ABOUT THE ROLE

Every transaction at Nubank travels across a network before it reaches a customer. As we grow across countries, accounts, regions and hybrid environments, the connectivity layer underneath has to stay fast, segmented, auditable and cheap to run — while never becoming the thing that takes the platform down.

As a Senior Software Engineer on a Cloud Network platform engineering team, you set and evolve the technical direction for how Nubank connects its cloud, hybrid and on-premises environments. You own problems whose scope spreads across several teams and business units, and you are expected to bring structure to ambiguity rather than wait for it to be resolved for you.

YOU'LL BE RESPONSIBLE FOR

- Setting and evolving the technical direction of the cloud network platform owned by your team, aligning with Nubank's canonical approaches and contributing back to the broader technical community.

- Support complex network projects and processes end to end — working independently, coordinating across subjects and stakeholders, and escalating for managerial support in a timely way rather than reactively.

- Proactively reducing long-term complexity through simplification, consolidation, deprecation and paved roads, explicitly balancing scalability, maintainability and cost, and considering both human and AI interaction with the platform.

- Owning the operational health of the network platform in your team's scope: leading complex incident response (diagnosis, coordination, resolution), driving complex postmortems, and owning the short- and long-term tech debt strategy that comes out of them.

- Promoting a culture of safe change — feature flags, gradual rollout, monitoring, fast rollback — applied to network changes, and driving simplification and cost optimization across the topology.

- Setting and enforcing quality standards for the team's automation and infrastructure code: testing practices, code review bar, reusable modules, and anticipation of quality and maintainability needs coming from business strategy.

- Defining observability for the platform — robust monitoring, controls and SLAs that surface issues proactively rather than after customer impact.

- Bringing a strong end-to-end domain understanding: tracing a business process from product through the transactional path down to the network and data layers, and understanding how network design choices propagate through it.

- Owning the network security posture of your scope, including PCI DSS or equivalent standards, segmentation, and controls that hold up under audit.

- Evaluating buy vs. build options and new products and technologies, being data-driven about stability, reliability, scalability and cost before committing to a solution.

- Participating in hiring as a core part of the role, contributing to function-wide taskforces and initiatives, and documenting decisions so that knowledge travels across teams, not just within yours.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
