[Hiring] Senior Android Engineer @Epic Kids Inc.

Role Description

You'll own Epic's native Android app, the main way kids open a book on Android phones, tablets and Chromebooks. It's a large, mature Kotlin codebase with some Java and xml UI layouts. You'll work independently and partner closely with our Android, iOS, backend and web engineers and with the US engineering team.

• Own and evolve the Android app across phones, tablets and Chromebooks.
• Own the reading experience: our in-house page renderer and page-flip animation, zoom and gestures, and Read-to-Me audio synced to word highlighting.
• Own offline reading (encrypted downloads, background work, local storage), Google Play Billing subscriptions, and the Play Store release pipeline.
• Drive performance, stability and quality: startup time, memory, ANRs and crashes, and test coverage.
• Modernize carefully: move legacy Java and RxJava code forward without breaking a live app; also move to compose UIs whenever possible.
• Over time, pick up some iOS/Swift work.

Qualifications

• 4 - 6 years of building and shipping native Android apps.
• Strong Kotlin, and comfortable working in mixed Kotlin and Java code.
• Deep experience with the Android View system, Fragments and custom Views: custom drawing, animation and touch handling.
• Reactive and async programming: RxJava 2 in production, plus Kotlin coroutines.
• Dependency injection, MVP or MVVM architecture and Networking with Retrofit and OkHttp.
• Local persistence with Room/SQLite, including schema migrations, and background work with WorkManager.
• Google Play Billing and the release pipeline: Gradle build variants, app signing, CI (Jenkins or similar), Play Console tracks and staged rollouts.
• Testing with JUnit, Mockito or MockK, Robolectric and Espresso.
• Bachelor's degree or equivalent practical experience.

Nice to have

• Media: ExoPlayer/Media3, MediaPlayer, and syncing audio to text.
• Handling encrypted media and content stored offline.
• Jetpack Compose, and the judgment to know when it fits alongside an existing View-based codebase.
• Performance tooling: Perfetto, Android Studio profilers, LeakCanary, New Relic or Crashlytics.
• Experience with kids' or education apps and children's privacy rules (COPPA).
• Interest in cross-platform mobile and some familiarity with iOS/Swift.

Compensation

40–50 LPA, with some flexibility for exceptional candidates.
