Descrição da Vaga

Security Software Engineer


InfoSec at Nubank:

Nubank is a technology company and software engineers form the bulk of our team. We are a group of extremely passionate software engineers, with varying degrees of experience and diverse backgrounds responsible for improving our customers experience with the app and creating new features. InfoSec team is an engineering team, primarily focused on Security, that provides the security baseline for the whole infrastructure and engineering of Nubank, ensuring the customer is protected.

We believe in:

  • Good team chemistry;
  • Enthusiasm for building and delivering new features and products;
  • Capacity to keep learning new things while constantly improving what we are already good at;
  • Collaborating efficiently to ship quality products.

Our challenges:

Technology is not a sector of our business: it’s intrinsic to every area at Nubank. We encourage everyone to challenge the status quo. There’s no “innovation team” - we hire innovative people for all our positions and encourage them to constantly question decisions in order to keep finding better ways to do something. Our business is growing rapidly, and our engineering team must match that demand.

As we grow, we need to:

  • Find new techniques and technologies, multiplying efficiency through tools and libraries;
  • Balance new processes while staying agile;
  • Learn quickly and easily adapt to changing situations and priorities;
  • Sustainably scale diverse teams.


How do we work?

We strive for state-of-the-art software development practices, that currently includes a variety of technologies. While we value candidates that are familiar with them, we are also confident that software engineers who are interested in joining Nubank will be able to learn from our team.
* Horizontally scalable micro-services written mostly in Clojure, using Finagle and leveraging upon functional programming techniques and hexagonal architecture.
* High throughput jobs and inter-service communication using Kafka;
* Continuous Integration and Deployment into AWS;
* Storing data in Datomic and DynamoDB;
* Monitoring and observability with Prometheus;
* Running as much as possible in Kubernetes.

We are a very process-light organisation that values human interactions. We value working in small, independent teams that feel like small startups within the company, and eschew coupling and centralizing where realistic. We understand that execution is the key to success, and optimize processes to remove bottlenecks.

    ótima empresa para quem quer um ambiente dinâmico

    Brand Manager

    São Paulo, SP

    Prós: Participação no design das estratégias da empresa, autonomia, estrutura horizontal, time incrível e diverso e ambiente dinâmico repleto de aprendizados

    Contras: Por ser uma startup, alguns processos ainda estão em construção. O que é super legal para participar dos mesmos, porém pode ser penoso quando se trata de treinamentos e processos do time de People.

    Um dos melhores lugares que já trabalhei


    São Paulo, SP

    Prós: Uma empresa que sempre aposta e encoraja a experimentação de novas tecnologias. Dificilmente o trabalho se tornar monótono por estarmos em constantes mudanças. Assim como o produto é transparente com os clientes, a empresa é transparente com os funcionários. Os donos do Nubank são acessíveis e *não há* os clássicos cargos de chefia-desnecessária. É tudo muito profissional, a maioria das pessoas que trabalham para o Nubank fazem um serviço de primeira qualidade.

    Contras: A mudança constante em alguns momentos tem seu preço, por exemplo, já aconteceu de não terminarmos um projeto pois o foco mudou. Algumas vezes parece que estamos reinventando a roda. Existem algumas pessoas esnobes/prepotentes em cargos de liderança.

    Recomenda a empresa: Sim
