Senior Cloud Network Engineer

The role

You will design, build and operate the cloud network that Nubank's engineering teams rely on, treating the network as software. You will work on multi-account, multi-region and hybrid-cloud connectivity, and lead through technical depth and design quality.

What you will do

• Design and evolve connectivity patterns across multi-account, multi-region and hybrid-cloud topologies.
• Build and maintain the network platform as code (Terraform or similar), with testing, code review and reusable modules.
• Own the operational health of the platform: lead incident response, drive postmortems and follow through on tech debt.
• Promote safe network change: gradual rollouts, monitoring and fast rollback.
• Define observability for the platform, with monitoring and SLAs that surface issues early.
• Own the network security posture of your scope, including segmentation and PCI DSS standards.
• Simplify the topology over time through consolidation, deprecation and paved roads.
• Evaluate build vs. buy decisions with data on stability, scalability and cost.
• Mentor other engineers, take part in hiring, and document decisions.

Required qualifications

• Production experience with public cloud networking, preferably AWS: Transit Gateway, VPC design, Direct Connect, PrivateLink, Route 53, NAT/egress patterns and network firewalls.
• Experience connecting cloud and on-premises environments: hybrid connectivity, BGP and dynamic routing, IP address management, load balancers and firewalls.
• Coding and automation skills (Python, Go, Java, .NET), infrastructure as code (Terraform or similar), Git, CI/CD and containers.
• A background in network engineering, SRE, DevOps or software engineering.
• Experience leading incident response and root cause analysis for high-impact failures that cross team boundaries.
• An analytical mindset focused on root causes and continuous improvement.
• English proficiency to read, write and lead discussions across time zones.

Nice to have

• Experience with Azure or GCP networking.
