As a chapter, we identified a set of principles that guide behaviors we admire in each other and we pursue as a team:
  • Diverse ensembles don't overfit;
  • We reinforce each other's learning;
  • Mind the person behind the data point;
  • We share the same objective function;
  • We trust our confidence interval;
  • Pursue global maxima.

We know that executing is the key to being able to optimize processes and to reach success, so that's what we build our work model around.

Our team strives for cutting edge model development practices, which currently includes a variety of different technologies. While we value candidates that are familiar with the tools we use here, we are also confident that Data Scientists with good knowledge of other technologies and that want to join Nubank will be able to learn from our team.
