• Maintain WebRTC audio and video calls, real-time chats, encrypted data storage, and the Wear OS companion application;
• Support Media3/ExoPlayer and Spotify integrations;
• Manage releases through Google Play, Firebase App Distribution, and alternative distribution channels;
• Support different product flavors, regional builds, and white-label configurations;
• Update dependencies, improve legacy code, reduce technical debt, and introduce unit tests;
• Participate in code reviews and collaborate with development and QA teams.

Required experience and skills

• 5+ years of commercial native Android development experience;
• Strong Senior-level ownership and the ability to work independently with a large production codebase;
• Expert knowledge of Kotlin;
• Ability to read, understand, and modify production Java code;
• Strong hands-on commercial experience with RxJava, preferably RxJava 3, including RxAndroid;
• Strong practical knowledge of the classic Android View system: XML layouts, ViewBinding, and custom views;
• Practical commercial Android BLE experience;
• Experience with GATT services and characteristics, including read/write/notify operations;
• Experience with BLE connection management, reconnect logic, background restrictions, foreground services, and connection stability;
• Experience with Hilt or Dagger 2;
• Experience with Room and Android Navigation Component;
• Experience maintaining large multi-module Gradle projects;
• Understanding of build variants, product flavors, and complex build configurations;
• Experience with the Google Play release lifecycle;
• Experience maintaining and debugging production applications;
• Ability to investigate issues and make technical decisions without constant supervision;
• English level B2 or higher.

As a plus

• RxAndroidBle or similar BLE libraries;
• OTA/DFU experience, including Realtek/RealSil or similar solutions;
• WebRTC, audio/video calls, and audio-routing experience;
• Wear OS and Jetpack Compose experience;
• End-to-end encryption, Olm/Matrix, or SQLCipher;
• Media3, ExoPlayer, or MediaSession;
• GitLab CI and fastlane;
• Firebase App Distribution;
• Experience distributing Android applications outside Google Play;
• Experience supporting applications for the Chinese market.

Technology stack

What we offer

• Fully remote, full-time cooperation;
• A long-term product with an established user base;
• Work with technically complex mobile functionality and physical Bluetooth devices;
• A professional development plan and regular feedback;
• Compensation for approved courses and certifications;
• 20 paid working days per year for vacation and sick leave;
• Salary reviews based on performance and professional growth.
