  • Knowledge of mobile observability, monitoring, and debugging tools.
  • Strong communication skills in English, with the ability to explain complex concepts to diverse audiences.
  • Track record of delivering results in ambiguous, fast-paced environments.

Nice to Have:

  • Experience with backend technologies, especially those integrated with mobile applications.
  • Familiarity with distributed systems and large-scale app architecture.
  • Contributions to internal SDKs, libraries, or mobile design systems.
  • Understanding of user authentication, session management, and app state handling.
Why Join Us
  • Impact at Scale: Help shape the mobile experience for millions of customers across multiple countries, with the goal of reaching billions.
  • Technical Leadership: Influence the architecture and foundational technologies that all Nubank engineers rely on.
  • Innovation-Driven Culture: Work in a dynamic, collaborative environment that values experimentation, continuous improvement, and engineering excellence.
  • Career Growth: Develop as a strategic engineering, working on complex technical and organizational challenges.
