You are the creator of smooth and intuitive mobile experiences! Within our Mobile expertise hub in our vibrant Brussels agency, your mission is to design and develop innovative, high-performance, and user-centric iOS applications. On a daily basis, you will:
Design and develop robust native applications for the Apple ecosystem (iPhone, iPad) using primarily Swift (and potentially Objective-C for maintenance).
Collaborate closely with UI/UX designers, Product Owners, and backend developers to seamlessly integrate RESTful APIs and deliver the best possible user experience.
Guarantee code quality and stability by writing automated tests (unit and UI) and actively participating in peer Code Reviews.
Optimize application performance, identify bottlenecks, and resolve bugs to ensure perfect fluidity with every user interaction.
Deploy and maintain applications on the App Store, mastering the publication processes and continuous integration tools (CI/CD, Fastlane).
Ensure a continuous technological watch on the latest iOS ecosystem updates (SwiftUI, Combine, new Apple frameworks) to proactively propose modern solutions to our clients.
Holding a degree in IT, software engineering, or computer science, you have at least 3 years of successful hands-on experience in native iOS mobile development.
You perfectly master Swift and possess a solid understanding of fundamental iOS frameworks (Foundation, UIKit, and ideally SwiftUI).
You are highly comfortable with modern mobile software architectures (MVVM, VIPER, Clean Architecture) and version control tools like Git.
You have a strong sensitivity for UI/UX design and ergonomics, with a drive to build "pixel-perfect" interfaces that strictly respect Apple's Human Interface Guidelines
Endowed with an excellent team spirit, you are curious, rigorous, and love sharing your technical discoveries with your peers.
Knowledge of Agile/Scrum methodologies, a passion for innovation, and fluency in English (French or Dutch is a major asset in Brussels) make you the ideal candidate for our international context.
