Stellenbeschreibung:

Join to apply for the Senior Data Scientist, Buyer role at Vinted

Brief Info About Vinted

Our mission is to make second‑hand the first choice, and we're looking for people who want to help us get there. Every day, we work together to help our members buy and sell pre‑loved clothing and lifestyle items, giving each piece a second life – or even a third.

Information About The Position

Our team operates within the Buyer domain, the part of Vinted Marketplace that is concerned with the buyer‑side of the marketplace. We develop features that enable our users to find the items they will love, whether through directed search or serendipitous discovery. Buyer domain is divided into several subdomains, each of which is an autonomous product team with its own Engineering, Design and Data Science & Analytics (DSA) specialists. You’d join as a Senior member of either the Discovery or Search team within Buyer.

At Vinted, we have three distinct roles within DSA. We believe each role can make a similar business impact in different ways, and therefore our salary ranges are the same for all three roles. To understand your role within DSA context better, here are brief descriptions of each role we have in the department:
