Senior Go Backend Developer (User Experience 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, 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.
• Continuously search for ways to decrease the API response time for complex queries – we work with a few hundred terabytes of data.
• 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.
• Learn in a supportive environment that refines your potential and gives your career a solid foundation. 
• Be part of an international English-speaking team dedicated to scaling our adtech platform beyond our hundreds of millions of monthly active users.
