Job description

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
• to provide support services for Engineering and other technical teams

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.

We also work very closely with the Engineering team and as such need to develop a good all‑round understanding of systems and networks.

Diligence and attention to detail are also key skills along with an ability to multi‑task and prioritise work appropriately.

We don't expect you to have all the required knowledge when you join us as many of these skills can be picked up through experience in the job, but those who do need to learn new skills must be prepared to spend time doing suitable research to ensure their grounding is thorough and properly understood.
