• Serve as a Tier 3 escalation point, troubleshooting and resolving complex network issues
• Configure and support routers, switches, firewalls, VPNs, wireless controllers, and related infrastructure
• Work across technologies from Cisco, Meraki, Fortinet, Juniper, Sophos, Aruba, Ubiquiti, and other leading vendors
• Support and optimize routing protocols including BGP, OSPF, and EIGRP
• Work with VLANs, STP, SD-WAN, VPN technologies, and cloud networking environments
• Monitor network performance and identify opportunities to improve performance, security, redundancy, and resiliency
• Develop network diagrams, technical documentation, and standard operating procedures
• Mentor junior and intermediate engineers and provide technical leadership across the team
• Partner directly with clients and internal teams to translate business requirements into effective technical solutions
• Participate in an on-call rotation supporting business-critical client environments
