About October 

October (www.october.eu) is a leading European data-driven FinTech company. Our mission is to finance businesses better. We change the way SMEs finance themselves, reduce their dependency on banks and deliver faster and better value than traditional players. We are passionate about making SMEs grow and have provided hundreds of millions of euros to thousands of European companies.


With October Connect, October is now bringing its digital lending expertise to financial institutions to better monitor their portfolio performance and enrich their risk analysis.


Our team currently consists of 100+ people in Paris, Madrid, Milan, Amsterdam and Munich. And we have the ambition of recruiting 50 more by 2022.


At October we believe that a great culture is fundamental to our success and therefore we put a strong emphasis on our company values.


Tech at October 

We think reinventing financing is a massive tech challenge, that’s why we built October as a tech and data-driven startup. Today, 15 developers are working on building the best financing experience ever made, very closely to the Product team.


We love JavaScript at October. That’s why every part of our stack is based on JS: we use Node.js (with some TypeScript) and MongoDB on the back-end, Ember.js on the front-end, and React Native on mobile. The platform runs on AWS, deployed using Terraform and Github Actions. You can take a look at our whole stack here: https://stackshare.io/october.


We believe in ownership and mentoring at October. By following good code practices and through code review, we make sure to deliver quality code and allow developers to grow their skills.


We follow the Scrum methodology: the Tech and Product teams are split in 3 squads, a 4th squad being built currently.
