Senior Mobile Developer (SDK | AdTech | Android & iOS)

JedyApps is a fast-growing mobile technology company that develops, acquires, and scales Android and iOS applications reaching millions of users worldwide.

Our core product is a monetization and analytics SDK that powers ad delivery, engagement, and data collection across both our own apps and external partner apps.

We’re looking for a Senior Mobile Developer to take full ownership of this SDK — leading its architecture, implementation, and evolution across both Android and iOS platforms.

You’ll be responsible for the SDK’s architecture and hands-on development on Android and iOS, ensuring it’s lightweight, stable, and easy to integrate by external developers.

This is a highly technical and impactful role involving close collaboration with our backend, analytics, and monetization teams.

Integrate and optimize ad networks and mediation partners (AdMob, AppLovin, GAM, etc.) for both Android and iOS.
Develop SDK modules for analytics, A/B testing, and engagement tracking.
Ensure SDK performance, stability, and backward compatibility across platforms.
Collaborate with backend, data, and partner teams on integration and event tracking.
Set up coding standards, CI/CD pipelines, and automated testing for SDK releases.
Provide support and technical guidance to client developers during SDK integration on both Android and iOS.

Requirements:

4+ years of experience in mobile development, including both Android (Kotlin/Java) and iOS (Swift/Objective-C).
2+ years of hands-on experience with SDKs, libraries, or ad-tech systems.
Proven experience building or maintaining SDKs/libraries used by external clients.
Deep understanding of ad mediation, bidding systems, and monetization SDKs.
Experience designing lightweight, modular SDK architectures and optimizing performance across platforms.
Familiarity with Firebase, GA4, Remote Config, or similar analytics tools.
Excellent debugging, communication, and documentation skills.
