⭐ Mission

Build reliable, fast, and secure mobile experiences that help European businesses run their finances with confidence.

You'll own product-critical areas of our Android app and partner closely with Product, Design, Backend, and Frontend to turn complex constraints — scale, performance, and a regulated environment — into simple, powerful customer experiences.

You'll ship, iterate, and improve what you build, and raise the bar for quality through strong engineering practices and technical leadership.

🤖 As a Senior Android Engineer at Qonto, you will

• Own features end-to-end: From discovery and technical design to implementation, rollout, and iteration, deliver experiences that help customers pay, get paid, and stay in control of their finances.
• Drive technical decisions in your squad: Shape solutions with Product, Design, and Backend by clarifying tradeoffs (UX, performance, security, and time-to-market), not just implementing tickets.
• Raise app reliability and maintainability: Improve architecture, performance, and test strategy so we can scale without compromising stability.
• Solve complex mobile challenges: Contribute to real-time synchronization, resilience patterns, and smooth navigation flows in a large, modular codebase.
• Contribute to the team’s growth: Lead by example in code reviews and technical discussions, share patterns, and mentor peers to raise the bar on Android craft and delivery.

🏅 What we're looking for

• Strong Android native experience: You've shipped and maintained production features with Kotlin, and you're 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, work effectively across technical and non-technical stakeholders, and contribute to the team through code reviews, knowledge sharing, and mentorship.

🔧 What you'll get

• An AI-first environment with unlimited access to the best AI tools on the market: Claude Code, Cursor, Copilot, Notion AI. (Click HERE to read our vision statement on AI at Qonto.)
• A strong engineering community: 400+ Product Engineers and a 140+ mobile team, working in small, autonomous cross-functional squads.
• Engineering standards that scale: Strong code review culture, continuous refactoring, and a focus on correctness in a regulated context.
• A technically ambitious 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.

💬 Hiring Process

Our process usually takes 2–3 weeks and includes 4 steps:

1. First call with a Talent Acquisition Manager
2. Manager interview with your potential future manager
3. Technical case + debrief with two Android engineers
4. Final interview with your manager's manager

If you've read this far and thought "that sounds like me but I don't check every box" — apply anyway. We hire on potential and mindset, not checklists.
