Data Scientist in London

We are the people behind global loyalty currency, Avios, and home to two ambitious, growing businesses across Loyalty and Holidays. Each business has its own goals, strategy and team, but collectively we share a purpose to create the world's most rewarding experiences for our customers through loyalty programmes, new products and holidays.

We are looking for a Data Scientist with a few years of industry experience to join our team working on customer data. This role is ideal for someone who enjoys combining hands-on machine learning with exploratory analysis, data visualisation, and business problem-solving. You will work closely with stakeholders to uncover meaningful insights, build predictive models, and help shape the future of our data and machine learning capabilities.

You will develop, evaluate and deploy machine learning models to support customer engagement, retention, churn prediction, and cross-sell and up-sell use cases. Alongside this, you will create clear and compelling visualisations and analytical outputs to communicate insights effectively to both technical and non-technical stakeholders. Your work will span a range of projects, from hands-on data science and modelling to more analytical and self-serve initiatives.

You will work closely with engineers, analysts and business teams to translate business questions into practical data solutions, while maintaining high standards of data quality, validation and documentation throughout the delivery lifecycle. You will also contribute to improving data science best practice, tooling and ways of working, and show a strong interest in developing your machine learning engineering skills, including model deployment, monitoring and scalability.

We are aiming high, and we accept that it is unlikely that any one person will meet every aspect of the brief. Who you are is equally as important as what you have done or where you have worked. So even if you don’t tick every box, or your experience is from a unique or varied background, we’d still love to hear from you!

Our vision, 'to create the world's most rewarding experiences,' applies not only to our customers but for our colleagues too. It’s about taking belonging seriously, actively fostering a culture where everyone feels welcomed and valued by embracing diverse identities, personal histories, and perspectives. This commitment makes IAG Loyalty a rewarding place to work and enhances our ability to solve complex problems, drive innovation, and better serve our customers and communities.
