  • Knowledge of Scrum – as an organization we use this agile framework. It’d be nice if you at least knew the basics. If you don’t, willingness to learn will do.


  • Positive atmosphere at work – we are a small company and for that reason, we select our new colleagues carefully to build coherent company culture and feel comfortable at a place where we spend 30% of our lives.
  • Lack of boredom – we create diverse digital products for clients from around the world. Sometimes it is an advanced e-commerce platform, a mobile app, a smart TV experience, smart home equipment, and sometimes an industrial control system for a power plant.
  • A salary proportional to your qualifications – above all, we appreciate real skills and commitment. You will get additional points for being a friendly colleague. We are not very big fans of egos and FYPM attitude.
  • Personal development funds – we always try to stay up to date. Sometimes we organize training courses on our own and sometimes we simply participate in one. As a company, we believe in a permanent self-improvement.
  • Remote work – once a week is totally fine.
  • Apple hardware at work – a small thing, but can make one happy.
