This is an excellent opportunity for early‑career data scientists — including MSc/PhD graduates — to gain hands‑on experience building production‑grade models in a fast‑moving, high‑impact environment. You will work as part of a high‑performing data science & insight team, contributing to the wider modelling ecosystem and supporting the ongoing development of analytical capabilities across Virgin Media.

Virgin Media is delivering the biggest investment in UK digital infrastructure for over a decade, with a £3bn programme extending ultrafast broadband and Virgin TV services to millions of homes and businesses.

Who we are

The UK’s fastest broadband network. The nation’s best-loved mobile brand. And, one of the UK's biggest companies too. We put our customers first, making life simpler, smoother, and more joyful. With big ambitions and a brilliant team, we’re building a more connected future for everyone.

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 each month connecting 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 - anywhere meaningful collaboration happens. What matters is making those moments purposeful, so when we come together, it really counts.

Accessible, inclusive and equitable for all

Virgin Media O2 is an equal opportunities employer and we're working hard to remove bias and barriers for our people and candidates. So, we build equity and inclusion into everything we do, from the policies we craft to the relationships we shape. We support and encourage you to be your authentic self throughout your application journey with us.

The must haves

In order to be considered, you must have the following experience;

• Strong academic background in a STEM field (MSc or PhD preferred) or 1–2 years of commercial data science experience
• Experience applying ML techniques to real‑world datasets
• Practical experience with SQL and Python (numpy, pandas, scikit‑learn, matplotlib, etc.)
• Ability to work in a shipping/iterative product environment and contribute to continuous improvement
• Solid grounding in statistics, probability, and core machine learning concepts

The other stuff we are looking for

We'd also love you to bring;

• Curious, proactive, and comfortable exploring new methodologies and technologies
• Familiarity with A/B testing and experimentation

What's in it for you

Our goal is to celebrate our people, their lives and everything in-between. We aim to create a culture that empowers everyone to bring the best versions of themselves to work each and every day. We believe the most inclusive and diverse culture makes for a better business and a brighter world.

Working at Virgin Media O2, you get a bumper reward package bursting with benefits, and loads of extras you can add if you’d like to. These are designed to support both you and your loved ones, making sure that you’re covered no matter what life throws your way.

Next steps

If we feel like a place where you can belong, we'd love to learn more about you as a person and your experience to date. Once you've submitted an application the next steps of the process, if successful, are likely to include a two stage interview process including competency and technical stages.

When you apply, you'll be asked about any adjustments you might need to support the recruitment process. Let us know, and we'll be sure to discuss it with you.

Please note: Applications will be reviewed, and interviews conducted throughout the duration of this advert, therefore we may bring the closing date forward. We encourage all interested applicants to apply as soon as possible. If you’re offered a job with us, it will be conditional, based on the passing of background checks. All roles require a criminal record check and some roles need a financial probity check. Your recruiter can provide you with more information if needed.

Thanks for your patience and for showing an interest in joining the Virgin Media O2 family.
