Within 1 month, you have a good understanding of the current architecture of the website and successfully built and shipped native features or enhancements within our mobile apps.
Within 3 months, you have proactively identified and implemented a tangible improvement to mobile build pipelines, automated testing and development workflow, demonstrably saving time or reducing friction for the mobile development process.
Within 6 months, you take ownership over significant mobile app features or modules (especially iOS-centric ones), managing them from scoping through development, testing, and release.
Within 9 months, you propose architectural improvements to our mobile app codebase or the web-native integration layer, enhancing maintainability, performance, and future feature development.
On a typical day you might:
Implement and refine both native and web UI elements and interactions based on designs for our iOS and Android apps.
Develop and integrate native functionalities (e.g., push notifications, platform-specific APIs) that enhance the core PWA experience.
Work on the bridge and communication layer between the web view and the native app shell.
Propose and discuss mobile-specific user experiences and native integrations together with the designer, and product manager.
Identify performance bottlenecks or areas for improvement in the mobile apps and refactor code or implement native solutions.
Break down mobile-focused features or epics into specific tasks and discuss implementation strategies, especially for iOS, with the tech lead and team.
What we offer:
Top-notch engineers as colleagues. We like to hire experts.
A modern mobile development environment leveraging web technologies combined with native development (Swift for iOS, Kotlin for Android). Experience with bridging technologies is a plus.
Your work directly impacts millions of users across the globe playing hundreds of millions of game sessions per month.
A lot of responsibility and freedom. We hire only experts and trust them to deliver excellent results.
Flexible working hours and location. The results are what count!
Team weeks: we organize a week somewhere in Europe once or twice per year. We pay for transport and accommodation so you can have fun with the team.
The opportunity to play games and claim it's work.
Reach out if:
You have demonstrable experience developing native mobile applications, with a strong focus and deep understanding of iOS development (Swift/Objective-C and core iOS frameworks). Experience with Android (Kotlin/Java) is a significant plus.
You have experience with or are eager to learn more about React web development.
You have experience working with or integrating web views (WKWebView/WebView) or PWAs within native mobile applications.
You have experience optimizing mobile applications for responsiveness, and smooth user experience across various iOS devices and versions.
You can think from the perspective of the mobile user and understand platform conventions.
You have experience interpreting mobile analytics to drive development choices.
You are intelligent, efficient, and organized. You have an attention to detail.
You like open, efficient, and to-the-point communication and you have experience working effectively in a remote team.
