• Full working day with a flexible and animated schedule for you, because the main focus is the result, not the time or place;
• A comfortable, stylish and sunny office with a view of the city center (Pushkinska str) and the opportunity to work at home when you feel not so full of beans or just moody or lazy (with a generator and battery installation 🇺🇦);
• Lack of bureaucracy, regular feedback and support from colleagues;
