 * Support Cisco ACI and enterprise routing and switching.
 * Configure and manage Fortinet network-security technologies.
 * Support Azure networking including VNets, NSGs and VPN gateways.

 * Monitor and improve network availability, performance and resilience.
 * Deliver network changes and projects alongside internal teams and external partners.
 * Identify opportunities for network automation and operational improvement.
