At Apple, some of the most important decisions are shaped by the quality of the evidence behind them. We are seeking a Senior Data Scientist, Experimentation & Causal Inference to help advance the scientific foundations of measurement, experimentation, and organizational learning across Apple Services.

This role sits at the intersection of statistics, causal inference, experimental design, and decision-making. You will help define how success is measured, how experiments aredesigned, and how causal evidence is generated and accumulated across the organization.

Beyond individual experiments, you will help build the next generation of experimentation intelligence by transforming isolated experiment outcomes into reusable scientific knowledge. As Apple expands investments in AI-powered experiences and intelligent systems, this role will also help evolve the experimentation methodologies used to evaluate increasingly complex product behaviors and long-term user outcomes.

The ideal candidate combines deep statistical expertise with strong scientific curiosity and a passion for developing rigorous methodologies that improve how organizations learn and make decisions at scale.

Description

As a Senior Data Scientist, Experimentation & Causal Inference, you will own key components of the experimentation science ecosystem. You will work across product, growth, engineering, data engineering, and strategic science teams to define measurement frameworks, experiment methodologies, statistical standards, and causal inference approaches that improve organizational decision quality.

This role extends well beyond traditional A/B testing. You will help establish experimentation standards, develop advanced causal methodologies, build experimentation intelligence systems, and drive cross-experiment learning initiatives. You will play a critical role in ensuring that experimentation generates reliable evidence, scalable insights, and reusable scientific knowledge.

This includes helping establish experimentation approaches for emerging product paradigms where user interactions, adaptive systems, and long-term outcomes introduce new measurement and causal inference challenges.

The ideal candidate possesses strong expertise in experimental design, causal inference, statistical modeling, and scientific reasoning. Experience with modern causal machine learning techniques, heterogeneous treatment effect estimation, meta-analysis, and experimentation intelligence systems is highly desirable.","responsibilities":"Experiment Design & Measurement Strategy
