What are some examples of problems a software engineer will solve?

Shipping valuable features requires close coordination between devops, database, API, frontend, and mobile workstreams; Nubank engineers commonly pair and rotate focus between these responsibilities. We consistently work with new technologies, and thus value professionals who are open to learning new things, regardless of pre-existing comfort zones. Nubank mobile software engineers might solve any of the following problems:

  • Ship new features for the mobile apps using modern languages like Swift and Kotlin and participate in the transition to a cross-platform solution using Flutter.
  • Implement complex systems and evolve the application architecture based on reactive paradigms and with functional programming concepts.
  • Triage bugs and exceptions reported in production.
  • Have the opportunity to build backend micro-services in functional programming languages, such as Clojure and Scala.

What is it like working at Nubank?

Our teams work using agile frameworks to deliver great solutions for our customers. We emphasize pairing, controlling work-in-progress, and try to adapt our team structures and processes to suit the particular working styles of the engineers within those teams.

Our working environment is open and diverse, and our offices have a broad mix of collaborative working spaces, quiet areas, leisures space, and workstations.

Overall, we want our engineers to be comfortable at work: we don’t have a dress code and you can work wearing shorts and flip-flops. We also have a pet-friendly office: you may bring your furry friend to work.
