Job summary

Sony Interactive Entertainment is seeking a Data Scientist to develop ML models for churn, purchase propensity, and lifetime value to drive player engagement and monetisation across the lifecycle.

You will work with cross‑functional teams to translate business problems into modelling approaches, validate insights, and deliver scalable solutions that inform product and commercial decisions.

Qualifications

• Experience building predictive models (e.g. churn, propensity, segmentation, or value modelling) in a commercial setting.
• Ability to independently take a problem from definition through to solution and delivery.
• 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).
• Strong communication and collaboration skills with cross-functional stakeholders.
• Awareness of modern ML approaches (e.g. embeddings, sequence models, deep learning).
• Experience working with large datasets to generate actionable insights.

Responsibilities

• Own the development and delivery of machine learning models for churn prediction, purchase propensity, store recommendations, and CLV.
• Translate business problems into modelling approaches and select methods and features.
• Work with large-scale behavioural and transactional data to uncover patterns and opportunities.
• Collaborate with engineering, product, and commercial stakeholders to ensure robust and scalable solutions.
• Partner with stakeholders across commercial, finance, and lifecycle teams to support data-driven decision-making.
• Clearly communicate findings to technical and non-technical audiences.
• Develop and expand understanding of advanced modelling approaches as problems grow in complexity.

Job description

Department Overview

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. You will work in cross‑functional teams to translate player behaviour into actionable strategies that drive measurable improvements in player engagement and value.

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.

What you’ll be doing

• Own the development and delivery of machine learning models for use cases such as churn prediction, purchase propensity, store recommendations, and customer lifetime value.
• Translate business problems into modelling approaches, selecting appropriate methods and features to deliver measurable impact.
• 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.
• Clearly communicate findings and recommendations to both technical and non-technical audiences.
• Develop and expand your understanding of more advanced modelling approaches (e.g. deep learning and sequence-based methods) as part of solving increasingly complex problems.

What we are looking for

You’re curious, analytical, and a strong problem‑solver, with a structured approach to tackling business problems. 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.
• Ability to independently take a problem from definition through to solution and delivery, demonstrating initiative and ownership.
• 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.
• Strong communication and collaboration skills, with the ability to clearly articulate insights and work effectively with cross‑functional stakeholders.
• Awareness of modern machine learning approaches (e.g. embeddings, sequence models, deep learning) and interest in applying them to real-world problems.
• Experience working with large datasets to generate actionable insights.
• A strong academic background, typically a Master’s or Ph.D. in a quantitative or technical field (e.g. Mathematics, Statistics, Computer Science).

Nice to Have

• 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.

Benefits

• Discretionary bonus opportunity
• Private Medical Insurance
• Dental Scheme
• 25 days holiday per year
• On Site Gym
• Subsidised Café
• Free soft drinks
• On site bar
• Access to cycle garage and showers
