Meet Your Team: Programmatic Solutions
The Programmatic Solutions team powers adjoe’s real-time ad network solution integrated with leading mobile mediation platforms on both Android and iOS.
Our focus lies in building adjoe’s own Ad Network – a smart bidder leveraging machine learning to optimize campaign performance by predicting conversion probability and lifetime value in real time.
The team is responsible for both the adjoe Ads platform that decides which ad to display and our Android/iOS SDKs that render these ads and provide tracking events to the backend.
We’ve also developed tools for app publishers to manage their integrations, analyze monetization performance, and assess ad user experience through dashboards and APIs.
For potential teammates, working in the Programmatic Solutions team means applying your problem-solving skills in adjoe’s advanced programmatic ecosystem — where milliseconds directly impact both revenue and relevance.
