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. The Vinted Group is made up of three business units that support this mission: Vinted Marketplace is Europe’s leading platform for second-hand fashion and a go-to destination for all kinds of pre-loved items, with a growing range of categories. Our platform connects millions of members across 20+ markets, helping great items find a new life. Vinted Go enhances the shipping experience with a vast network of over 500,000 pick-up and drop-off points, partnering with more than 60 carriers across Europe, with added services like item verification for peace of mind on high-value pieces. Vinted Pay is the newest part of the Vinted Group, dedicated to bringing secure, reliable payments to buyers and sellers across Europe. Seamlessly integrated into the Vinted app, it helps keep every transaction safe, efficient, and easy for our members. Founded in 2008 in Lithuania, Vinted began as a way for friends to find new homes for clothes they no longer needed. In 2019, we became Lithuania's first unicorn! Today, our headquarters remain in Vilnius, and we've grown with offices across Europe, supported by a team of over 2,000 people. Information about the position The Buyer Domain at Vinted is dedicated to creating a seamless, delightful, and highly engaging experience for our members as they search, discover, and purchase items. Our challenge is unique: unlike standard e-commerce, our peer-to-peer catalog consists of hundreds of millions of entirely unique, single-inventory listings, with millions of new items uploaded daily. Connecting the right buyer with the perfect item in real-time is at the very core of Vinted's success. To tackle this challenge at scale, we are looking to bring talented Data Scientists into the Buyer Domain's two highly specialized, ML-focused teams: • Search Relevance: This team is responsible for the retrieval and ranking systems that power search queries across all markets. Their mission is to ensure our members can effortlessly find exactly what they are looking for in Vinted's vast, unique catalog. The team's ownership and focus areas include multi-stage search ranking pipelines, query intent classification, semantic dense retrieval, and the integration of ML relevance models with content policy controls, all optimized for real-time execution. • Recommender Relevance: This team owns the Recommender System that powers Vinted’s Homepage Feed and which is responsible for driving a significant portion of all discoveries and purchases across the platform. Their mission is to inspire our members by surfacing highly personalized, engaging, and relevant recommendations. The team's ownership and focus areas include deep sequence-based user modeling, real-time candidate generation and ranking, and exploration of diverse member interests, built to handle massive scale and high-throughput constraints. We will work with you to match your background, technical interests, and experience with the team where you can drive the most impact. Regardless of the team you join, you will be a proactive product partner. We work in a highly collaborative culture to align on technical approaches, and we validate all changes through rigor
