Job description

About Nu

Nu serves more than 140 million customers, guided by a mission to fight complexity and empower people. The company has been leading an industry transformation through innovative products and human-centered services.

Proprietary technology and data at scale power Nu’s digital platform, built to promote financial access, advancement, and transparency. Its business model thrives on customer love and lower costs, feeding a flywheel of growth and profitability.

About the role

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.

We are looking for a person who has

• Production experience with public cloud networking, preferably AWS: Transit Gateway, VPC design, Direct Connect, PrivateLink, Route 53, NAT/egress patterns and network firewalls. Experience with Azure or GCP networking is also valued.
• Experience connecting cloud and on-premises environments: hybrid connectivity, BGP and dynamic routing, IP address management, load balancers and firewalls, planning, deploying and troubleshooting at scale.
• Coding and automation skills (Python, Go, Java, .NET), using infrastructure as code (Terraform or similar), Git, CI/CD and containers to build and operate network infrastructure.
• A background in network engineering, SRE, DevOps or software engineering. What matters is hands‑on public cloud networking experience.
• 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.
