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.

Business Units

• Vinted Marketplace: 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: 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

Vinted’s Marketing domain is growing - we’re on a mission to make Vinted known and loved as the go‑to destination for everything second‑hand. Marketing is one of the primary drivers behind our biggest strategic goals, from winning the USA market to expanding beyond fashion into a multi‑vertical platform.

We’re looking for 2 Data Scientists to join our Marketing Modelling Intelligence team to build, refine, and scale our core predictive and explanatory models. In this role, you will be the technical engine behind our Bayesian Media Mix Models (MMM), user value machine learning models, and advanced statistical frameworks. Your focus will be on engineering robust, high‑performing models that transform complex data into the precise insights our domain relies on.

Responsibilities

• Evolve Our Marketing Measurement: Code, calibrate, and scale our Bayesian Media Mix Models (MMM) and ROI frameworks to unlock precise business insights.
• Build and Deploy Core Models: Build and maintain sophisticated econometric and statistical models (MMM, GMV, engagement) to quantify marketing impact and guide multi‑channel growth.
• Automate Model Validation & Health Monitoring: Design automated frameworks and reliability metrics that continuously monitor model health and ensure long‑term accuracy.
• Build Next‑Gen, Automated Capabilities: Drive the ambition toward intelligent data products such as self‑healing MMMs using modern AI and automation to optimise model runtimes and scale our ecosystem as Vinted grows.
• Partner Decision Scientists & Marketing Leadership: Act as the core technical partner, translating complex mechanics into clear concepts and helping the team connect model outputs to robust business decisions.
• Champion Modelling Excellence: Maintain a high bar for code quality, rigorous validation, and reproducibility to ensure our data science practices remain clean and trusted.

About You

• Proven Data Science Experience: Hands‑on experience focused on advanced statistical, econometric, or time‑series modelling (experience in marketing measurement/MMM is an advantage).
• Deep Theoretical Knowledge: Strong foundation in advanced statistics, causal inference, and regression. Familiarity with probabilistic programming (e.g., PyMC) is a major plus.
• Research‑to‑Application Mindset: Ability to read scientific papers, explore state‑of‑the‑art techniques, and replicate or adapt advanced methodologies to solve complex problems.
• Production‑Grade Engineering: Highly proficient in Python, with a passion for building models as data products. You design your pipelines and code so they are modular, reproducible, and easily used or extended by other scientists.
• Business‑Minded Tech Partner: You care deeply about the why behind your code, naturally connecting technical model outputs to commercial metrics and business outcomes.
• Educational Background: A Master’s or PhD degree in a highly quantitative discipline (Statistics, Econometrics, Mathematics, Data Science, or similar).
• Impactful storyteller: A charismatic and confident presenter who navigates any topic’s technicality, actively driving and facilitating strategic business conversations across both technical and leadership audiences.
