Senior Android Developer – SDK & Video/AdTech Focus

We’re looking for a Senior Android Developer to join our team and take a leading role in an ongoing project developing a high-performance Android SDK. This SDK powers video playback and monetization for major publishers and includes advanced integrations with ExoPlayer, Google’s IMA SDK (Ads), Prebid Mobile, and other advertising and analytics platforms.

This role is perfect for a developer who has deep experience building Android libraries, thrives in technically complex environments, and is comfortable working with media frameworks and real-time integrations. You’ll collaborate directly with our senior team and work in a fast-paced environment that values clean, testable code and pragmatic engineering decisions.

• Develop and maintain a production-grade Android SDK with a focus on media playback and advertising.
• Integrate and customize ExoPlayer, IMA SDK, and Prebid Mobile within the SDK.
• Build robust APIs and internal components for client app integration.
• Ensure the SDK is modular, efficient, and developer-friendly.
• Troubleshoot complex issues related to video rendering, ad loading, and event tracking.
• Work closely with client teams to support integration and resolve edge cases.
• Write clean, maintainable, and well-tested Kotlin code.
• Participate in design and architecture discussions, code reviews, and documentation.
  

• 5+ years of experience in Android development, with strong Kotlin proficiency.
• Proven experience building and maintaining Android SDKs or libraries.
• In-depth experience with ExoPlayer and media playback pipelines.
• Experience with ad tech integrations: IMA SDK, Prebid, VAST, VPAID, etc.
• Strong understanding of Android internals, threading, memory management, and performance tuning.
• Familiarity with event tracking, analytics SDKs, and custom player overlays.
• Comfortable debugging media playback issues and managing various device configurations.
• Experience working with CI/CD tools, Git, and modern Android build systems.
• Excellent communication skills and the ability to work independently.
  

• Experience with multi-tenant SDKs used across multiple apps.
• Familiarity with server-side ad stitching (SSAI) or client-side ad management strategies.
• Previous work with publishers or media companies.
• Knowledge of video encoding, DRM, and HLS/DASH streaming nuances.
• Experience with cross-platform media solutions (e.g., React Native or Flutter integrations).
