Senior Go Backend Developer (Programmatic Supply Services Team) (f/m/d)

What You Will Do:

• Contribute to the development of our backend written +99% 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, SQS/SNS, etc., 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.
• Continuously search for ways to decrease the API response time for complex queries – we work with a few hundred terabytes of data.
• 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.
• 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.
