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\nThis position is for an IC7 Mobile Software Engineer to join the Data Intelligence Squad inside the AI Core BU.\nAbout AI Core\nAI Core is the business unit helping make Nubank an AI-first company. Its mission is to power key decisions and customer interactions on a shared platform that gets smarter with every transaction and conversation. In practice, AI Core sits at the intersection of predictive intelligence, AI-native customer experiences, and platform building: from foundation models that improve credit, risk, pricing, and recommendations, to products like AI Private Banker, to the underlying data, orchestration, and infrastructure that let intelligent systems operate at scale.\nThis is a uniquely high-impact moment for the BU. AI Core is building the foundations that allow Nubank to solve high-value problems with AI, raise the quality of models and responses, and turn promising ideas into production-ready products faster.\nAbout the Data Intelligence Squad\nData Intelligence is the horizontal data layer that powers Foundation Models and GenAI at Nubank. It unlocks Nubank's data ecosystem by orchestrating, enriching, and serving the signals that help us understand each customer more deeply.\nWe work across the entire ML lifecycle, from building data pipelines and preparing high-quality signals to enabling machine learning experimentation and model improvement.\nWe're now expanding our scope to customer data collection through the Nubank app - and that's where you come in.\nAs an engineer on the Data Intelligence Squad, you'll lead efforts to collect additional device metadata from customers - for example, by integrating third-party SDKs into the app. This data will power improvements to our Foundation Models - which drive high-impact use cases across the company, including credit and lending models - and will underpin new product lines such as Location Intelligence.\nWhat we're looking for\nAn IC7 Mobile Software Engineer with more than 6 months of tenure who:\nHas hands-on experience shipping changes to the Nubank app.\n\nCan evaluate the impact of app changes, safeguarding latency, reliability, and customer experience against regressions.\n\nOperates at multiple altitudes - writing code, shaping technical direction, and aligning with stakeholders.\n\nThrives in high-ambiguity environments, takes strong ownership end-to-end, and has a clear bias for action.\n\nRaises the bar of the team - through mentoring, technical leadership, and proactive collaboration.\n\nBonus: has integrated third-party SDKs into the Nubank app.\n\nBonus: can also operate on the backend side, e.g., building services to collect data from the app and store it in the ETL.\n\nWhat we offer\nOpportunity to work on 0 to 1 projects with M-Team visibility.\n\nOpportunity to contribute to projects that have direct and outsized impact on PNL.\n\nHigh-impact problems with real product reach, helping shape AI-native experiences inside the Nubank app.\n\nA senior, high-caliber environment with close partnership across product, platform, and AI teams.\n\nPlenty of ownership and room to shape the path forward in a space that is still being defined.\n\nThe chance to build with ambition and speed, while helping create the foundations that let AI products, models, and flows scale across Nubank.\n\nContact\nHelder Dias→ Slack: @helderdias\n\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.
