- Build and maintain UI components using Jetpack Compose, ensuring a consistent, performant, and accessible user experience.
- Implement asynchronous logic and reactive data flows using Kotlin Coroutines and Flows.
- Produce clean, well-tested code following established engineering best practices and the team's architectural guidelines.
- Review code and technical solutions proposed by other engineers and provide constructive feedback.
- Collaborate closely with engineers, product stakeholders and designers.
- Support production releases and contribute to maintaining a high level of app stability and user experience quality.
- Contribute to improving engineering practices, automated testing coverage, and technical documentation within the team.
- Mentor less experienced engineers and contribute to raising the overall technical level of the team.
