  • Kraków
  • Kraków

Passionate about Big Data? Wanna have an impact on the shape of the mission-critical systems while working with the newest technology?
Join our Reporting team and become a Scala developer!


As part of the Ad Engineering unit, the Reporting team is one of the teams responsible for development of the in-house advertising system, used by the internal sales organisation across Schibsted and offering direct booking of advertising campaigns to external customers. Our business critical systems are accounting for around 150 million Euros in advertising revenue for the Schibsted group.

Our Reporting team is responsible for Big Data processing. We are converting gigabytes of data, in the form of events to provide reports about campaign’s performance. Currently we are investing and developing extensively our Data unit, and expect a lot of R&D projects to be launched in the near future. Our current stack is based on microservice architecture written in Scala.

The team currently consists of 4 backend developers, based in Cracow, and we are looking for two more to join it. The development team is fully responsible for the product from the technical point of view, being able to decide on the architectural choices, libraries used and solutions built. We work in Scrum. We collaborate closely with other teams within our business unit, especially from the Data area with the ad-serving solution of choice - Xandr.


We are looking for an experienced backend developer, with a solid history of working with JVM languages and a strong motivation to learn Scala , as our current stack is written in it.

As part of the Reporting team, you will be responsible for developing and maintaining Reporting API and working on various R&D projects together with the advertising data science and advanced analytics team. You will be working closely with other engineering teams both from within Schibsted and external, responsible for delivering 3rd party tools we use (p.ex. Xandr ad serving).

In your daily work, you will be mainly focused on coding - delivering on the new requested functionalities or services, but also spend quite some time on innovation - looking into new business opportunities, researching and building POC.

To become fully operational within your role and staying up to date, you will also have to check third-party documentation, support users, debug, maintain and operate the system as well as acquire knowledge from the ad-tech domain.

Once you learn the system, together with the rest of the team, you will continuously work on its technical evolution, scaling and simplification. We hope you will be able to take an active part in deciding how to implement new features and what architectural decisions to make.
