Being a Data Scientist is about so much more than working with numbers. It’s your chance to turn complex data into meaningful insight, build solutions that influence decisions and help Costa unlock new opportunities, which means you’ll be:

Creating and maintaining data pipelines and automated workflows, following agreed ETL and data governance processes.
Producing clear reports, dashboards and visualisations using tools such as Power BI to bring your findings to life.
Working with colleagues across Data, Technology and Revenue Growth Management to understand business needs and translate them into data-led solutions.
Presenting actionable insights and recommendations to technical and non-technical stakeholders, helping teams turn analysis into commercial value.
Exploring cutting-edge AI methodologies responsibly and identifying opportunities to improve processes, products and decision-making.
Contributing to timely project delivery, strong model quality, stakeholder satisfaction and production-level code quality.
