Systems Engineer (SRE/DevOps)
Why is Software Engineering important for Nubank?
Nubank is a technology company, and software engineers form the bulk of our team. Also, our infrastructure is growing in sophistication, complexity, scale and particularly with respect to managing data for analysis and machine learning, robustness and observability. We are looking for engineers that can help with the challenges around provisioning and operating such architectures.
What are some examples of problems a Systems Engineer will solve?
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:
- Automate and incrementally improve databases and microservices provisioning;
- Scale systems efficiently through configuration tuning and/or major architectural changes;
- Provision AWS resources in a programmatic manner through SDKs.
- Troubleshoot/debug performance issues and architectural bottlenecks;
- Cultivate a culture of observability and monitoring;
You will fit well if:
- You are results-oriented and enjoy shipping new features
- You are hungry and enjoy being constantly challenged to learn and do more
- You aren't afraid of crossing abstraction boundaries to go deep into the root cause of an issue
- You embrace conflict of ideas and like to question the status quo
- You learn fast and easily adapt to changing situations and priorities
- You enjoy operating a dynamic, large scale, complex environment
- You want to understand the big picture, to be held accountable and make a meaningful contribution with your work
- Infrastructure as code (e.g., Docker, CloudFormation, Ansible, Terraform)
- Amazon Web Services (EC2, DynamoDB, ElastiCache, S3, RDS, ELB, ASG, IAM, CloudWatch, SNS, CloudTrail, Config)
- Networking and tooling on Linux/Unix-like environments (tcpdump, netstat, iperf, nmap, traceroute, iptables)
- Microservices environments and CI/CD pipelines (Go CD, CircleCI, TravisCI, Jenkins, CodePipeline)
- Large scale operations with Kafka and Zookeeper
- SQL / NoSQL databases (Datomic, AWS Redshift, PostgreSQL)
- Monitoring and Culture of Observability (Riemann, InfluxDB, Grafana, Kapacitor, Zabbix, Librato)
- Proficiency in at least one high-level scripting language (e.g. Python, Ruby)
- Functional Programming Languages (Clojure, Scala, Haskell)
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. An engineering or computer science undergraduate degree and English language skills are helpful.
