• Strong knowledge of IPSec (including DMVPN and RRI) design, configuration, operation, and troubleshooting.
• Experience designing cloud‑based architectures in AWS, Azure, or GCP.
• Expertise in IP multicast design, configuration, operation, and troubleshooting.
• Ability to design and implement network solutions based on high‑level customer requirements.
• Extensive TCP/IP and routing knowledge (BGP, OSPF, ISIS, EIGRP, PIM, BFD).
• Experience with Customer Edge features such as Network Address Translation and VRRP/HSRP.
• Proven ability to create and maintain comprehensive documentation for all implemented solutions.
• Expert‑level troubleshooting and debugging skills.
• Experience evaluating vendor products (hardware, software, service provider).
• Knowledge of broadband service deployments (xDSL, Cable).
• Capability to design, plan, and coordinate network maintenance and installation windows.
• Hardworking, focused, thorough, and punctual.
• Ability to provide written and verbal presentations on technical topics to corporate peers and management.
• Experience supporting Tier1 and Tier2 environments.
• Self‑motivated; able to work independently or within a team environment with minimal instruction from management.
• Flexible to work required hours and provide on‑call support.

Desirable Skills

• Fortinet, Cisco, and/or Juniper certifications (NSE Level 4/5/6/7, CCIE/CCNP‑SP, JNCIE, JNCIP).
• Experience with AAA, Tacacs+, Radius, and CA/PKI.
• Experience with Voice over IP, Dial Services (Async/PPP, ISDN), Wireless services (CDMA, EVDO, GPRS, EDGE, 802.11b/g/n), Server Load‑Balancing (F5).
• Data Center design and support (Cisco Nexus, Arista, Juniper).
