Location: On-site (Customer Location)

Position Summary: 
The Senior Network Engineer delivers Tier III SME-level support across customer Data Center networks, application delivery platforms, and network security environments.

Key Responsibilities: 
  • Data Center O&M & Architecture: Perform Tier III troubleshooting, maintain LAN/WAN configurations, execute network upgrades, and evaluate emerging technologies for ERB presentation and integration. 
  • Deployment & Stage Management: Collaborate with cross-functional system engineers, project managers, and stakeholders to design, deploy, and scale network solutions on established timelines. 
  • Security & Performance Management: Ensure network integrations comply with DoD STIGs and customer standards; integrate systems into availability frameworks and execute change management protocols. 
  • Analysis & Diagnostic Operations: Perform complex TCP/UDP application flow analyses using network analyzers; coordinate with vendor/Tier IV support to resolve hardware/software anomalies. 
  • Documentation & Standard Operating Procedures: Develop SOPs, network architecture diagrams, and troubleshooting procedures to standardize O&M workflows and support team operations.
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. 
  • Certifications: Professional or expert-level certification required (minimum CCNP, F5-CTS, or JNCIP). 
  • 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.
