# Senior Data Scientist, Delivery Consumer Discovery

Job Description We’re looking for an experienced Data Scientist to own the ranking and recommender systems behind how customers discover what to order on Bolt Food. Your work shapes what each customer sees first on the home screen and across other personalised surfaces, and you’ll take ideas from research all the way into production. About us With over 200 million customers across 50+ countries and 850+ cities, Bolt is one of the fastest-growing tech companies in Europe and Africa — powered by 4.5+ million partners on our platform, 4,000+ employees globally. And it's all thanks to our people. We believe in creating an inclusive environment where everyone is welcome, regardless of race, colour, religion, gender identity, sexual orientation, national origin, age, or ability. Our ultimate goal is to make cities for people, not cars — and we need your help on this mission! About the role You will work on the core systems that help customers find the right restaurants, stores, dishes, and items across Bolt Food. Your initial focus will be the home screen and other personalised screens: which categories and carousels each customer sees, in what order, and what appears within them.
