This is an opportunity to join a growing data science function at a pivotal point in its evolution.

With senior backing and investment in data, this is a role where your work will directly influence commercial decisions.

The Company

Data and analytics sit at the centre of their growth strategy, with clear investment into modernising CRM, marketing measurement, and decision-making capabilities. The data science team has expanded rapidly and continues to grow across the UK and US, with strong visibility and support from senior stakeholders.

The Role

  • Lead the development and evolution of media mix modelling to understand and optimise marketing channel performance.
  • Scale an existing UK marketing effectiveness model and support its rollout into the US market.

  • Familiarity with cloud environments such as AWS is beneficial.
