**Get to know our working methodology, the**
**Qonto Way**
- We highly value the analysis phase on software delivery placing a heavy emphasis on upfront technical designs, team reviews, and smart slicing (called Value Engineering). In this manner, you would be expected to put a heavy focus on Quality which we believe drives the velocity our customers need.
- We foster an environment that enables our engineers to be proud, therefore happy, of the work they are doing as we believe that this is the route to success.
- We think that success comes out of a space where you are given time, support, and authority to improve yourself, our systems, and our processes. Our lean toolbox enables you to monitor your constant improvements (Kaizen, PDCA) in a collaborative way with your peers and manager.
- Our engineers, working in cross-functional teams writing mostly in Golang and Ruby, dedicate themselves to one feature at a time (we call this One Piece Flow).

- Work in a **multicultural fast-paced environment** with a strong focus on quality
- **Build robust products** and improve features used by 220K+ clients across Europe
- Have a **strong impact on business decisions** as part of a Cross-Functional Team (our Back End engineers work commonly with other departments on a topic in order to provide the best solution in terms of efficiency and productivity).
- **Keep learning and improving**: a various range of training, peer programming sessions with our Experts, possibility to learn a new programming language (Ruby, GO...)
- **Share knowledge** among the whole tech and product team (internal and external talk, weekly meetings, Tech Monthly) and the community (articles, meetups)
