Android Mobile App Developer

About the job

Boock is building a mobile app for readers on Android phones. We are looking for a hands-on Android Mobile App Developer who can architect, build, ship, and continuously improve a polished reading experience. This role is ideal for someone who has already built consumer mobile products using the modern Android stack and knows how to balance speed, product quality, performance, and maintainability.

You will help us create a fast, reliable, beautifully designed Android app for readers, with a phone-first experience and a codebase that is ready for tablets, foldables, and future Android form factors.

What you will do

Own the Android app from architecture to release, including development, testing, performance tuning, and Play Store delivery

Build high-quality product flows for reading, discovery, library, search, bookmarking, highlights, notifications, and account-related experiences

Develop the app using Kotlin and Jetpack Compose with clean, scalable Android architecture

Create responsive Android UI that works well on phones today and can extend cleanly to larger screens tomorrow

Implement offline-first content access, local persistence, caching, and smooth content loading

Integrate backend APIs, analytics, crash reporting, notifications, and release tooling

Set up or improve automated testing, CI/CD, QA workflows, and production monitoring

Collaborate closely with product, design, backend, and content teams to ship user-facing features quickly and well

Use GenAI tools responsibly to accelerate coding, refactoring, documentation, test generation, and prototyping

Contribute ideas for future AI-powered reader experiences such as smarter search, personalization, summaries, or in-app assistance

What we are looking for

Proven experience building and shipping Android apps in production

Strong hands-on expertise in Kotlin and Jetpack Compose

Strong understanding of modern Android architecture patterns such as MVVM, UDF, clean architecture, repositories, ViewModel, coroutines, and Flow

Experience with local persistence and offline-capable mobile apps using tools such as Room, DataStore, and Paging

Experience integrating REST or GraphQL APIs and building reliable sync or caching flows

Solid understanding of Android performance, including startup time, smooth scrolling, memory use, battery awareness, and network efficiency

Experience with testing across unit, UI, and instrumentation layers

Experience with CI/CD and release workflows using tools such as GitHub Actions, Gradle automation, Firebase App Distribution, Test Lab, or similar

Experience with analytics, crash monitoring, notifications, and feature rollout tooling

Strong product sense and attention to UI detail, usability, accessibility, and readability

Strong preference

Experience in reader, ebook, publishing, media, news, education, or content-consumption apps

Experience building features such as offline reading, annotations, highlights, search, recommendations, or personalized content feeds

Experience with Firebase services such as Crashlytics, Analytics, Remote Config, FCM, App Distribution, and Test Lab

Experience optimizing app performance with Baseline Profiles, benchmarking, or profiling tools

Experience with Google Play release management, subscriptions, or billing flows

Comfort using AI-assisted development tools such as Gemini in Android Studio or GitHub Copilot with strong engineering judgment

Nice to have

Exposure to SwiftUI, Kotlin Multiplatform, or other cross-platform/mobile ecosystem experience

Experience with GenAI integrations in apps using Firebase AI Logic, OpenAI APIs, or similar platforms

Experience with accessibility for reader experiences, including large text, TalkBack, dark mode, and long-session usability

Experience in early-stage product environments where speed, ownership, and pragmatic decision-making matter
