Meet Your Team: Core & Integrations Team (part of the Demand Solutions team)

The Demand Solutions department 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 department builds modern user interfaces and software and powers its analytics in the dashboard with state-of-the-art databases like Druid. All to give advertisers and account managers the insights they need. The team provides statistical data via a dashboard in order to supply our partners with valuable insights. For this we leverage machine learning models built by our BI analysts and data scientists.

Besides delivering high standards, Demand Solutions remains flexible and autonomous from adjoe’s other tech teams. To develop new platform features fast, this versatile team works on adjoe’s Go backend, which feeds data to the TypeScript React frontend.

As part of the Demand Solutions team, the Core & Integrations team is responsible for core logic of our advertising platform: campaign distribution to find the best combination of advertising campaigns for end users, campaign management API to optimize existing advertising campaigns and some other smaller API products.

The Core & Integrations team also handles integrations with our external partners like our attribution partners – MMPs (Appsflyer, Adjust, etc.) or aggregators working with the advertisers using our platform.



What You Will Do:

  • Support partners by providing them with raw or aggregated data based on their business needs – we believe in data transparency and well-documented open APIs.
  • Collaborate with our Data Science team to solve complex math problems used to optimize our ML algorithms that are dedicated to delivering the right ads to the right users and integrate their solutions into adjoe’s application.
  • 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.
  • Be part of an international English-speaking team dedicated to scaling our adtech platform beyond our hundreds of millions of monthly active users.

  • You have worked in software development for 5+ years.
  • You have gained profound experience with building web applications in Go for at least 3 years.
  • You also know how work effectively with key-value databases (Redis, DynamoDB) and to optimize their use for high-volume traffic
