Staff Software Engineer - Digital Experience Platform

The Digital Experience Platform (DXP) is Nubank’s AI-first platform ecosystem designed to radically compress our product development workflow from concept to production. Today, building “Magic App”-quality experiences in our Backend-Driven Content (BDC) stack takes ~49 working days and ~24 handoff-heavy steps — DXP exists to close this Creation Gap and Workflow Gap by making AI-native tooling the default way we design, build, and ship experiences. We are building four core products: DXP Studio (an AI-powered creation environment that turns Figma designs into production-ready BDC code), DXP Dictionary (the curated knowledge base that makes AI agents “Nu-aware”), DXP Spec Protocol (our vendor-agnostic abstraction layer), and DXP Workflow (an orchestration platform for hybrid human + AI agent teams across the product lifecycle). As a Staff Software Engineer – DXP, you will be the technical leader and multiplier for this initiative: shaping the architecture of an AI-native platform, driving critical decisions across the Figma-to-BDC pipeline and agent orchestration, and partnering closely with Product, Design, and Engineering leadership to prove value and scale the platform company-wide. We’re looking for someone genuinely addicted to AI — who obsessively explores new models, agent frameworks, and AI-powered tools, and can turn that passion into leverage for thousands of Nubank engineers.

Responsibilities

Architect the DXP Studio pipeline: Design and lead the end-to-end architecture for the Figma → DXP Spec → BDC code generation flow, ensuring vendor-agnostic abstractions (DXP Spec Protocol), NuDS component fidelity, and production-ready output quality.; Lead AI agent integration & orchestration: Define how AI agents (codegen, QA, design-mapping, etc.) are composed, executed, and supervised inside DXP; drive decisions on LLM provider abstraction, context-assembly strategies, MCP tool surfaces, and execution environments.; Own the DXP Dictionary and knowledge architecture: Architect the knowledge base that turns generic AI into Nubank-aware agents — how NuDS specs, tokens, canonical patterns and domain knowledge are ingested, structured, and consumed by generation and validation pipelines.; Drive cross-platform integration: Lead the technical integration model with NuDS (component catalog & tokens), BDC/Core (patterns & services), HPP (widget / homepage infrastructure), and App Excellence (observability & quality metrics), defining clear contracts that position DXP as an orchestrator on top of existing platforms.; Establish quality-at-generation-time: Design automated quality enforcement for generated experiences — NuDS compliance, token correctness, accessibility rules, structural integrity, golden tests — so governance happens by default at generation time, not via manual post-hoc review.; Set technical strategy and roadmap: Contribute to the 6–18 month technical strategy for DXP, translating strategic bets into executable plans, identifying architectural risks and trade-offs between POCs and long-term scalability.; Multiply engineering excellence: Mentor engineers within DXP and partner teams (NuDS, BDC, Mobile Platform), lead design reviews and RFCs, and raise the bar for AI-augmented development practices across Nubank.

Requirements

Genuine obsession with AI tools and workflows — deep, hands-on, daily experience with LLMs, AI agents and modern AI-powered dev tools (e.g., Claude Code, Cursor, Copilot, custom agents, MCP servers); you are the person who has tried new tools before others even ask about them.; Strong software architecture skills, with experience designing multi-component platform systems that integrate AI/LLM capabilities into production workflows.; Deep understanding of design-to-code pipelines, design systems or component-driven UI development, ideally bridging design tooling (e.g., Figma) and code generation.; Practical experience with AI/LLM integration in software products: prompt engineering, agent orchestration, context management, RAG architectures and/or MCP tool development.; Proven ability to lead cross-functional technical initiatives involving multiple teams and stakeholders, driving alignment and delivery in ambiguous environments.; Excellent communication skills, translating complex architectural decisions into clear narratives for Product, Design and senior leadership.; Product-minded mindset, balancing technical excellence with pragmatic delivery — comfortable proving value via POCs before scaling platform capabilities.; Experience with Nubank’s stack or similar patterns: BDC (Backend-Driven Content), and broader mobile/frontend ecosystems.

Nice to have

Experience with Flutter at the intersection of design systems and code generation.; Hands-on experience building or integrating AI coding agents (e.g., Claude Code, Devin, Cursor) into team workflows.; Familiarity with workflow orchestration platforms, agent farms or multi-agent systems.; Understanding of analytical architectures, experimentation platforms, feature flags and progressive rollout strategies for generated experiences.; Prior experience productizing internal developer tools or platforms that serve large engineering orgs.; Contributions to open-source AI developer tools or active presence in the AI-for-developers community.
