👥 Your role in the team

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

The Demand Solutions department develops the core technologies to assist mobile publishers in acquiring the right users for their apps and games. The team is proud that adjoe’s software – developed entirely in-house – manages, delivers, and analyzes advertisements for over 200 million daily mobile users.

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

Neben der Erfüllung hoher Standards bleibt Demand Solutions flexibel und unabhängig von den anderen Tech-Teams von adjoe. Um neue Plattformfunktionen schnell zu entwickeln, arbeitet dieses vielseitige Team am Go-Backend von adjoe, das Daten an das TypeScript React-Frontend liefert.

As part of the Demand Solutions team, the Core & Integrations team is responsible for the 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 such as our attribution partners – MMPs (Appsflyer, Adjust, etc.) – or aggregators working with the advertisers using our platform.

What You Will Do:

• Contribute to the development of our backend written in Go and maintain our microservice architecture used to communicate with our frontend (based on TypeScript React). To do this, you’ll use event buses like Kafka and SQS/SNS in order to have reliable asynchronous microservice communication.
• Work in a community of developers with whom you’ll share knowledge and contribute to peer code reviews.
• Work with modern databases such as Druid – but also with MySQL and Redis, where you’ll optimize queries and the way we query data to deliver few-millisecond response times.
• 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.
