Our Values

Five shared commitments shape how we work, and how we will work with you:

• Value Every Voice. We put people first.
• Act with Integrity. We do what is right.
• Explore Beyond Boundaries. We are driven by curiosity.
• Own the Outcome. We take responsibility for our decisions.

The Role

This is applied data science. You will use advanced analytics and machine learning to understand our customers better and solve problems that genuinely matter to the business, working with customer, booking, digital, marketing and behavioural data.

You will work across segmentation, propensity, personalisation, retention, forecasting and customer lifetime value, with the space to explore and the support to grow.

• Explore complex behavioural and transactional data to find what others have missed.
• Develop and evaluate statistical and machine learning models.
• Build segmentation, propensity, forecasting and personalisation solutions that reach real customers.
• Apply rigour to feature engineering, validation and model performance.
• Design and evaluate experiments to understand genuine impact.
• Work with Data Engineering to create reliable model inputs and productionise valuable solutions.
• Monitor solutions in the wild and keep improving them.
• Communicate findings clearly to both technical and business audiences.
• Contribute to data science standards, reproducibility and responsible AI practice.
