Senior Backend Engineer (Python/APIs) - remote

Posted 3 years ago  • São Paulo, Brazil

A little bit about us:

We are Belvo, a financial API platform with the bold vision of democratizing access to financial services in Latin America. We enable any company or developer to access and interpret their end-users’financial information. We are turning the rich and diverse Latin American financial ecosystem into a set of developer-friendly tools and APIs.

We’re a highly-technical, passionate and driven team. We are currently 70 people, projected to be 100+ by the end of 2021. Our team currently represents 15 nationalities and we have offices in Barcelona, Mexico City, and São Paulo - while a large portion of us works remotely.

We are tackling a very challenging problem: connecting fintech innovators with legacy financial infrastructure. We strive to go beyond the limits of what is possible today and to do so in an elegant and developer-first way.


Since starting our adventure in May 2019, we have raised $56m from the leading VC investors globally.

  • We are pragmatic and customer-focused. We strive to find the right set of trade-offs in order to validate our hypothesis as early as possible, iterating on our products based on customer feedback.
  • We communicate transparently. We do weekly all-hands where we get together to discuss company performance and goals.
  • We are a flexible international team focused on creating cool stuff. Some of us prefer to work together in one of our offices and others prefer remote.

  • Build excellent documentation, SDKs, client libraries. Continuously improve the "developer experience" of Belvo's platform.
  • Be customer-focused, think as a user of our APIs. Proactively tackle potential improvements and customer pain points.

  • Track record of producing A-grade documentation for public consumption

Our tech stack:

  • We primarily use Python on the backend. We use battle-tested technologies such as Django, and we are heavy users of Python’s asyncio for some parts of our stack
  • We use Javascript, Vue.js and Sass on the frontend. We are developing and leveraging our own design system and component library
  • We run our infrastructure on top of Amazon Web Services, leveraging managed services. We tend to favor the use of managed services wherever possible, in order to focus on our business problems
