Nu is building the AI Private Banker, a flagship AI product designed to bring personalized financial guidance to customers directly inside the Nubank app. As a Staff Mobile Software Engineer, you will be a leading mobile technical voice for this product, shaping new conversational experiences from product definition through production and continuous evolution
Your scope will be the mobile experience as a whole, not a single feature or set of screens inside an established flow. You will set the mobile architecture and product-engineering direction, shape how these interactions behave inside the app, and make the tradeoffs required to move quickly without compromising performance, accessibility, reliability, or customer trust
Your impact will extend beyond the initial product experience. You will define reusable UI components, interaction patterns, and technical foundations that other teams can use to build consistent AI experiences across Nubank. You will partner closely with product, design, backend, platform, and AI/ML teams, mentor senior engineers, and remain hands-on and accountable for the experience in production
