About the project

This is how we organize our work

What we offer

• Learning & development opportunities – after your probation period, you’ll have access to a highly flexible and generous English language reimbursement program, along with an individual development budget to use as you see fit.
• Classic benefits like private medical care, a sports card, and a preferential life insurance plan. Plus, our infamous Fruit Tuesdays and a special summer bonus – ice cream.
• A hybrid work setup with plenty of flexibility. Delivery teams work mostly remotely. Support teams come to the office at least once a week – as an HR team, we meet every Wednesday. On other days, you decide where you work.
• A bunch of non-work activities, including Office Day (a fun-filled day when employees from all over Poland gather at the office), POP UP integrations, various competitions from cooking to photography, and the chance to submit charity causes to our CF4GOOD program, which provides support to those in need.
• A workplace that values people and is built on collaboration, not competition. If you’re tired of toxic work environments, you’ll finally get a chance to breathe. And if you’ve been lucky with great employers so far, we’ll do our best to keep that streak going.
