Data Engineer

BA Markets wants to professionalise and streamline its activities with regards to data streaming. Therefore, a new agile team has been created to build up a technical platform for BA Markets users to get a hub for all required streaming services. ​

The team will develop the service suite largely internally but will also rely on managed vendor services, such as Databricks. The streaming technology used is Kafka. ​

Many BA Markets users are technically quite advanced so the central data streaming team must constantly keep up to date to deliver state of the art services. Because of that, there will be constant development opportunities for the candidate, and the candidate must be comfortable to work in a fast-changing, international environment. The team consists of four members in Hamburg, one member in Stockholm and should also have three colleagues in Poland.
