Why Jooble?

Work format
Flexibility is not just a word for us. In Kyiv, we work in a hybrid format, combining office and remote work. In other cities and countries, you can work fully remotely. No matter where you are, we’ll make sure you feel comfortable and productive by providing all the necessary equipment.

Schedule
You decide when to start your 8-hour workday — anytime between 8:00 and 10:00 a.m. Kyiv time. The key is to stay connected and plan time for team meetings. We value the freedom to organize your day while believing that a shared rhythm helps us work more efficiently.

Growth and development
At Jooble, everyone has a dedicated budget for personal and professional development. It’s your space to gain new knowledge and skills that help you grow — and make the company stronger at the same time.

Physical and mental health
Health is an essential part of both work and life. At Jooble, we offer full medical insurance (after 3 months of employment), and for colleagues abroad — financial support for medical expenses. We also cover consultations with psychologists through our wellbeing service or reimburse 50% of the cost if you choose your own specialist.

Rest and recovery
You’ll have 24 working days of annual paid vacation + 6 additional recharge days. 20 paid sick days + 4 days without medical confirmation — so you can take time to recover when needed. In addition, you’ll get 6 fixed public holidays off.

Team
At Jooble, you’ll work alongside strong professionals and experts who grow together and create global-level solutions. Everyone has a voice and can influence processes. We value honest feedback and look for people who share our values.

Support for Ukraine
At Jooble, we preserve jobs for mobilized colleagues. As a team, we actively participate in initiatives that support Ukraine, and our product is designed to help even more people find jobs — especially during challenging times.
