Senior Go Backend Developer (Advertising Dashboard 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 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 columnar databases such as Druid – but also with MySQL, 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
