You'll own product-critical features end-to-end — from technical design to rollout — in a large, modular Kotlin codebase where craft and velocity both matter. You'll work closely with Product, Design, Backend, and Frontend. Own features end-to-end: You'll take ownership from discovery and technical design through implementation, rollout, and iteration on features that help businesses pay, get paid, and stay in control.

You'll shape solutions with Product, Design, and Backend by clarifying tradeoffs across UX, performance, security, and time-to-market. You'll improve architecture, performance, and test strategy to scale the app without compromising stability. Grow the team's Android craft: You'll lead code reviews and technical discussions, share patterns, and mentor peers to raise the bar on quality and delivery.

Strong Android native experience:



You've shipped and maintained production features with Kotlin and are comfortable owning technical decisions end-to-end. Quality-driven mindset: You care about testing (unit, UI, snapshot), clean code, and pragmatic standards that keep teams moving fast. You use AI coding tools daily to amplify your output — not just experiment with them.

You're fluent in English and contribute through code reviews, knowledge sharing, and mentorship across technical and non-technical stakeholders. Fintech constraints — security, compliance, real-time data — push you to solve problems most mobile engineers never encounter. We value upfront technical design, team reviews, and smart slicing — quality drives the velocity our customers need.

Our org assigns one team lead per project across stacks, giving your team a clear mission and full autonomy on how it operates. Kotlin-first & modern concurrency : 100% Kotlin codebase with Coroutines + Flow throughout.

CI/CD & quality : GitHub Actions, Bitrise, Firebase Test Lab, Sonar, Fastlane.

Testing culture : 26k+ unit tests, 14k+ snapshot tests, 500+ UI tests. As an Android Engineer, you will join one of Qonto's squad teams , each organised around a clear project mission , with one team lead and full ownership of a product scope. You'll be part of a 140+ mobile engineering community within a 500+ Product Engineering department, working in focused teams of 5 to 10 people alongside Product, Design, and peers from Frontend and Backend.
