About the role
We are seeking a motivated Android Developer with a backend mindset to design, build, and maintain Jetpack Compose-driven applications backed by Node.js services. The ideal candidate is comfortable owning features end-to-end — from crafting declarative interfaces to building and consuming the APIs that power them. You'll work closely with designers, product managers, and senior engineers to deliver polished, full-stack mobile experiences.
Key Responsibilities
Jetpack Compose Development & Feature Delivery
- Build and maintain Android applications using Jetpack Compose as the primary UI framework.
- Create reusable, composable UI components following MVVM architecture.
- Leverage Kotlin Coroutines and Flow for reactive data flows and concurrency.
- Implement navigation, state management, animations, and gesture handling using Compose idioms.
- Translate Figma designs into pixel-accurate, responsive Compose layouts across device sizes and form factors.
Node.js Backend Development
- Develop and maintain RESTful APIs using Node.js with Express or Fastify.
- Design database schemas and perform CRUD operations with PostgreSQL or MySQL.
- Implement authentication flows, middleware, and input validation on the server side.
- Write clean, documented API endpoints that the Android layer consumes directly.
- Support deployment and environment management using Docker, PM2, or cloud platforms.
Integration & Code Quality
- Connect Compose UI to backend services using Retrofit, OkHttp, or Ktor Client.
- Handle JSON serialization and deserialization with Kotlin Serialization or Gson.
- Participate in code reviews, giving and receiving constructive feedback across both codebases.
- Use Git for version control and follow consistent branching strategies.
Performance, Debugging & Monitoring
- Profile and optimize Compose rendering performance using Android Studio Profiler.
- Monitor and triage crashes using Firebase Crashlytics.
- Log, monitor, and debug Node.js services using tools like Morgan or Datadog.
- Ensure smooth performance across supported Android versions and device types.
Continuous Learning & Growth
- Stay current with Jetpack library updates, new Android APIs, and Google I/O announcements.
- Follow Node.js ecosystem developments including framework updates and security patches.
- Share knowledge with the team through demos, documentation, or internal tech talks.
- Explore emerging patterns such as Glance for widgets, Material 3, and server-driven UI.
Qualifications
Qualifications
- Bachelor's degree in Computer Science, Information Technology, or a related field (or equivalent practical experience).
- 1–3 years of Android development experience with at least one Jetpack Compose-based app shipped to the Google Play Store.
- Proficiency in Kotlin and Jetpack Compose; understanding of the declarative UI paradigm.
- Working knowledge of Node.js and experience building or maintaining REST APIs.
- Familiarity with PostgreSQL or MySQL.
- Understanding of MVVM architecture and clean separation of concerns.
- Experience consuming and designing RESTful APIs with JSON.
- Comfortable using Android Studio, terminal-based workflows, and Git.
- Strong problem-solving skills and a willingness to learn across the stack.
Preferred Skills
- Experience with Kotlin Coroutines, Flow, and State
Flow for reactive programming.
- Familiarity with TypeScript on the backend.
- Exposure to Next.js for server-side rendering, API routes, or full-stack web companion apps.
- Experience with ORMs such as Prisma, Drizzle, or Type
ORM for type-safe database access.
- Familiarity with tRPC for end-to-end type-safe API layers.
- Exposure to CI/CD pipelines using Fastlane, GitHub Actions, or Firebase App Distribution.
- Experience with Docker for local development and deployment.
- Knowledge of Firebase services (Auth, Firestore, Cloud Messaging).
- Familiarity with Room for local persistence and data caching strategies.
- Familiarity with WebSockets or real-time data patterns.
- Understanding of accessibility best practices and localization in Compose.
- Any exposure to GraphQL or serverless functions is a plus.
