Lead Software Engineer (Cloud Network)

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.

Leading high-level and low-level design for connectivity patterns across multi-account, multi-region, multi-geo and hybrid-cloud topologies, independently making sound architectural decisions in multi-component, multi-team designs.

Managing 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.

Mentoring IC4/IC5 engineers on the broader system landscape, design reasoning and operational practice, and raising the bar of the people around you.

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.

CCIE, CCNP or equivalent experience — you are comfortable designing, building, implementing, maintaining and troubleshooting complex, large-scale networking infrastructures.

Solid hands-on experience in infrastructure automation and cloud computing (AWS preferred), with depth in AWS networking services — Transit Gateway, VPC design, Direct Connect, PrivateLink, Route 53, NAT/egress patterns, network firewalls — or similar technologies.

Deep experience planning, deploying and troubleshooting network solutions at scale: IP address management, BGP and dynamic routing, firewalls, load balancers, routers and switches, and hybrid connectivity.

Strong coding skills (python, .Net. Java, Go etc.)

Experience leading incident response and root cause analysis for high-impact, ambiguous failures across team boundaries.

Strong leadership: you confidently lead complex projects that carry ambiguity and require strategic thinking, with or without formal authority.

Experienced communication: you convey complex technical messages clearly and persuasively to technical and non-technical audiences, adjusting depth and examples to the room, and you facilitate productive discussion rather than just presenting.

Strategic acumen and long-term perspective: you connect network platform decisions to business drivers such as operational efficiency, reliability and cost, link 6–12 month initiatives to the broader organizational strategy, and anticipate cross-team impact and trade-offs.

An analytical profile: you go after root causes and propose solutions that hold, working creatively and analytically in a continuous improvement environment.

English proficiency — able to read, write and lead discussions across time zones and language boundaries. Location for this opportunity (City, Country)
