• Build scalable, responsive, and user-friendly interfaces using Jetpack Compose.
• Implement scalable application architectures using MVVM, Clean Architecture, and modular design principles.
• Develop reusable and maintainable components across multi-module Android applications.
• Integrate RESTful APIs using technologies such as Retrofit or Ktor.
• Implement dependency injection using Hilt, Dagger, or Koin.
• Optimise application performance, reliability, responsiveness, and resource utilisation.
• Design and implement effective offline handling and resilient application behaviour.
• Manage Gradle configurations, build variants, dependencies, version catalogs, and multi-module builds.
• Own Android application releases, including build generation, versioning, Play Store publishing, and production deployment.
• Write comprehensive unit tests and contribute to automated testing and overall application quality.
• Participate in code reviews and maintain high standards of clean, secure, and maintainable code.
• Troubleshoot production issues, perform root-cause analysis, and implement sustainable fixes.
• Provide production and on-call support during critical releases and high-traffic events when required.
• Collaborate with Backend, QA, Product, DevOps, and other engineering teams to deliver features end-to-end.
• Contribute to technical design discussions, architecture decisions, R&D initiatives, and engineering improvements.
• Evaluate and contribute to the adoption of Kotlin Multiplatform (KMP) for shared business logic where appropriate.
• Work with Firebase and other supporting technologies to improve application functionality, monitoring, and reliability.
• Maintain technical documentation and contribute to engineering standards and best practices.

• Strong proficiency in Kotlin, Android SDK, and Jetpack Compose.
• Strong understanding of MVVM, Clean Architecture, modularisation, and scalable Android application design.
• Experience developing and maintaining multi-module Android applications.
• Hands-on experience with Hilt, Dagger, or Koin for dependency injection.
• Strong experience integrating REST APIs using Retrofit, Ktor, or similar frameworks.
• Good understanding of Android Gradle, build variants, dependency management, and version catalogs.
• Experience with Firebase and production application monitoring.
• Practical knowledge of Kotlin Multiplatform (KMP) is an advantage.
• Hands-on experience managing Google Play Store releases and production deployments.
• Strong understanding of Git, GitHub, Maven repositories, and artifact management.
• Experience building applications with a significant user base and supporting production environments.
• Strong knowledge of mobile application performance optimisation, offline capabilities, security, and reliability.
• Strong debugging, problem-solving, and root-cause analysis skills.
• Ability to write clean, testable, maintainable, and production-ready code.
