Why Join Us
What it's like working at JOE & THE JUICE? What better way than actually asking somebody who works in the development team? We've asked our team member, Valeriia, if she could describe what she finds great about working with us: "I love working at JOE & THE JUICE because the company has created conditions and environment that don’t force you to work extra hours, but you have the desire to do so.
No matter what position you hold, your opinion will be taken into consideration. Your team will become your new family, a new universe where you can remain yourself. The project you will work on is interesting with different technologies and you always have the opportunity to offer something new.
The company gives you space and the opportunity to develop and learn something new. Your mistakes won't become a bitter experience, but as steps towards a better version of yourself as a developer.
