Meet Your Team: Demand Solutions

We are connecting the advertiser to the end users and on the one hand give users ads that are interesting to them and on the other hand find users for advertisers that would like their product. In order to do that we have built APIs that currently serve 2bn requests per day at low latency and on the other hand integrated ML models built by our data science team in order to serve the most interesting ads to our users.

A large part of the demand solutions system is a dashboard that is used by our internal and external users in order to make configuration changes to advertiser’s campaigns but that is mainly used as a tool for analysis. For this our dashboard features sophisticated analysis tools in order to help us and our partners to gain insights into their business and how to improve.

Join a team that is excited about the latest technologies and is highly interested in data, security, cloud computing, and mobile operating systems.

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.
