Meet Your Team: Advertising Solutions

The Advertising Solutions team builds technologies that connect advertisers with ideal users for their apps and games. Integrated with adjoe’s ML models, our custom APIs serve 2B requests per day at low latency.

We’ve developed advertising campaign management and complex analytics tools that provide actionable insights on 200 million daily users to both internal teams and external partners. Our Go-based backend feeds data to a TypeScript React frontend, supporting sophisticated analysis tools built on columnar databases like Druid for sub-millisecond query response times, complemented by MySQL, Redis, DynamoDB, and Kafka.

For developers, this means working on high-performance systems that process massive datasets while maintaining an agile development approach – implementing advanced algorithms through deep learning approaches for campaign distribution and bid optimization, building intuitive dashboards, and creating APIs that power business decisions across the entire advertising ecosystem.

What you will do:

Contribute to the development of our demand solutions backend written all in Go and maintain our microservice architecture used to communicate with our dashboard (based on TypeScript React). To do this, you’ll use event buses like Kafka, SQS/SNS, and Kinesis 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 DynamoDB and ScyllaDB to deliver few-millisecond response times for our mobile APIs and Druid to support fast and insightful analysis in our dashboard.

Continuously improve our distribution in order to stay up-to-date with the latest changes on the Android and iOS platform.

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.
