AI at Qonto

AI is deeply embedded in how we work (here). Every Qontoer gets unlimited access to the best AI tools. We want people who experiment without waiting for permission, push AI beyond the obvious, know when to trust it, and when to question it.

Location:

Mission Join us as an Android Engineer

Help us build the mobile experience that 600,000+ European businesses rely on every day to manage their finances. 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.

Задачи:

• 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.
• Drive technical decisions in your squad: You'll shape solutions with Product, Design, and Backend by clarifying tradeoffs across UX, performance, security, and time-to-market.
• Raise app reliability and maintainability: You'll improve architecture, performance, and test strategy to scale the app without compromising stability.
• Tackle complex mobile challenges: You'll contribute to real-time synchronization, resilience patterns, and smooth navigation in a modular codebase with ~1,000 modules.
• 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.

Требования:

• 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.
• Problem-solving approach: You thrive in ambiguity and turn complex constraints into simple, robust solutions.
• AI-native workflow: You use AI coding tools daily to amplify your output — not just experiment with them.
• Collaborative by nature: You're fluent in English and contribute through code reviews, knowledge sharing, and mentorship across technical and non-technical stakeholders.

Условия:

• An AI-first engineering environment: Unlimited access to Claude Code, Cursor, and Copilot — and a culture that expects you to use them to raise the bar, not just go faster (click here to read our vision statement on AI).
• Engineering standards that scale: Strong code review culture, continuous refactoring, and a focus on correctness in a regulated context.
• A technically demanding domain: Fintech constraints — security, compliance, real-time data — push you to solve problems most mobile engineers never encounter.

Our stack & practices

Kotlin-first & modern concurrency: 100% Kotlin codebase with Coroutines + Flow throughout.

Architecture: MVVM + Clean Architecture with modular design (~1000 modules).

UI direction: New screens built with Jetpack Compose, with a large share of legacy views already migrated.

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

Testing culture: 26k+ unit tests, 14k+ snapshot tests, 500+ UI tests.

Your future team

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.

At Qonto, we understand that true diversity isn’t just about ticking boxes on a hiring checklist.
