• Monitor and support optical transport, IP/MPLS networks (including vendor-specific platforms), and connectivity services into cloud environments (e.g., ExpressRoute, DirectConnect).

• Work collaboratively with other functions (e.g., operations, cloud, security) to ensure holistic service availability and reliability across the network.

• Provide written and verbal updates to stakeholders on incident status, resolutions and performance metrics.

Required experience/skills:

• A degree in Telecommunications, Information Technology, Computer Science or a closely related discipline, or equivalent experience.

• Hands-on experience using network monitoring tools and ticket-management systems.

• Strong understanding of TCP/IP and fundamentals of routing and switching.

• Proficiency in LAN and WAN troubleshooting, including cabling, equipment and facility issues.

• Working knowledge of IP/MPLS networks (experience with vendor platforms such as Juniper MX series is a plus).
