Our methodology, the Qonto Way

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;
Our lean toolbox, Kaizen, PDCA, lets you monitor and drive continuous improvement collaboratively with your peers and manager;
Each engineer gets access to Cursor or Copilot, and we want people who use AI to raise the bar, not just to go faster.

Your future team

As an IOS Engineer, you will join one of Qonto's squad teams, each organized 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.

Our stack & practices

Our app is 100% Swift, built on MVP & Clean Architecture with 35+ independent modules. We use the Coordinator pattern for scalability, and all new screens are built in SwiftUI (MVVM) with async/await — 80+ screens already migrated. Project generation and build optimization run on Tuist. CI/CD covers Git Hub Actions, Bitrise, Firebase Test Lab, Sonar, and Fastlane.

We take technical excellence seriously: 30,000+ unit tests, 450+ snapshot tests, Swifty Mocky for mock generation, and LLMs integrated into our dev workflow. Our modular architecture (32 reusable modules + centralized design system) ensures fast builds, clear ownership, and safe iterations.
