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 ourInstitutional Page\nABOUT THE ROLE\nNu runs a twelve-year-old platform that has never stopped growing: thousands of microservices, low-latency payment rails, large-scale data platforms, machine learning in the critical path, and one mobile app carrying a dozen financial products across several regulated markets. We are expanding into new countries, new lines of business and new interfaces, including AI agents that act on customers’ behalf. Many of the systems we need for that don’t exist yet.\nWe’re hiring Senior Staff Software Engineers to be the technical reference for an area of the business. You’ll find the problems worth solving, design and ship the solutions, and raise the bar for the teams around you. If Staff is about making a team succeed, Senior Staff is about making an organization succeed. You’ll be matched to a specific team based on your depth and interests. Current areas include agentic and AI-native banking, payments and money movement, fraud, identity and risk, core banking, and platform and infrastructure.\nYOU’LL BE RESPONSIBLE FOR\nLeading complex, ambiguous, strategic initiatives end to end, from setting the technical direction through to code running in production.\n\nSpotting the problems worth solving in your area and delivering scalable solutions that change business results and strategy, not just roadmap items.\n\nShaping your area’s mid- to long-term strategy with product and business leaders, then turning it into a technical roadmap others can build on.\n\nMaking high-stakes architecture decisions where no clear precedent exists, and guiding teams through the trade-offs.\n\nSetting standards beyond your own team, including design guidelines, quality bars and reusable components that other squads adopt.\n\nMentoring senior engineers, managers and peers across teams. You’ll also take part in hiring and lead or sponsor guilds.\n\nRepresenting Nu in technical conversations with external partners, platforms and vendors.\n\nWE’RE LOOKING FOR SOMEONE WHO HAS\nRequired\nExtensive experience at Staff level or above (or equivalent) designing, building and running high-scale, mission-critical systems.\n\nA track record of leading initiatives across organizational boundaries with little formal authority, and of seeing them land.\n\nEvidence that you ship. You still write code and validate architecture in production.\n\nStrong judgment in ambiguous situations, and a history of building systems from scratch as well as evolving large ones you inherited.\n\nThe ability to explain complex technical strategy clearly to engineers, product partners and senior leadership, and to build alignment around it.\n\nA pragmatic, hands-on approach to AI. You use it to get more done, and you measure what it actually delivers.\n\nProfessional fluency in English.\n\nNice to have\nExperience in payments, card networks, fraud and risk, or digital banking.\n\nExperience building consumer-facing products at scale, with real product and UX sensibility.\n\nExperience in regulated or otherwise unforgiving environments, where correctness matters more than speed.\n\nExperience with LLMs, agent platforms or protocols such as MCP.\n\nPortuguese or Spanish.\n\nClojure or functional programming experience. It’s our primary backend language, but it isn’t required: every engineer goes through an immersive Clojure onboarding.\n\nLOCATIONS\nPalo Alto, CA, USA · Miami, FL, USA · McLean, VA, USA · Toronto, ON, Canada · São Paulo, Brazil\nWORK MODEL\nThis is a hybrid role, requiring attendance in the office 3 days per week.
