPF, EIGRP, MPLS) and network management tools (Solar Winds, Wireshark, Net Flow, SNMP).
  • Familiarity with DoD or government network environments, including RMF compliance and STIG hardening.
  • Proven ability to troubleshoot complex network issues in both lab and operational environments.
  • Certifications:

    Security+ to support firewall administrative privileges.

  • Current/Active Secret U.S. Security Clearance is required.
Qualifications We Prefer
  • Juniper SSR and VSRX experience.
  • Experience working with DoD tactical data/datalinks (JREAP, UCI, ASTERIX, VMF, VOIP, etc.).
  • Experience with network optimization / QoS to support edge‑based data distribution.
  • Entry‑level experience with software coding/scripting development to support simple applications.
Benefits
