ABOUT THE ROLE

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.

YOU’LL BE RESPONSIBLE FOR

  • Set the technical strategy and architecture for the AI Private Banker mobile experience.

  • Lead the design, implementation, launch, and operation of a new conversational consumer product across iOS and Android.

  • Partner closely with product and design to translate emerging AI capabilities into interactions that feel simple, useful, and trustworthy.

  • Define how the experience handles dynamic responses, latency, interruptions, errors, recovery, feedback, and customer control.

  • Build reusable UI components, interaction patterns, and mobile foundations that can support AI experiences across multiple Nubank teams.

  • Own production quality across performance, accessibility, testing, instrumentation, observability, release readiness, and post-launch health.

  • Drive alignment across mobile, backend, platform, and AI/ML teams to move complex initiatives from ambiguity to production.

  • Mentor senior engineers and raise the broader organization’s standards for mobile architecture, product quality, and customer-centered engineering.
