We have an amazing opportunity for a Senior Data Scientist to join our amazing team here at Virgin Media O2.

You'll play a major part in designing and implementing predictive models along with conducting detailed data exploration to improve business value & growth through the application of data science techniques. These predictive models created will feed critical business infrastructure, offering a fantastic platform to hone your machine learning skills with direct impact on business objectives. You will work as part of a high-performing data science and insight team with ownership of models and the modelling process in the wider modelling eco-system.

To be successful in this role, you'll be experienced in running and leading a team, but also hands-on and passionate about building the latest machine learning predictive models. You will also want to drive the end of goal of each project to ensure the application of each model is efficient for current business objectives. You'll also have strong skills in data manipulation which will enable you to navigate and leverage our significant data assets to build the optimal production models.
