Principal Engineer Interactive Systems

During the current situation we are fully remote, in the future there is the possibility of working in an office in Wrocław, Warsaw or Bydgoszcz.

At Pragmatic Brains, we are creating a breakthrough system to support human interactions in the digital world

Our headline is “Real Life Interactions in the Digital World” and that’s what we deliver! Instead of using Zoom and a stack of external tools, our product provides an integrated and customizable set of rooms, control over logic and rules for transition between them, and integrates many engaging tools.

Initially, we are using our platform to deliver systems for governments (virtual court hearings) and to handle training (see our short promotional film:

If you want to work with a system that supports real time user actions, you enjoy working on concurrent operations, and you value well-modeled code, then join our team!

One last thing – lots of companies say they only hire the best. In our team, we have winners of the IT Olympics, a leading DDD trainer in Poland, the author of one of the best books on modeling, and a developer who previously worked on the largest distributed cache in the world (you have probably used it quite often if you watch movies or vloggers on a website starting with “YouT ..”.
