The Opportunity
Building the Bedrock of Nubank's Future
Nubank was built on bold technical choices: emphasizing simplicity, immutability, and state-of-the-art concurrency as the foundation for a global financial revolution. Today, as we scale to serve our customers globally and enter a new era of AI-driven engineering, we are doubling down on our commitment to foundational technical excellence.
As a Library Architect, you will take ownership of the core programming language ecosystem and shared abstractions that power our backend microservices. This role will oversee, govern, and elevate Nubank's foundational infrastructure architecture.
You will help define the "Nubank Way" of building resilient core software libraries and oversee how they interact across the bank's broader programming language landscape. You will ensure that our internal libraries—which support 4,000+ microservices—are stable, idiomatic, and maintained to the highest standards.
