contribute to technical decisions, review your teammates' code, and occasionally mentor others. The team culture is flat, collaborative, and genuinely fun to work in.

You will be joining a cross-functional team working on a live mobile application that is already on the market and is now being migrated from Unity to Flutter. This is a technically interesting moment to join 2014 the project has a long runway, and if the migration goes well, the same approach will be rolled out across a wider application portfolio as part of a major long-term platform transformation.

• Show up to stand-ups, planning sessions, and retrospectives with ideas, not just updates

Requirements:

• 5+ years of professional software engineering experience, with at least 2 years of hands-on Flutter and Dart production experience
• Strong grasp of Flutter app architecture, widget lifecycle, and state management (BLoC preferred, Riverpod also welcome)

• Comfortable working with Firebase services such as Firestore, Authentication, Cloud Functions, or Push Notifications
• Familiarity with offline/online sync strategies and data caching on mobile
• Experience working in and modernising existing codebases, not just greenfield projects
• Good understanding of CI/CD pipelines and release processes for mobile

Desirable:

• Experience with Unity or other cross-platform frameworks
• Background in games or children's digital products
