Full time 37.5 hours per week – Mon – Fri

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.

You should work with your line manager to understand what their expectations are for you, your specific role and your team.

We’re here to build a network the UK can count on – one that connects people, places and potential. Because no matter where you live, what your background is, or how you get online – we think everyone deserves the same chance to stay connected, and with Vodafone Three, that future’s being built – today. 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.

Join us and you’ll be at the heart of change. That means building responsibly, investing sustainably and creating opportunities that last. We’re not just expanding connectivity; we’re reimagining what a connected nation looks like. With £11bn invested in 5G and digital infrastructure, your work will directly power businesses, services, and communities across the country. You’ll work on real challenges, with real impact, across every corner of the country.

Wherever you join us, whatever your role, you’ll be helping to build a future that works better for everyone. We move at pace, because what we’re building matters – and we’re learning as we go. We’re proud of the progress we’ve made, but we’re just getting started. Join us at the heart of our business in Corporate, one of the central support functions that underpin our business and keep us moving forward.

We provide centralised support, expertise and guidance across our UK and Group operations, continuing to build on our success and trailblazing the way to our next stage of digital growth.
