Engineering at Nubank

We strive for state-of-the-art software development practices that currently include a variety of technologies, such as Clojure, Datomic, Kafka, Flink, Java, Spark, Scala, and AWS infrastructure. While we value candidates who 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.

At Nubank, one of our engineering principles is "Leverage Through Platforms". We build platforms that are customer-focused, product-driven, and designed for simplicity and usability. We believe in creating platforms that are demonstrably easier to leverage and outperform on value, cost, and experience than it would be to build a custom solution. Our platforms are built from working code solving real business needs, and we structure our teams to include all the necessary roles to ensure ownership and success.

As a member of the Nubank Data Platform, you'll play a crucial role in building and maintaining the core data infrastructure that powers our business. You'll work alongside talented engineers to design and implement solutions that provide the data processing capabilities of the Nubank data environment, empowering Nubankers to create, update, and generally manage data. Your contributions will directly impact the reliability, scalability, and accessibility of data, enabling them to make data-driven decisions and build innovative products that improve the lives of our customers.

As a System Engineer in the Data Business Unit, we expect you to demonstrate:

• Deep interest in building scalable data platforms and solving complex backend and infrastructure challenges, especially when it comes to managing the lifecycle of hundreds and hundreds of data processing clusters that run daily
• Experience with containerization and orchestration (Docker, Kubernetes, ECS, EKS)
• Solid understanding of Linux, file systems, and networking
• Experience with functional programming or willingness to learn
• Enthusiasm to check lower-level details
• Strong problem-solving and troubleshooting skills in complex environments
• Excellent communication skills, as we work in cross-functional, cross-team projects that have a global impact
• Autonomy and proactiveness, as you'll be responsible for designing and implementing data processing solutions, and solving complex problems.
• Great collaboration skills, pitching, and listening to different ideas within the team to reach amazing results. – We value collaboration, resilience, and a passion for sharing knowledge.

We’re looking for individuals who are passionate about what they do and eager to solve complex problems at scale – all this while working in a safe, welcoming environment. We seek people who want their work to have a positive impact on the lives of millions of people who, otherwise, would be stuck in a bureaucratic and inefficient relationship with their money.

If you are excited to develop even further in those areas, we might be a great match!

What we have to offer

• A working environment that always strives to favor a good work-life balance.
• A multidisciplinary and multicultural team.
• Technical challenging environment, which will help you grow in your career along with close support from many tenured engineers.
• Exciting problems to solve, especially given the scale at which we operate: We enable hundreds of thousands of Data Processing Jobs to be executed, with hundreds of Petabytes of data being stored every day.
• An amazing team of extremely collaborative people.
• Opportunity to positively impact several Business Areas across Nubank through data integration solutions. Billions of events, petabytes of data, and millions of dollars are on our day-to-day conversations on all our projects.
