We’re growing our team in Poland and want to be upfront about how this role is structured. As we don’t yet have a legal entity in Poland, we work with an Employer of Record (EOR) or umbrella company to onboard talent in the region. This means the role is offered on a fixed‑term basis via an international contractor agreement — and is fully remote.
