• If both sides are happy and it turns out you feel in the project like a kangaroo in Australia, we’ll agree on further cooperation terms and your growth direction. The sky is the limit!
• To start, we propose a B2B contract: PLN 18,000–27,000 net (depending on experience* and domain knowledge) plus work equipment. After the probation period, we will decide on further cooperation terms based on a joint analysis of tasks, growth direction, and the skills gained.
