Required Qualifications: 
  • Clearance & Polygraph: Active TS/SCI security clearance; willing to take a Counterintelligence (CI) Polygraph. 
  • Experience: 10+ years of network engineering experience, with a heavy focus on data center networking technologies and independent project management.

  • Routing & Network Protocols: SME-level expertise with dynamic routing protocols (OSPF, BGP) and TCP/UDP application flow analysis using built-in diagnostic tools and external analyzers. 
  • Tools & Documentation: Proficiency with MS Visio for network architecture mapping; strong written and verbal presentation skills.
Preferred Qualifications: 
  • Expert Certifications: CCIE, F5-CSE, or JNCIE.
