We are currently looking for software engineers with strong Craftsmanship to join our team and help us create an application that we are developing for a French startup in the fin-tech industry.

The client is a relatively new, Cash flow management company, founded in 2016 in the heart of France. With 120 million euros raised, since 2019 they have grown up to 200 employees across 5 countries, and more than 3500 clients, and a target of 10 000 clients by the end of 2022.

They are developing two new products (Payment integration) in which you will have a huge impact on the final product, helping to define its success making it a great place to work and grow along with the company.

They have established a true culture of software quality. They made sure to develop this culture from the beginning, and that it is now present at all levels of the team. This is why, even during sprints, they don't rush delivery and allocate 20% of their time to continuous improvement projects.
