Nubank Senior Staff Software Engineer at Nubank responsible for leading complex strategic initiatives and setting technical direction. Deliver scalable solutions and influence architecture and standards across teams.
Responsibilities
Nu 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.
We’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.
YOU’LL BE RESPONSIBLE FOR
Leading complex, ambiguous, strategic initiatives end to end, from setting the technical direction through to code running in production.
Spotting the problems worth solving in your area and delivering scalable solutions that change business results and strategy, not just roadmap items.
Shaping your area’s mid- to long-term strategy with product and business leaders, then turning it into a technical roadmap others can build on.
Making high-stakes architecture decisions where no clear precedent exists, and guiding teams through the trade-offs.
Setting standards beyond your own team, including design guidelines, quality bars and reusable components that other squads adopt.
Mentoring senior engineers, managers and peers across teams. You’ll also take part in hiring and lead or sponsor guilds.
Representing Nu in technical conversations with external partners, platforms and vendors.
