You will lead complex, ambiguous, strategic initiatives from technical direction through production code, make high‑stakes architecture decisions, and set design and quality standards that other squads adopt. You’ll also mentor senior engineers, influence cross‑team strategy, and represent Nu in external technical discussions.
Extensive Staff‑level (or higher) experience designing, building, and operating high‑scale, mission‑critical systems, a proven record of leading cross‑org initiatives with little formal authority, strong hands‑on coding ability, and excellent communication of technical strategy. Fluency in English and a pragmatic, hands‑on approach to AI are required; payments, fraud, regulated environments, or functional programming experience are a plus.
Nu’s twelve‑year‑old platform underpins 140 million customers and is expanding into new markets, AI agents, and products; senior staff engineers shape the technical roadmap that drives this growth and ensures the platform remains scalable, reliable, and innovative. Their decisions directly influence business results and the organization’s ability to deliver new financial services.
Candidates who thrive in ambiguous, high‑impact technical leadership roles, enjoy building systems from scratch and evolving large existing codebases, can influence without authority, and are eager to mentor others while working in a hybrid office environment.

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.
