We're looking for a Senior Software Engineer with strong Flutter/Dart experience to join a team building large-scale mobile platform capabilities used by millions of users globally.
This is not a standard app development role. The focus is on scalable platform engineering, SDK integrations, performance, reliability, and building clean cross-platform architectures that operate at very high scale.
You'll be working across Flutter, native mobile layers, SDK integrations, and platform tooling in a modern engineering environment with a strong emphasis on quality and long-term maintainability.
Key experience:
- Strong commercial experience with Flutter/Dart
- Experience integrating native mobile functionality across iOS and/or Android
- Exposure to SDK development or SDK integrations
- Understanding of scalable mobile architectures and performance optimisation
- Experience with build/release tooling such as Gradle, Xcode, CI/CD pipelines etc.
- Any exposure to C++, native runtimes, or lower-level platform engineering is highly beneficial
Nice to have:
- Experience within high-scale consumer product environments
- Cross-platform/mobile platform engineering background
- Experience working in complex multi-language systems
This is a great opportunity for someone who enjoys solving engineering problems beyond just UI development and wants to work on highly scaled mobile platform challenges.
