Product Owner

Overview
adjoe builds the technologies behind mobile apps growth and monetization. With our core product Playtime, we've become the global leader in rewarded advertising, an ad unit built on a simple premise: users earn real in-app rewards for engaging with new apps. The result is one of the most effective value exchanges in adtech, connecting advertisers and publishers with over 770 million users annually.

Creating solutions that run on 13% of the world’s smartphones

The Mobile Integrations team builds the core technology that turns advertising from an interruption into a rewarded experience for 770 million users. We own the robust, lightweight, integration layer between our ad engine and the global mobile ecosystem, ensuring our technology operates with minimal overhead while reaching a massive portion of the smartphone market.

On the client side, our technology performs smoothly across 20 million daily SDK initializations. We build native Swift and Kotlin SDKs optimized for ms initialization and minimal binary overhead, with Unity, Flutter, and React Native wrappers that provide a unified API across the entire mobile ecosystem. Behind the scenes, a high-throughput Go and DynamoDB architecture handles the real-time state synchronization of millions of concurrent sessions. When your code runs on nearly one out of every seven smartphones on Earth, every millisecond of execution and every byte of memory counts.

What you Will Do:

• Own and prioritize the Mobile SDK product backlog, balancing customer needs, business priorities, technical requirements, and engineering capacity.

• Translate product and developer needs into clear requirements, user stories, acceptance criteria, and actionable priorities for the engineering team.

• Drive feature delivery from discovery and planning through development, testing, release, and post-launch evaluation.

• Work closely with Android, iOS, Backend, QA, and other stakeholders to manage dependencies, resolve blockers, and ensure smooth delivery.

• Gather and analyze feedback from customers, developers, and internal teams to identify integration pain points and opportunities to improve the SDK and developer experience.
