Overview

This hybrid role offers a great balance of home and office working. You'll join your colleagues in your local office at least 2 days a week. Please note: There is an on-call rota and you will be required to support 24 x 7 callout cover.

As the UK's largest fibre-only network, and its only proven wholesale challenger, we're busy setting new standards for what digital infrastructure can and should be.

Designed from scratch for the internet, our network is greener, more reliable and ready for the future. The products we provide over it not only lead the market on speed, value and service, they help businesses to innovate, provide entire communities with a better foundation for their digital lives and support economic growth, locally and nationally.

What does that mean for you? The opportunity to make internet connections (and daily life) a whole lot better, for a lot of people!
