Network Engineer - Juniper Focused

Job Description

The Network Operation Centre (NOC) has three main roles:

• to ensure maximum possible service availability and performance
• to provision customer network services on core equipment

These result in a highly diverse range of duties for the NOC – our engineers are required to ensure they are fulfilled in a timely, co‑operative and professional manner.

We interact frequently with technical support, service provisioning and sales teams so it's important that we are clear and concise in our communications.
