Responsibilities

• Good level of English.

Conditions

• Hybrid work format—cozy offices in Limassol, Paphos, or Warsaw. Remote work is up for discussion;

• Flexible schedule—work at your own pace as long as you stay in touch with the team and get things done on time;

• Support for self-development—free English & Polish (or Greek) courses, conference and course reimbursements;

• Health benefits—medical insurance for you and your family, plus a sports allowance;

• Top-tier equipment—we’ll set you up with the best devices for a smooth workflow;
