Every transaction at Nubank travels across a network before it reaches a customer. As we grow across countries, accounts and regions, the connectivity layer underneath has to stay fast, segmented, auditable and cost-efficient, without ever becoming the thing that takes the platform down.

As a Senior Cloud Network Engineer on our Cloud Network platform engineering team, you will design, build and operate the cloud network that Nubank’s engineering teams rely on. You will treat the network as software: automated, tested and versioned. This is an IC5 role: you lead through technical depth, design quality and influence, not direct reports. You will be part of a global engineering organization and work with teammates across countries, so collaboration in English is part of everyday work.

You’ll be responsible for

Designing and evolving connectivity patterns across multi-account, multi-region and hybrid-cloud topologies, making sound architectural decisions in designs that span multiple teams.

Building and maintaining the network platform as code (Terraform or similar), with strong standards for testing, code review and reusable modules.

Owning the operational health of the platform in your scope: leading incident response, driving postmortems and following through on the tech debt they uncover.

Promoting safe change on the network: gradual rollouts, monitoring and fast rollback.

Defining observability for the platform, with monitoring and SLAs that surface issues before customers feel them.

Owning the network security posture of your scope, including segmentation and standards such as PCI DSS, with controls that hold up under audit.

Simplifying the topology over time through consolidation, deprecation and paved roads, balancing scalability, maintainability and cost.

Evaluating build vs. buy decisions with data on stability, scalability and cost.

Mentoring other engineers, taking part in hiring, and documenting decisions so knowledge travels across teams.
