Reasons Why You Would Enjoy Working With Us

  • We organize TechTalks, meet-ups and create guilds where we exchange knowledge - you can learn a lot from your teammates.

  • We have a close-knit team and we make sure to have regular integrations - we often go out to celebrate together.

  • You can work remotely or choose to work from our offices in Wroclaw or Bielsko-Biala. However, we count on your openness to occasionally visit the office for team meetings or client visits, or possible occasional trips to the client's headquarters.
