The Data Scientist at Virgin Media will play an important role in developing predictive models, analysing complex datasets, and supporting the delivery of data‑driven products that drive value across the business. This role sits within our fraud and credit risk domain, where you will help build and maintain models that detect fraud, assess customer risk, and strengthen decision‑making for critical business processes.

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.

You’ll be part of our Data Science organisation, which creates data products that provide Virgin Media with competitive advantage. We apply statistics and machine learning to uncover insights, enable risk‑based decisioning, and automate processes across the business.

In this role, you will support the development, monitoring, and improvement of models used in credit risk assessment, fraud detection, and responsible customer decisioning. You will also contribute to data exploration, feature development, and analysis that helps shape risk strategies, reduce losses, and ensure Virgin Media is protected from emerging fraud threats.

You will help maintain the predictive models and segmentation tools that feed core business infrastructure, ensuring they remain accurate, reliable, and compliant.
