About the team

BUX Crypto aims to be the most reliable and user friendly crypto exchange service in Europe. As part of BUX, the largest neobroker in Europe, we want to help everyone do more with their money. 

To achieve this we need the help of an experienced, ambitious and open minded backend developer that’s interested in performant real time systems to help us achieve our goals.

We’re a small (6 people), very experienced team of developers with a diverse background. You’ll join a unit that’s open, supportive and values building human connection while building good software. We inspire each other to join discussions, like practical solutions and take our work seriously.

We’d appreciate it if you take a look at the BUX Culture book and the apps BUX Zero and BUX X. As we continue to grow, we will merge more of our technologies.
