⭐ Mission

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

As a Senior iOS Engineer, you will own product-critical areas of our 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 iOS 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, 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 increase team velocity and quality.

🏅 What we're looking for

Strong iOS experience: You've shipped and maintained production features with Swift, and you're comfortable owning technical decisions end-to-end.
Quality-driven mindset: You care about testing (XCTest, snapshot testing), 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

Swift-first & modern concurrency: 100% Swift codebase with async/await patterns throughout.
Architecture: MVP + Coordinators with 30+ reusable modules; new screens in SwiftUI (MVVM), with 80+ already migrated.
Tooling: Tuist with caching for fast builds.
CI/CD & quality: GitHub Actions, Bitrise, Firebase Test Lab, Sonar, Fastlane.
Testing culture: 30,000+ unit tests and 450+ snapshot tests.
