Android Developer II

Role & responsibilities

1. Own features end to end across OYO, CheckIn and My6: design, build, release, measure.

2. Build shared modules (search, booking, payments, personalisation) reused across the three

apps.

3. Ship server-driven UI so deals and campaigns go live without an app release.

4. Write and own backend-for-frontend APIs that shape data for mobile.

5. Keep the apps fast and stable on low-end devices and slow networks (crash-free, ANR and

latency targets).

6. Review code and mentor SDE-1s.

Area Must-have

1. Kotlin Coroutines (scopes, dispatchers, structured concurrency, cancellation),

Flow/StateFlow, sealed and data classes

2. Android UI Jetpack Compose (state hoisting, recomposition, side effects), View interop,

RecyclerView/DiffUtil, Navigation

3. Android architecture MVVM/MVI, Hilt/Dagger scopes, modularisation,

4. Room, DataStore, offline-first caching

5. Android platform Activity/Fragment lifecycle, process death and saved state, WorkManager

and background limits, deep links, Binder basics

6. Performance & stability Cold start, jank, memory leaks and heap limits, image

loading/caching, Crashlytics, ANR and crash trace debugging

7. Build & security Gradle, R8/ProGuard keep rules, app size, Play

8. Integrity, encrypted storage, staged Play rollouts

Good-to-haves

1. Multi-brand or white-label app architecture or Kotlin Multiplatform.

2. Payments (UPI, Google Pay, Apple Pay) and travel/booking domain experience.

3. Personalisation or recommendation features on mobile.

4. iOS (Swift) exposure.
