Meet Your Team: Demand Solutions

The Demand Solutions team builds the core technologies to help mobile publishers acquire the right users for their apps and games. The team is proud that adjoe’s software – developed 100 percent in-house – manages, provides, and analyzes advertisements for more than 200 million daily mobile users.

adjoe’s Demand Solutions team builds modern user interfaces and software and powers its analytics in the dashboard with state-of-the-art databases like Druid. All to give end users the insights they need. The team provides KPIs by APIs in milliseconds and supports adjoe’s partners by offering the highest availability without outages. This is thanks to working with proper code quality, different testing standards, different mechanisms to auto-scale, and redundant cloud infrastructure.

  • Be responsible for collecting the billions of daily API events and aggregating them in our Kafka and Kinesis streams with the goal of querying them from the data lake in a matter of seconds.
  • Design & maintain APIs used by our external partners for reporting and publishing configuration changes for advertisers like for example uploading new images and videos for ads.
  • Design & maintain APIs used by our mobile end users such that we can serve their traffic at scale.
  • Be part of an international English-speaking team dedicated to scaling our adtech platform beyond our hundreds of millions of monthly active users.
