  • Administer Cisco Meraki SD-WAN/switching for branch and site connectivity; manage Meraki Dashboard, configure MX security appliances, MS switches, and maintain templates.
  • Own BGP and OSPF routing design and operations; manage peering relationships, route policy, prefix filtering, and troubleshoot complex routing issues.

  • Provide Tier III escalation support for LAN/WAN incidents; participate in on-call rotation with a target 15-minute response SLA for critical issues.

Wireless Infrastructure
  • Administer and maintain documentation of Ruckus wireless infrastructure, including access point deployment, controller management (SmartZone or cloud), RF planning, and SSID/VLAN policy configuration.
  • Troubleshoot wireless connectivity, RF interference, and roaming issues; conduct periodic wireless site surveys and capacity planning.
  • Maintain wireless security standards, including 802.1X/RADIUS integration, guest network isolation, and rogue AP detection.
Cloud Networking
  • Design, document, and manage AWS VPC architecture across a multi-account environment governed by AWS Control Tower, including subnet design (public/private/isolated), CIDR planning, and inter-VPC connectivity.
