If you’re looking to make an impact, bring your spark and be part of something meaningful – we’d love to have you on the team. 🌙🐷 Data Scientist | 📍London or Manchester – Hybrid (1–2 office days per week) | 💰Competitive Salary + Benefits About the Role We’re looking for a Data Scientist to join Moonpig, working hybrid from London or Manchester. You’ll build, evaluate and help productionise machine learning solutions that solve real customer and commercial problems across recommendations, personalisation, customer modelling and predictive modelling. This is a hands-on applied Data Science role where you’ll work closely with Product, Engineering, MLOps, Commercial and Marketing. You’ll turn clearly defined problems into practical ML solutions, evaluate whether they’re working and help bring them successfully into production. You’ll have the independence to make sound decisions within your problem space, while being part of a collaborative team that values high-quality, reproducible code and thoughtful experimentation. You’ll also use modern AI-assisted development tools responsibly to improve the speed and quality of delivery. Key Responsibilities Develop and evaluate machine learning models across recommendations, personalisation, customer and predictive modelling. Explore data, engineer useful features and compare modelling approaches, choosing solutions that fit the problem rather than adding unnecessary complexity. Partner with Product, Commercial, Marketing and other stakeholders to understand problems, clarify requirements and translate them into practical Data Science approaches. Apply appropriate offline model evaluation, investigate model behaviour and clearly communicate performance, limitations and trade-offs. Contribute to the design and analysis of A/B tests and other experiments, connecting model performance with customer behaviour and business outcomes. Develop solutions with production use in mind, partnering with Engineering and MLOps to integrate models into ML pipelines and support deployment, monitoring and ongoing improvement. Write tested, modular and maintainable Python and SQL, contributing to shared codebases and reproducible workflows using established software-development and version-control practices. Monitor deployed solutions and investigate model performance, data quality and unexpected behaviour, contributing improvements where needed. Use AI-assisted tooling across coding, analysis, exploration, experimentation and documentation, critically validating outputs to maintain quality. Take part in code and analytical reviews, share knowledge and contribute to reusable tooling, documentation and improvements to Data Science ways of working. About You Experience developing machine learning or advanced analytical solutions in a Data Science, Machine Learning or Advanced Analytics role. Strong practical understanding of supervised machine learning, feature engineering, validation, overfitting and model evaluation, backed by real-world modelling experience. Strong Python and SQL skills, with experience applying both to real-world data and modelling problems. Ability to translate defined customer or business problems into appropriate
