Join us in our mission to transform the way people shop and eat, where impact, innovation and growth drive everything we do. Our Analytics organisation sits at the heart of Deliveroo, powering decision making across product, commercial and operations through experimentation, causal inference and machine learning.

• Master Causal Inference: Apply advanced techniques to estimate long term and heterogeneous treatment effects.

• Drawing reliable conclusions in settings with selection bias or imperfect randomisation.

• Drive Deep Product Insights: Uncover the fundamental drivers of experiment performance, determining why features succeed and how results generalise across different users, markets, and timeframes.

• Using insights from past experiments to improve future decision making.
