Job Description

Job description:

We're looking for engineers with hands-on operational experience in large Cisco enterprise environments who can contribute with minimal ramp-up time.

Our current environment includes:

  • Cisco Software-Defined Access (SDA)
  • Cisco Catalyst Center (DNA Center)
  • Cisco Identity Services Engine (Client)
  • Cisco Catalyst 9800 Wireless Controllers
  • Cisco Catalyst 9130/916x Access Points
  • High-density enterprise and healthcare wireless
  • Cisco Nexus data center technologies, including VXLAN/EVPN and Nexus Dashboard (NDFC)
  • Cisco routing and switching
  • Cisco Secure Firewall technologies
  • Azure connectivity (ExpressRoute) and hybrid networking
  • ServiceNow change, incident, and operational workflows

From an experience perspective, we're looking for candidates who can demonstrate real-world operational ownership not just exposure. Strong candidates should be comfortable discussing topics such as:

  • Troubleshooting Cisco SDA fabrics and Catalyst Center
  • Cisco Client authentication, authorization, profiling, and endpoint onboarding
  • Enterprise wireless troubleshooting, RF optimization, roaming, and client performance
  • Routing protocols including BGP, OSPF, and EIGRP
  • Data center networking using VXLAN/EVPN
  • Large-scale Cisco switching and routing
  • Incident response and root cause analysis in a production environment
  • Working in a 24x7 operational support model with on-call responsibilities

Candidates whose experience is primarily limited to traditional routing and switching, data center deployments, or configuration work without hands-on experience supporting SDA, Catalyst Center, Client, and enterprise wireless typically are not the right fit for this role.

Healthcare experience is certainly a plus, but it isn't required. What's most important is experience supporting large, always-on Cisco enterprise environments where uptime, operational excellence, and troubleshooting are critical.
