At PlayStation, Data Science plays a critical role in shaping how we invest in, retain, and delight our global player base. The CLV team focuses on understanding player behaviour and driving more effective engagement across the player lifecycle — from acquisition and onboarding through to retention, monetisation, and long-term value. As a Data Scientist, you will develop models and insights that help drive more personalised player experiences and inform commercial and product decisions at scale.

This role is ideal for an individual who is comfortable owning problems end-to-end — from framing and modelling through to delivering impact — and partnering with stakeholders to support data-informed decision-making.

• Own the development and delivery of machine learning models for use cases such as churn prediction, purchase propensity, store recommendations, customer lifetime value.
• Work with large-scale behavioural and transactional data to uncover patterns and opportunities for player growth and engagement.
• Collaborate within cross-functional teams, including engineering, product, and commercial stakeholders, to ensure solutions are robust, scalable, and aligned with business needs.
• Partner with stakeholders across commercial, finance, and lifecycle teams to support decision-making with data-driven insights.

You bring strong foundations in modelling and data manipulation, and are motivated by applying these to impactful, commercial problems:

• Experience building predictive models (e.g. churn, propensity, segmentation, or value modelling) in a commercial setting.
• Proficiency in Python and SQL, and familiarity with common data science and ML libraries.
• Solid understanding of machine learning techniques (e.g. regression, tree-based models, clustering) and when to apply them, including how to refine and tune them for real-world problems.
• Awareness of modern machine learning approaches (e.g. embeddings, sequence models, deep learning) and interest in applying them to real-world problems.
• A strong academic background, typically a Master's or Ph.D. in a quantitative or technical field (e.g. Mathematics, Statistics, Computer Science).
• Familiarity with production environments, MLOps, or data pipelines.
• Experience working with large-scale data using PySpark or equivalent distributed data processing tools.
• Experience in gaming, e-commerce, or subscription-based products.
