Our role at SIE is to create and nurture the experiences under the PlayStation brand, a name synonymous with entertainment excellence and creativity.

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 the drivers of long‑term player value and enabling better business decisions through robust forecasting and insight generation.

What you’ll be doing

• Apply causal inference methodologies to measure the incremental impact of player experiences, lifecycle interventions, product features, and commercial initiatives on Customer Lifetime Value (CLV).
• Design, analyse, and interpret experiments, quasi‑experiments, and observational studies to answer strategic business questions.
• Support the development of frameworks for measuring incremental CLV, uplift, and causal impact across acquisition, engagement, retention, and monetisation initiatives.
• Work with cross‑functional teams and business stakeholders to identify opportunities where causal measurement can improve decision‑making and resource allocation.
• Analyse large‑scale behavioural and transactional datasets to uncover drivers of player value and quantify their causal impact.
• Apply techniques such as propensity score matching, difference‑in‑differences, causal forests, and broader synthetic controls where appropriate.
• Collaborate with data scientists, analysts, and engineers to operationalise causal insights and embed them into decision‑making processes.
• Translate complex analyses into clear and actionable recommendations for both technical and non‑technical audiences.
• Contribute to the evolution of PlayStation’s CLV framework by incorporating causal approaches to understanding long‑term player value.

• Strong problem‑solving skills and a structured approach to tackling data challenges.
• A strong academic background, typically a Master’s or Ph.D. in a quantitative or technical field (e.g. Mathematics, Statistics, Economics, Econometrics, Computer Science, or a related quantitative field).

Nice to have

• Familiarity with modern causal machine learning techniques such as Double Machine Learning, Causal Forests, Meta‑Learners, and Uplift Models.
• Experience evaluating incrementality, or uplift using experimental data.
• Knowledge of Bayesian methods for causal analysis and decision‑making.
• Experience in gaming, e‑commerce, or subscription‑based products.
• Experience working with large‑scale data using PySpark or equivalent distributed data processing tools.
• Familiarity with production environments, MLOps, or data pipelines.
