Beschreibung

adjoe is a leading mobile ad platform developing cutting-edge advertising and monetization solutions that take its app partners' business to the next level.

Meet Your Team:
Programmatic Supply

Did you know that in-app ads are sold in a real-time auction before they get rendered by adjoe's Android and iOS SDK in thousands of mobile apps?

It's exactly for this that adjoe has built its own platform. Our backend system can simultaneously handle a few billion auctions in real-time every day.

It receives price bids for every ad impression via API from more than 20 different companies buying potential ad inventory.

Behind the auction scenes, we have an impressive prediction model working to figure out if an ad will lead to an app install or not.

The algorithm requires operating data from different data sources and performs calculations in real-time.

We've built the core of our algorithm around Apache Flink with 10+ jobs and Kafka to be able to handle these events.

Join our discussions, explore implementation, and put your problem-solving skills to the test in our cross-functional Programmatic team
