PlayStation Global - Senior Data Scientist - Platform Economics & Simulation
Requirements
• You think in counterfactuals. You instinctively separate incremental effect from what would have happened anyway, and you reason naturally about substitution, cannibalisation, and the economics of a content platform. A background in economics, econometrics, or a similarly causal quantitative discipline is a strong fit. • Proven industry experience turning causal and economic understanding into decisions that changed commercial outcomes, in areas such as customer value, retention, pricing, or decisioning. • Depth in causal methods used to explain and understand systems: treatment-effect estimation, uplift, structural or counterfactual reasoning • The ability to build, not just analyse: you can implement models, simulation, or offline-evaluation environments and take them to production. • Strong judgement on when a sophisticated approach is warranted versus a simpler one that answers the question. • Experience owning ambiguous problems end-to-end: framing the question, choosing the approach, and delivering something the business acts on. • Fluency with large, complex behavioural datasets and the craft to work with them at scale: Python, SQL, and distributed processing (e.g. PySpark), plus standard ML tooling as the work requires. • Excellent stakeholder communication: you can make a rigorous causal argument land with a non-technical commercial audience and move a decision. • A strong quantitative academic background, typically a Master's or PhD. • Experience with incrementality and uplift modelling, or with experimentation frameworks. • Reinforcement learning or contextual-bandit decisioning, and offline evaluation for recommendation or decisioning systems. • Background in gaming, e-commerce, or subscription businesses. • Experience deploying and maintaining business-critical or consumer-facing models. • Experience working in agile, fast-paced environments. • Please note, Sony Interactive Entertainment conducts background checks at the offer stage for all new employees (which may include criminal background checks for some roles) and will need to process personal information to support these checks. • Please refer to our Candidate Privacy Notice for more information about what personal information we collect, how we use it, who we share it with, and your data protection rights. • Equal Opportunity Statement:
Responsibilities
• Explain why value moves across revenue, retention, and engagement, through value decomposition, cannibalisation and substitution analysis, meta-analysis across our models, and clear strategic trade-off framing. • Build offline policy evaluation and simulation tooling that lets the platform identify the content, players, and policies that create incremental value, and stress-test decision policies before they scale. • Guide model development across the team, raising the standard of causal and economic thinking through review, mentoring, and example. • Turn causal understanding into concrete proposals, and respond with rigorous answers when the platform needs them. • Communicate assumptions, methods, and conclusions clearly enough that senior technical and commercial audiences can act on them with confidence.
