Senior Android Engineer (w. Kotlin)

You will join our client’s mobile team as an embedded engineer building new features for their flagship Android news app. You’ll work inside Jira board, attend their standups, and ship code alongside their internal team. They handle back-end services; you own the native Kotlin layer. Android ships after iOS in a first-and-follow cadence, so you’ll benefit from design and product decisions already validated on the iOS side. What You’ll Build • A redesigned home screen with dynamic, personalizable content feeds. • Revamped navigation across the app. Audio integration for continuous/background play. • Vertical video playback. • Food and Sports brand destinations, including a Discover map (Google Maps SDK already integrated) and live scoreboards. • Embedded web views for games, puzzles, and interactive content from the CMS. • Architecture review of the existing ~19K-line Kotlin codebase during the design sprint. Requirements 5+ years of production Kotlin experience in consumer-facing Android apps. • Strong Android Views + ViewBinding/DataBinding skills (the codebase uses Views, no Jetpack Compose). Experience with MVVM architecture using ViewModel, Repository pattern, Hilt DI, and Navigation Component. • Experience with GraphQL clients, specifically Apollo Kotlin SDK. • REST API integration with Retrofit + Moshi. • WebView integration and JavaScript bridge patterns (addJavascriptInterface). • Gradle Kotlin DSL build configuration with product flavors. • Comfortable working inside an existing codebase with an established team. Nice to Have • Experience with media or publishing apps (news, streaming, content-heavy products) • Ad SDK integration (Google Ad Manager, Prebid, Amazon APS) • Firebase (Analytics, Remote Config, Cloud Messaging, Crashlytics) • Auth0 authentication flows on Android • Google Maps SDK and location services AndroidX DataStore (preferences + proto) • Permutive or similar audience/CDP SDK experience Originally posted on Himalayas
