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.

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 We are looking for a Senior Backend Software Engineer to join our Cozy team - the group building Vinted’s Moderation Platform.

requirements around speed, traceability, and reliability. We help millions of users feel safe on Vinted. We manage complex live state using live, snapshotted, and projected data patterns at large scale. Following a recent modularization effort, we are refactoring legacy paths and breaking out key microservices while balancing tight performance limits with experimentation. With massive data volumes, our engineers work on making flows highly observable, debuggable, and safe to change. We operate as a strong, collaborative cross-functional product team: Web frontend engineers, four Backend engineers, a Software Engineer in Test (QA), and an EPDA group consisting of a Product Manager, Product Designer, Decision Scientist, and Engineering Manager. In this position, you’ll Restructure core moderation flows based on product
requirements using a mix of live, snapshotted, and projected data Clean up legacy areas, restructure key flows, and prepare modular components for future microservice expansion Build and adapt unique experimentation systems to run advanced product and system tests Implement robust logging and monitoring to make high-volume flows observable, debuggable, and safe to change Balance strict technical
requirements (latency, memory, speed) with domain needs (explainability, extensibility) Work closely within our Web, QA, and EPDA setup while providing mentorship and support to help nearby engineers grow Own your services: Monitor and improve backend service performance and stability.
The team owns and monitors service-layer measurements (SLIs, SLOs, etc.) and participates in an on-call rotation, currently during working hours, though this may adapt to 24/7 in the future depending on operational needs.

You raise the quality bar without being a gatekeeper You document what you build - proposals, RFCs, and ADRs - so the next person doesn't have to reverse-engineer your thinking You are enthusiastic about AI technologies, use AI tools daily in your work, and proactively learn and experiment with how to adopt AI to boost engineering outcomes. You care about observability and monitoring - if something breaks on our queue ingestion or alerting pipelines, your team shouldn't be flying blind. You connect the dots between deep technical work and the critical safety and business impact it has on millions of Vinted users. You work well across teams and functions - whether that's pairing with Web or QA, discussing specialized moderation workflows with Operations, or aligning API contracts with other teams You use AI tools effectively for debugging, code optimization, and complex tasks — and you help others in
