We're a cross-functional team of product management, UX, QA and engineering that owns its product area end to end.What you'll do\nBuild the features that keep buyers coming back, such as Watch Collection, Wishlist, and the user account.\nWork closely with product management and UX: challenge product ideas, propose simpler solutions, and bring your technical expertise together with their product expertise.\nDesign and build backend services and APIs with Java and Spring, implement the frontend changes a feature needs, and keep it all reliable in production.\nWhat you can expect\nA platform used by millions of watch enthusiasts worldwide, with the reach of an established marketplace and the short decision paths of a small team.\nOpen discussions about quality and trade-offs, where good arguments count for more than hierarchy.\nJava 25, Spring, MySQL; Vue.js, Jetpack Compose, and SwiftUI across web, Android, and iOS; GitLab CI; AI tools like Claude Code in our daily workflow.\n10% of your working time reserved for learning or personal projects.\nWhat sets you apart\nYou…Think in terms of the problem, not the ticket, and care whether a feature actually makes a difference for buyers.\nWrite code that others can read, change, and trust.\nAre most at home in the backend, but don't stop at the API when a feature needs frontend changes.\nUse AI tools like Claude Code every day and review their output as critically as you would a colleague's code. Experience in setting up and improving an agentic coding environment is a plus.\nEnjoy a good debate: you challenge ideas, including ours, and commit once a decision is made.\nValue pragmatism over purity and can tell \"good enough for now\" from \"this will hurt us later.\"\nYou bring hands-on experience with:Java and its ecosystem, including testing, CI/CD, and how software runs in production, and some of the tools we use (Spring, Maven or Gradle, SQL, GitLab).\nFrontend development on at least one of our platforms: web (Vue.js), Android (Jetpack Compose), or iOS (SwiftUI).
