Job description

The ad as published by the employer.

As a Decision Scientist in the Search Relevance team within the Buyer domain, you will partner with Data Scientists, Engineers, and a Product Manager to improve how members search our catalog and maximize buyer conversion. The Buyer domain is organized across three layers of product teams: the Experience layer (Discovery & Rediscovery, Search & Refinement), the Content layer (Search Relevance, Recommender Relevance, Content Visibility Management), and the Platform layer (Search Platform, Content Visibility Platform). Together, these teams ensure members find relevant items effortlessly across millions of unique second-hand listings. Within Search Relevance, our scope spans the entire search journey: from semantic and keyword retrieval (including Dense Retrieval vector search) to multi-stage ML ranking (pre-ranking, deep reranking, and personalization). In this role, you will collaborate with your Product Manager, a senior Decision Scientist, and the engineering team to lead analytical discovery, identify search friction and opportunity areas, define success metrics, and design and evaluate A/B experiments measuring the business and member impact of our ranking and retrieval algorithms. You will also be part of the Buyer Decision Science community, collaborating quarterly on technical standards, domain-wide analyses, and experimentation capabilities. Additionally, you will participate in Vinted's company-wide Data Science & Analytics (DSA) guild, which regularly hosts knowledge-sharing sessions, workshops, and off-sites.
