- Sites & scale: local/office locations, multiple data centres, and cloud (AWS and OCI), including international and remote sites, some in PCI/SOC-regulated scope.
- Routing & switching: Cisco Nexus and IOS-XE/NX-OS platforms; OSPF, BGP, vPC, VRF, VLANs, and QoS.
- Security & edge: Palo Alto firewalls (Panorama), Global Protect VPN, DMZ/NAT, IPS/IDS, and web proxy.
- Wireless & access: Cisco wireless (WLC/AP), FortiNAC, Cisco ISE, and TACACS+/RADIUS.
- Connectivity: MPLS and IPsec WAN, cloud interconnects and partner VPNs, and DNS/DHCP.
- Tooling: SolarWinds, Cisco DNA Center, syslog/SIEM, Qualys, and ServiceNow (ITSM/CMDB).
- Monitor, diagnose, and resolve complex network incidents; lead P1 bridges to resolution.
- Plan, test, and implement changes under change control; manage device configs and firmware lifecycle.
- Build and validate firewall rules, NAT, and VPN within security and compliance guidelines.
- Perform root-cause analysis, drive problem management, and set technical standards for the team.
- Coordinate carriers and hardware vendors; manage TAC/support cases through to closure.
- Mentor and uplift frontline engineers; keep diagrams, runbooks, IP records, and the CMDB current.
- Partner on design, technology refresh, automation, and continuous improvement.
- 8+ years in enterprise network operations and engineering, including senior or lead-level responsibility on a multi-site, hybrid-cloud estate.
- Strong hands-on Cisco routing/switching (Nexus, IOS-XE) and Palo Alto firewall (Panorama) skills.
- Practical experience with cloud networking (AWS/OCI), enterprise WAN, Cisco ISE, and enterprise monitoring tools.
- Comfortable working within ITIL processes (incident, change, problem) in ServiceNow, and within PCI/SOC boundaries.
- Clear written and spoken English; able to lead a P1 bridge, mentor others, and write clean RCAs and runbooks.
- CCNP Enterprise required (or equivalent proven depth); CCIE (Enterprise Infrastructure or Security) strongly preferred.
- Palo Alto PCNSE and cloud-networking (AWS/OCI) credentials a plus.
