Hybrid

We believe that through collaboration and connection with our colleagues we can achieve great things. Our hybrid working approach allows our people to work both in the office and at home, providing the flexibility and resources you need to succeed in your role. We don't require you to be in on specific days; instead, we ask people to come into the office 2-3 days each week, for at least 8 days per month. You should work with your line manager to understand what their expectations are for you, your specific role and your team.

We're creating more than the UK's best network. We're helping close the digital divide, empower communities and drive meaningful progress.

We believe that everyone should feel they belong. Whoever you are and whatever your story, there's space for you here. We're building a workplace where different perspectives are welcomed, voices are heard, and everyone feels safe to show up as themselves.

You'll join a team that genuinely cares - about each other, about our customers, and about the future we're building. From day one, you'll be welcomed, valued and encouraged to bring your whole self to work.
