The company has been leading an industry transformation through innovative products and human-centered services.\nProprietary 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.\nVisit our Institutional Page\nAbout the role\nEvery 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.\nAs 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.\nYou'll be responsible for\nSetting 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.\n\nSupport 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.\n\nProactively 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.\n\nOwning 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.\n\nPromoting 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.\n\nSetting 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.\n\nDefining observability for the platform - robust monitoring, controls and SLAs that surface issues proactively rather than after customer impact.\n\nBringing 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.\n\nOwning the network security posture of your scope, including PCI DSS or equivalent standards, segmentation, and controls that hold up under audit.\n\nEvaluating buy vs. build options and new products and technologies, being data-driven about stability, reliability, scalability and cost before committing to a solution.\n\nParticipating 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.\n\nWe are looking for a person who has\nCCIE, CCNP or equivalent experience - you are comfortable designing, building, implementing, maintaining and troubleshooting complex, large-scale networking infrastructures.\n\nSolid 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.\n\nExperience planning, deploying and troubleshooting network solutions at scale: IP address management, BGP and dynamic routing, firewalls, load balancers, routers and switches, and hybrid connectivity.\n\nStrong coding skills (python, .Net. Java, Go etc.)\n\nExperience leading incident response and root cause analysis for high-impact, ambiguous failures across team boundaries.\n\nStrong leadership: you confidently lead complex projects that carry ambiguity and require strategic thinking, with or without formal authority.\n\nExperienced 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.\n\nStrategic 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.\n\nAn analytical profile: you go after root causes and propose solutions that hold, working creatively and analytically in a continuous improvement environment.\n\nEnglish proficiency - able to read, write and lead discussions across time zones and language boundaries.\nLocation for this opportunity (City, Country)\nSão Paulo, Brazil Campinas Rio de Janeiro Belo Horizonte\nOur Benefits\nChance of earning equity at Nubank\n\nFood/Meal Card (Vale-Refeição and/or Vale Alimentação)\n\nPublic Transportation Commuting Benefit (Vale-Transporte)\n\nNuCare - Psychological, Financial and Legal Assistance Program\n\nLife Insurance\n\nMedical Plan\n\nDental Plan\n\nNuLanguage - Language Course Program\n\nNucleo - Our learning platform of courses\n\nExtended Parental Leave\n\nDaycare Allowance\n\nParental Consultancy\n\nWork-from-home Allowance\n\nGym Partnerships\n\n30 days of paid vacation\n\nRelocation Assistance Package, if applicable\n\nWork Model for this Role\nHybrid 2-3 times/week: Our hybrid work model brings us to the office at least twice a week, on strategic days designed to maximize team connection and collaboration.
