You’ll play a critical part in supporting and evolving services that underpin O2 Business and wider VMO2 customers, working across core network and hosted voice environments.

You’ll be hands-on with provisioning, fault diagnosis, software upgrades and complex incidents, while also contributing to change delivery and new product development. Working closely with engineering, test, delivery teams and third party partners, you’ll help ensure our services are resilient, secure and ready for the future, including participation in a 24x7 on call rota.

Who we are

At Virgin Media O₂, we connect people to the moments that matter most. Virgin Media leads the UK for broadband reliability, speed and overall performance, while O₂ keeps people connected on the move with award-winning coverage.

We’re also proud to be named one of the Financial Times Top 500 Best Employers for 2026, based on one of the UK’s largest employee satisfaction surveys.

Join us and you’ll be part of a team that stays curious, positive and focused on making life easier for our customers and each other. We’re investing in the future of connectivity, from expanding next-generation 5G to exploring satellite-supported solutions that help reach rural communities and hard-to-connect places. 

You’ll work with people who back good ideas and give you plenty of room to grow. So if you’re looking for a place where you can feel supported, trusted and genuinely valued, you’ll feel right at home here.

Our ways of working

We’re a flexible-first organisation, because we know people do their best work when they have choice and clarity. To support meaningful collaboration, we ask everyone to spend at least eight days a month connecting with each other in person.

That doesn’t just mean time in the office – it could be team meetings, offsites, volunteering days, cross-functional projects, or away days. What matters is making those moments count – so when we come together, it benefits everyone.

Accessible, inclusive and equitable for all 

We believe a better tomorrow starts with the choices we make today. That means moving the dial on diversity, building equity into everything we do and putting inclusion at the heart of our business.

Virgin Media O₂ is an equal opportunities employer and we work hard to remove bias and barriers. We want every person who joins us – and everyone thinking about joining us – to feel seen, heard and supported.

When you work with us, you’ll have access to our award-winning employee network groups. These communities bring people together, champion allyship and create uplifting spaces where you can learn, share and feel part of something bigger. They play a big role in helping people feel connected from day one
