Android Developer

Design and develop secure, scalable, accessible, and high-performing native Android applications using Kotlin and Android development frameworks.

Build reusable user interfaces and navigation flows using Jetpack Compose and Android Views, aligned with Material Design and product design systems.

Apply appropriate architectural patterns such as MVVM, MVI, Clean Architecture, repository pattern, and unidirectional data flow.

Integrate RESTful APIs and backend services; manage authentication, authorization, caching, retries, timeouts, pagination, and error states.

Implement asynchronous processing and reactive state using Kotlin Coroutines, Flow, StateFlow, and lifecycle-aware components.

Use secure storage and Android security capabilities to protect credentials, tokens, customer data, and sensitive application state.

Develop unit, integration, and UI tests using JUnit, MockK/Mockito, Espresso, Compose testing, or equivalent tools.

Profile and optimize application startup, responsiveness, battery use, networking, memory, rendering, and application size.

Collaborate with UX/UI teams to convert Figma designs, prototypes, adaptive-layout requirements, and accessibility expectations into mobile experiences.

Participate in solution design, estimation, sprint planning, backlog refinement, code reviews, demonstrations, and retrospectives.

Support Gradle builds, build var iants, signing, CI/CD, internal testing, Google Play release readiness, and production monitoring.

Troubleshoot production issues, remediate defects, reduce technical debt, and improve mobile engineering standards.

5-10 years overall; 4+ years of recent mobile application development.

Strong hands-on Kotlin with knowledge of null safety, collections, lambdas, extension functions, generics, sealed classes, delegation, and Android platform APIs.

Ability to build adaptive interfaces, navigation, reusable composables/views, lists, forms, themes, animations, and accessibility support.

Experience with MVVM/MVI, Clean Architecture, repository pattern, dependency injection, modularization, and separation of concerns.

Practical experience with coroutines, suspend functions, Flow/StateFlow, structured concurrency, lifecycle awareness, and thread management.

Retrofit/OkHttp or equivalent, REST/JSON, serialization, API error handling, Room, DataStore, caching, pagination, and offline considerations.

Android Keystore, encrypted storage, secure token handling, certificate/pinning awareness, biometric authentication, and secure coding practices.

JUnit, MockK/Mockito, Espresso, Compose UI testing, mocking, testable design, code coverage, and regression support.

Android Studio, Gradle, Git, dependency management, profilers, CI/CD, signing, build variants, and Google Play workflows.
