• Develop and maintain shared components, including navigation, state management, networking, and payment workflows.
• Work on financial and payment features with a strong focus on reliability, error handling, and transaction security.
• Investigate and resolve performance issues, memory leaks, ANRs, and crashes.
• Write unit and integration tests and improve the testability of existing components.
• Participate in code reviews and help maintain high engineering standards.
• Collaborate with Backend, Product, and QA teams to deliver reliable features.
• Identify technical debt and propose practical, incremental improvements.
• Contribute to technical discussions, knowledge sharing, and mentoring other engineers.
Requirements
• 5+ years of professional Android development experience.
• Strong proficiency in Kotlin and a solid understanding of Android SDK and application lifecycle.
• Hands-on experience with Jetpack Compose.
• Strong understanding of software design principles, SOLID, and Clean Architecture.
• Practical experience with MVVM and MVI architecture patterns.
• Strong knowledge of Kotlin Coroutines, Flow, and StateFlow.
• Experience with dependency injection frameworks, preferably Hilt.
• Experience with Retrofit, OkHttp, and RESTful APIs.
• Good understanding of Android Navigation, deep linking, and back-stack management.
• Experience working with multi-module Android projects and Gradle.
• Experience writing unit tests using JUnit, MockK, Mockito, or similar tools.
• Ability to investigate complex technical issues and troubleshoot production problems.
• Experience with Git, code reviews, and collaborative development workflows.
Nice to Have
• Experience building fintech, banking, or payment applications.
• Knowledge of Android application security, secure storage, and encryption.
• Experience with Gradle Convention Plugins and build performance optimization.
• Familiarity with CI/CD pipelines, particularly GitLab CI.
• Experience with Sentry, Firebase Crashlytics, or similar monitoring tools.
• Familiarity with DataStore, WorkManager, FCM, and Android Widgets.
• Experience working on large-scale applications with a significant user base.
• Previous experience mentoring engineers and contributing to architectural decisions.
What We Value
We value engineers who take ownership of their work, care about product quality and reliability, and approach complex problems with a practical mindset.
You should be comfortable working with an existing codebase, making thoughtful technical decisions, and collaborating with others to build solutions that are maintainable, scalable, and reliable.
