Visit our Institutional Page About the role This position is for a Staff Software Engineer to join the Travel Squad inside the High Income) BU . A few of the company’s most important priorities right now are winning the high-income segment and building differentiated travel experiences for our customers. Travel owns products like Nu Viagens, eSIM, International Account and Travel Tab , working closely with partners such as Hopper, Gigs and Wise to deliver end-to-end journeys our customers can trust. We are still in the early days of scaling these products, with a lot to build and learn in both acquisition (how customers discover and hire Travel products) and engagement (how we keep experiences reliable, fast and delightful across trips, currencies and channels). This is a cross-squad Staff role : you will own the target architecture for the Travel ecosystem , lead a challenging architecture evolution plan (e.g., from WebView to API-based native experiences), and act as an AI-first engineering leader for the squad. You’ll be responsible for Owning the target architecture for the Travel ecosystem , including Multi-Currency Account (MCA), Nu Viagens and eSIM, and how these products work together and integrate with key dependencies inside and outside Nu — creating a robust, flexible Travel architecture across all segments (Roxinho, Nubank+, Ultravioleta). Envisioning and leading a multi-year architecture evolution plan , planning and sequencing migrations between legacy and new partner platforms with different integration patterns (e.g., WebView → API), unlocking capabilities such as high-quality usability, fast iteration, cross-sell with other products, customer-facing AI experiences, and direct integration with top Travel players. Acting as a strong technical representative in cross-squad and cross-company forums , aligning on shared infrastructure, API definitions, long-term platform commitments and roadmap sequencing. Providing AI-first engineering leadership for Travel: evolving the squad’s canonical AI context, practices and tooling across chapters, and setting a high bar for how AI is used in architecture, development and operations. Leading co-creation of solutions with external partners including joint API design, integration patterns and operational models, while dealing with constraints such as partial data visibility, partner SLAs and regulatory issues. Navigating ambiguity and operational edge cases (cancellations, schedule changes, FX and cross-border issues, ops and regulatory constraints), helping the team structure work to systematically handle complexity and run experiments (e.g., improving UEM) in parallel. Influencing the whole value stream , not just downstream: collaborating with Product, Ops, Risk/Fraud, and partners to align business urgency, platform capacity, controls (fraud/AML) and revenue retention, and drive decisions to closure. Multiplying through the team , not only via personal delivery but also by mentoring ICs, fostering a strong engineering culture, writing RFCs and design docs, and turning strategic direction into artifacts teams can execute against independently. We are looking for a person who has Required Solid experience as a Software Engineer , with a strong track record designing and evolving complex, distributed backends and platform architectures. Proven ability to own and drive target architectures across multiple products/squads, including planning and executing large-scale migrations (e.g., legacy → new partners, WebView → native/API). Strong background in integrations and platform engineering , ideally in domains such as travel, e-commerce, marketplaces, or other multi-partner ecosystems. Ability to navigate high ambiguity and complexity , especially in contexts with external partners, operational edge cases and regulatory/ops constraints. Demonstrated technical leadership in multi-stakeholder environments: aligning product urgency with platform capacity, balancing controls (e.g., fraud/AML) with revenue retention, and driving decisions to closure. Excellent communication and inclusive decision-making skills: you bring options and trade-offs, discuss using clear criteria, balance consensus vs. speed, and then help the team move forward with focus. Experience mentoring and multiplying other engineers , raising the tech bar, and converting strategic/architectural direction into concrete artifacts (RFCs, design docs, guidelines). AI-first mindset , with practical experience using AI tools in engineering workflows and appetite to lead the squad’s AI adoption (e.g., ADLC practices, canonical contexts, harnesses). Fluency in English (written and spoken) and residence in Brazil , with strong communication skills for daily interaction with global partners and cross-functional teams. Nice to have Previous experience in travel / OTA / hospitality / airlines or adjacent industries (nice to have but not mandatory). Experience integrating with third-party providers in complex, high-reliability customer journeys. Background in high-income / affluent customer products or premium experiences.
