(Remote) Senior Backend Engineer

Permanent employee, Full-time · Mexico

What does KLAR do?

Klar is a Mexican fintech startup whose mission is to democratize and revolutionize the way in which financial services have been delivered so far in Mexico, especially since half of the population doesn’t have a bank account. We have had more than 1 million users since 2021!

We are changing this scenario by offering a tech product that allows users to manage their money through a mobile and web application. Users can withdraw or deposit money from any cash machine, they can also use the card in stores and even do online payments. We don’t have any branches, everything is done and managed through the app. 

Our product roadmap includes offering loans and credit for a larger group of clients based on our very sophisticated credit modeling. 


Life at Klar

We have a very international team with more than 30 nationalities working from Mexico City, Berlin, and remotely. Our founder Stefan Moller is also half German and Mexican, which allowed Klar to think globally since its inception. 


This position is available onsite in our Mexico office or remotely within a similar time zone.
