• Ensure internal and customer‑facing networks meet performance, security, and reliability standards.
• Advise clients and stakeholders on networking best practices and improvement opportunities.

• Minimum 5 years’ commercial experience in traditional networking (routing, switching, firewalls, security).
• In-depth knowledge of TCP/IP, DNS, VPNs, WAN/LAN, and routing protocols (OSPF, BGP, etc.).
• Strong experience and comfort working with Cisco IOS CLI.
• Familiarity with a variety of networking vendors (Dell, HP, Forti Gate, Ubiquiti, etc.).
• Proven experience working with:
  • Cisco SD‑WAN
  • Cisco FMC & Firepower Threat Defence (FTD)
  • Cisco ASA Firewalls
  • Cisco Meraki MX/Security Appliances
  • Cisco Nexus & Catalyst Switches
• Familiarity with managing configuration backups, log analysis, and alerting tools.
• Ability to diagnose and resolve complex network issues under pressure.
