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\nAt Nubank, software engineers sit at the intersection of data, intelligence, and scale. We build systems that process millions of decisions daily, from fraud detection to credit modeling and increasingly, we do this powered by AI. Machine learning is embedded across our core products: in how we assess risk, personalize experiences, and automate decisions at scale. Engineers here don't just consume AI capabilities; they help shape how intelligence is built, deployed, and maintained in production.\nWe do it with engineering rigor, autonomy, and a deep focus on impact. Our engineers work across the full spectrum: designing data pipelines and architectures, deploying and maintaining ML models in production, and building the distributed systems and platforms that power our products. We value small, independent teams that move fast, own their decisions end-to-end, and hold themselves to a high bar for quality and craft.\nWe strive for state-of-the-art software development practices across our entire stack. While we value candidates familiar with our technologies, we're confident that engineers who join Nubank will learn and grow alongside our team:\nHorizontally scalable microservices written mostly in Clojure, leveraging functional programming and hexagonal architecture\n\nHigh-throughput event-driven architectures for inter-service communication\n\nContinuous Integration and Deployment into cloud-native infrastructure\n\nDistributed transactional systems built on Datomic, modeling complex business domains with immutable data and strong consistency\n\nModern data platforms built on ETL/ELT best practices, with robust monitoring and observability\n\nOur Software Engineers\nWork with large scale distributed systems\n\nCollaborate with building microservices\n\nDesign, build and maintain robust data pipelines, distributed systems and ML-enabled solutions, ensuring reliability, scalability and performance at scale\n\nDeploy and maintain ML models in both batch and real-time scenarios, integrating them with other systems and monitoring through operational and business metrics\n\nLead data and engineering projects end-to-end - from requirements gathering and stakeholder alignment to delivery and iteration\n\nContribute to the design, documentation, maintenance and optimization of our data codebase, platforms and tooling\n\nTranslate business needs into data products and technical solutions aligned with Nubank's architecture and long-term strategy\n\nPartner with technical and business stakeholders to define strategies and deliver high-impact solutions\n\nShare knowledge, mentor peers and contribute to engineering and data literacy initiatives across Nubank\n\nWhat We're Looking For\nDeep programming experience in one or more general-purpose languages (e.g. Python, Clojure, Scala, Java), with a track record of guiding technical decisions and raising engineering standards\n\nExperience designing analytical data environments and data engineering solutions: pipelines, ETL/ELT, and data modeling\n\nUnderstanding of ML model lifecycle, from training and evaluation to deployment and monitoring\n\nExperience guiding the technical design of distributed systems, microservices and asynchronous architectures\n\nStrong communication skills to influence and align both technical and business stakeholders\n\nPassion for building and leading the delivery of high-quality software and data products\n\nNice to Have\nExperience with cloud platforms such as AWS, GCP or Azure\n\nKnowledge of data architecture patterns (Data Lake, Data Warehouse, Data Mart)\n\nFamiliarity with ML frameworks and feature engineering pipelines\n\nExperience with data visualization tools (Looker, Power BI, Tableau or similar)\n\nKnowledge of software engineering best practices: testing, clean code, documentation\n\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, Medical Plan and Dental Plan\n\nNuLanguage - Language Course Program\n\nNucleo - Our learning platform\n\nExtended Parental Leave, Daycare Allowance and Parental Consultancy\n\nWork-from-home Allowance\n\nGym Partnerships\n\n30 days of paid vacation\n\nRelocation Assistance Package, if applicable\n\nWork Model\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. \nFor more details, visit building.nubank.com/nu-hybrid-work-model/\nOur recruitment process may involve the use of artificial intelligence-enabled tools, such as automated interview transcription and analysis, to support the evaluation process. Artificial intelligence is not used to make final hiring decisions; all decisions are made by human reviewers.\nTo maintain a consistent and fair process for every candidate, Nu does not provide individualized technical feedback.
