Sobre a vaga

Data Platform at Nubank
We strive for state-of-the-art data engineering practices and that currently includes a variety of technologies. While we value candidates who are familiar with them, we are also confident that data engineers interested in joining Nubank will learn from our team.



A multi-cloud data platform that is built under the funcional engineering paradigm.
In order to have a very democratic data environment, we use platforms like Databricks, BigQuery, and Looker to provide a complete data experience for a big and very broad audience with many levels of data-literacy. Currently, more than a thousand nubankers use our platform on a weekly basis.
Horizontally scalable microservices 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 process-light organization that values human interactions. We value working in small, independent teams that feel like small startups within the company, and avoid coupling and centralizing where realistic. We understand that execution is the key to success and optimize processes to remove bottlenecks.
You can read more about it in our engineering blog and get some insights into how we work.



Nubank Data Engineers in the Data Platform will solve the following problems
Work on a self-service BI platform that powers all data-assisted decisions across Nubank
Refine the data platform to enable a broader set of data applications such as streaming systems
Improve user-experience and platform predictability through work on monitoring, automation, and system reliability
Remove bottlenecks and improve performance, at times by redesigning critical components from scratch
Triage bugs and exceptions reported in production and conduct system load/stress tests
Identify potential vulnerabilities and implement controls to deal with them


Once here, you will have
Hands-on experience building and operating a large-scale BI environment, from the multi-cloud data transfer between AWS and GCP to the administration of the data tools.
A deep understanding of how to administrate and enable BI data tools (e.g. Databricks, BigQuery, Looker) in a multi-cloud environment with thousands of users, tens of thousands of datasets, and petabytes of data. Batch and Stream.
Experience providing an effective BI platform to address a multitude of use cases for people with diverse backgrounds in data.
Passion for making the inner workings observable and experience improving stability and performance.
Experience with a distributed architecture built with Clojure under the functional paradigm and relying on an intense use of Kafka.


Experience with the following is desirable
You don't need to have it all because you will learn a lot here, but we are looking for people with experience in the following areas:

Operating systems with high stability and security requirements
Administering platforms as BigQuery, Databricks, or Looker
Monitoring and logging tools (like Prometheus, Splunk, and Grafana)
Writing and operating production-ready services in a functional programming language (like Clojure)
Experience with administration of BigQuery and Data Studio over GCP is a plus

We expect you to
Thrive in dynamic, fast-paced, results-oriented teams
Be hungry and enjoy being constantly challenged to learn and do more
Embrace conflict of ideas and question the status quo
Learn fast and easily adapt to changing situations and priorities
Believe in building great products and doing great work
Understand the big picture, be held accountable, and make a meaningful contribution with their work
