The role:

At FDJ United, collaboration, craftsmanship, and continuous learning are central to how we build products. As part of our growing iOS team, you'll contribute to high-impact features used across multiple brands while working in a supportive environment that values ownership, innovation, and teamwork.

Our engineers take responsibility across the entire lifecycle — from architecture and implementation to testing, monitoring, and ongoing improvements.

We're now looking for an experienced iOS Developer who has a strong command of Swift, SwiftUI, async/await, and modern testing practices to help us craft robust, scalable, beautifully engineered mobile experiences.

As part of a regulated group committed to safe and sustainable entertainment, every engineer also plays a role in ensuring responsible development and operational excellence.

What You'll Do

Design & Implementation

• Develop high-quality, performant iOS applications using Swift, SwiftUI, Combine, async/await, and other modern frameworks.
• Contribute to the evolution of our architecture, helping shape modular, maintainable codebases supporting multiple brands.
• Participate in technical design discussions, proposing solutions to complex engineering challenges.

Testing & Quality

• Build reliable, maintainable Unit Tests, UI tests, and integration tests using frameworks like SwiftTesting, XCTest and XCUITest.
• Ensure code quality through peer reviews, automated checks, and continuous refactoring.
• Work closely with QA automation engineers to evolve shared tooling, frameworks, and CI/CD quality gates.

Collaboration & Delivery

• Work in a cross-functional Agile team alongside Product Owners, QA Engineers, Backend Developers, and Designers.
• Participate in sprint planning, refinement, and release preparation.
• Contribute to a strong engineering culture of shared learning, constructive feedback, and continuous improvement.

Operations & CI/CD

• Support the full lifecycle: monitoring, debugging, handling incidents, and continuously tuning performance.
• Contribute to CI/CD pipelines for automated testing, builds, and deployment workflows.

Skills & Experience We're Looking For

• Strong experience developing iOS applications with Swift, including advanced language features.
• Solid hands-on experience with SwiftUI, async/await, Combine, and modern concurrency patterns.
• Deep understanding of iOS architectural patterns (MVC, MVVM, Clean, etc.).
• Proficiency writing and maintaining Unit Tests and UI Tests using SwiftTesting, XCTest and XCUITest.
• Familiarity with automated build and release processes (CI/CD), ideally with Jenkins, Fastlane, or similar tools.
• Ability to write clean, testable, maintainable code and drive quality practices across the team.

Professional Skills

• Strong communication skills and the ability to collaborate in a cross-functional setting.
• Comfortable participating in design sessions, code reviews, and architecture discussions.
• Experience working with Agile methodologies.
• Mindset of ownership: you want to build it, measure it, improve it, and support it.

Nice-to-Have Experience

• Experience with modular architectures, multi-brand shared codebases, or feature modules.
• Familiarity with tools like SwiftLint and SwiftFormat.
• Experience integrating with backend services using REST or WebSockets.

Who You Are

• A curious engineer who loves learning and exploring new iOS frameworks & tools.
• Someone who cares deeply about code quality, maintainability, and thoughtful design.
• A strong collaborator and communicator who values teamwork as much as technical excellence.
• Driven, autonomous, and eager to influence the product and technical direction.
• Comfortable balancing innovation with regulatory, compliance, and operational constraints.
