Senior Decision Scientist, Frontend Technologies

ppbBrief Info About Vinted /b 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. /p h3Information About The Position /h3 pYou will join the central data team within the Frontend Technologies domain. The Frontend Technologies domain is responsible for designing and helping implement architectural changes for each frontend platform: Android, iOS, and Web, resulting in clear boundaries, enablement of marketplace‑wide strategic initiatives, and a great member experience. /p pWe’re looking for a Decision Scientist to join the team to ensure the business impact of frontend architectural changes is estimated, trade‑offs are rigorously analyzed, and our long‑term platform strategy is grounded in evidence‑based insights. Despite working from a central data team within the domain, you are expected to partner with engineering managers, staff engineers and designers to co‑create, challenge default assumptions, and bring a proactive decision‑making lens to the table. /p pThis role is for someone who can independently own analyses from start to finish, contribute to strategic engineering decisions, and work closely with Engineering, Design, Analytics Engineering, and other Decision Scientists. You are a partner who can turn complex technical or business questions (e.g., modelling the financial and behavioural cost of an app crash, or mapping performance latency to conversion rates) into structured analysis, interpreting results, and communicating clear recommendations to stakeholders. /p h3In this position, you’ll /h3 ul liEnable Data‑Driven Platform Decisions: Drive the definition, implementation, and tracking of key technical and behavioural metrics that define frontend success. /li liBridge Technical Business Metrics: Turn highly technical questions (e.g., “What is the business cost of an app crash?” or “How does rendering speed impact member conversion?”) into structured insights. /li liProactive Co‑creation in Discovery: Partner with engineering and design leaders during the discovery phase to evaluate opportunity sizes, establish baseline metrics, and ensure no major architectural shifts are launched without clear decision criteria. /li liSupport Experimentation: Help design, monitor, and analyse A/B tests to evaluate the cumulative impact of platform optimisations and refactoring. /li liCollaborate within DSA: Engage with the broader Vinted Data Science Analytics community to share methodologies, standardise tooling, and scale our decision‑science standards. /li /ul h3About You /h3 ul liExperienced Decision Partner: Working experience in decision science, product analytics, or business intelligence (ideally within a tech‑product or platform‑engineering environment). /li liTechnically Proficient: Highly proficient in SQL and Python (or R) for writing clean, efficient queries to handle large, complex datasets. Experience with version control (Git) and dbt is a plus. /li liAnalytical Statistical Mindset: Deep understanding of statistical methods, A/B testing methodologies, and analytical framing. You know how to structure an analysis to inform a decision, not just present data. /li liStrong Communicator Storyteller: Able to translate complex technical architectures and statistical findings into clear, persuasive, and visual recommendations for both technical and non‑technical audiences. /li liPragmatic and Proactive: Possess a strong intuition for return‑on‑investment on analytical tasks, knowing when to choose short‑term pragmatism over theoretical perfection. /li liComfortable with Technical Domains: You do not need to write frontend application code, but you have the curiosity and capability to understand platform‑level architectures (caching, latency, app‑store release cycles). /li /ul h3Work perks /h3 ul liThe opportunity to benefit from our share options programme /li li25 days of paid annual leave /li liNewest MacBook models /li liConfidential Employee Assistance Program (EAP) for you and your family /li liFrequent team‑building events /li liHome office support: we provide IT workstation equipment and a personal budget of up to €540 for home workplace furniture /li liLunch benefit per working day /li liAccess to a discounted gym membership plan /li liA personal monthly budget for shopping on Vinted /li liCollective Defined Contribution Pension plan /li liNS Business Card for your commute to the office by public transport /li liThe opportunity to spend up to 90 days per year – 21 of which can be spent working outside of the EU – on workation /li liA dog‑friendly office /li /ul h3Working at Vinted /h3 pWe invest in your professional growth!
