Our Engineering Team

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.

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.

What challenges you will find as a Systems Engineer  

Here at Nubank we treat infrastructure and operations as Software Engineering problems. It's expected of a Systems Engineer to have solid programming skills coupled with background on networks and operating systems. We consistently work with new technologies and thus value professionals who are open to learning new things, regardless of pre-existing comfort zones.

Some of the problems you'll encounter:

Tune JVM parameters and set the strategy for JVM tuning for 350+ microservices deployed across 10+ infrastructure shards

Automate and incrementally improve databases and microservices provisioning;

Scale systems efficiently through configuration tuning and/or major architectural changes;

Orchestrate containers and maintain a highly available platform with Kubernetes;

Provision AWS resources in a programmatic manner through SDKs;

Troubleshoot/debug performance issues and architectural bottlenecks;

Cultivate a culture of observability and monitoring.

Relevant experience

JVM Tuning and Interop (GraalVM, JDK11, Azul, Profilers)

Infrastructure as code and Container orchestration (e.g., CloudFormation, Ansible, Terraform, Kubernetes, ECS, Mesos)

Amazon Web Services (EC2, DynamoDB, ElastiCache, S3, IAM, CloudTrail)

Monitoring and Culture of Observability (Prometheus, Grafana, NewRelic, InfluxDB, Librato)

Proficiency in at least one high-level scripting language (e.g. Python, Ruby)

Don't worry if you don't know all of it! Having experience in some of it and being willing to learn is enough to apply.

You will have a meaningful chance to shape architecture, process, and culture while working with bleeding-edge  technologies. We believe in good team chemistry, enthusiasm for building things, and our surprising capacity to learn new things when we stay humble and open-minded. Good computer science skills and concepts as well as English language skills are helpful.

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.
