The Senior Managed Services Engineer is responsible for the delivery, operation, and continuous improvement of RISE’s managed services portfolio - starting with managed firewall (Fortigate) and expanding into managed SD-WAN and broader security services. Working within the Network Operations team, this senior technical role will operate customer-premises and cloud-managed equipment, act as the senior escalation point for managed services customers, and partner with the Network Design team to productise and lab-test new managed offers. This is a hands-on, client-facing role that combines deep network security engineering with service delivery discipline. The successful candidate will help to shape the operating model, tooling, and documentation that define how RISE delivers managed services at scale.
