Senior Data Scientist

This London senior data scientist job follows a hybrid pattern of three days in the office. It belongs to Deliveroo's Data Science organisation, which guides decisions across the three-sided marketplace linking customers, restaurants and riders. Work happens across product, operations and platform teams, with the aim of making the company better at evidence-based choices and at reading its own data.

Several senior data scientist vacancies are open across the business. Instead of hiring for one set team, interviewers learn about each candidate's abilities, preferences and growth areas before matching them with a remit and squad.

Day to day, the data scientist spots and defines high-value questions tied to strategic goals and metrics, then delivers quality results with limited supervision. Vague problem spaces are structured into technical plans that sometimes cut across neighbouring systems. The person picks the most suitable technique for each job, plans measurement programmes from simple split tests to intricate designs, and applies causal inference when standard trials cannot be run. Contributions to the analytics community and to organisation-wide priorities are also expected.

Ideal candidates bring meaningful data science experience and a pragmatic approach centred on impact. They translate business questions into analytical problems, lead experiments of varied complexity, and communicate clearly through presentations, written documents and code. Working knowledge of R or Python and SQL is required, while experience with Cursor or other AI tools is a bonus. The company typically runs three or four interview stages.
