Guided by our mission to fight complexity and empower people, we are redefining financial services in Latin America and this is still just the beginning of the purple future we're building.

Listed on the New York Stock Exchange (NYSE: NU), we combine proprietary technology, data intelligence, and an efficient operating model to deliver financial products that are simple, accessible, and human.

Our impact has been recognized by global rankings such as Time 100 Companies, Fast Company’s Most Innovative Companies, and Forbes World’s Best Bank. Visit our institutional page https://international.nubank.com.br/careers/  

About the Role

We are looking for an experienced engineer who thrives on solving "meta-problems"—fixing the tools and processes that other teams rely on. You will be responsible for designing and implementing high-leverage automation, managing enterprise tool rollouts (e.g., Postman, n8n), and defining the technical governance for our next-generation AI workflows.

Key Responsibilities

• Enterprise Automation & Platform Engineering:
  • Lead the implementation and maintenance of automation platforms (e.g., n8n) to orchestrate workflows across business units.
  • Design and optimize critical communication infrastructure (e.g., AWS SES, email delivery resilience) to ensure high availability for internal and transactional messaging.
• AI & "Vibe Coding" Governance:
  • Drive the technical strategy for AI adoption within engineering workflows.
  • Develop governance frameworks to ensure safe, compliant, and effective use of AI coding assistants and agents.
  • Build "Minimum Control Platforms" that balance developer freedom with security and operational risk requirements.
• Internal Tooling Standards:
  • Define and enforce usage standards for developer tools (e.g., Postman for API lifecycle), ensuring consistency across squads.
  • Conduct "Discovery Design" for new internal products, ensuring they are inclusive and scalable across different technical frameworks.
• Cross-Functional Technical Leadership:
  • Act as a technical reference for the domain, influencing architectural decisions beyond the immediate team. Mentor senior engineers and partner with stakeholders (ITSec, Privacy) to align technical solutions with company policies.

What are we looking for?

Technical Skills

• Solid Software Engineering Background: Proficiency in modern programming languages (Clojure, Java, or Python preferred) and distributed systems.

• Infrastructure & Cloud: Strong hands-on experience with AWS (specifically services like SES, Lambda, IAM) and Infrastructure-as-Code (Terraform/CloudFormation).

• Automation Mindset: Experience with workflow automation tools (n8n, Zapier, or custom orchestration engines) and API integration.

• AI/LLM Familiarity: Interest or experience in integrating LLMs/AI agents into developer workflows (e.g., Cursor, Copilot, internal AI agents).

• Advanced English

Behavioral & Strategic Skills

• Governance-Aware: You understand that "efficiency" must be balanced with "security." You can design systems that are safe by default without destroying developer velocity.
• Problem Solver: You are comfortable debugging opaque infrastructure issues (like email deliverability drops) one day and writing a strategic policy document the next.
• Multiplier: You enjoy documenting your work, creating "Golden Paths" for other engineers, and teaching others how to use the tools you build.

Our Benefits

• Chance of earning equity at Nubank
• Food/ Meal Card (Vale-Refeição and/or Vale Alimentação)
• Public Transportation Commuting Benefit (Vale-Transporte)
• NuCare – Psychological, Financial and Legal Assistance Program

About the Team

The People Analytics Technology Operations (PATO) team is redefining what People & Culture infrastructure looks like for a company operating at global scale with an AI-first mandate. We don't run HR software — we build the systems that make HR itself obsolete in its traditional form. Our work touches every Nubanker, every country, every moment of the employee lifecycle. We are the internal frontier lab for agentic people systems.

About the Role

Here is the core question this role exists to answer: if you were designing People & Culture infrastructure from scratch today — knowing that AI agents will run most operations, humans will audit rather than execute, and the channels and surfaces workers interact with don't fully exist yet — what would you build?

This isn't a rhetorical question. It's the actual brief.

The SaaS era of HR technology is being disrupted faster than most incumbents can adapt. Workday, SAP, ServiceNow — products built for a world of human workflows and form-based interfaces — are structurally ill-equipped for an agent-native operating model. The real competitive moat in this next era won't be features. It will be the depth of integration within a specific domain, and the quality of the data and reasoning layer that sits beneath it. We have the rare opportunity to build that solution — purpose-built for the People & Culture domain — inside one of the most technically ambitious companies in the world.

As Global People Data & Tech Director, you will lead the effort to design and build this from the ground up. You will define what the agentic HR stack looks like: the data models that make agents actually useful, the orchestration layer that lets them act with minimal human friction, the audit surfaces that let people stay in control without becoming bottlenecks, and the foundational platform that scales to 40+ markets without scaling the team that builds it. Agentic development practices aren't a side methodology here — they are how this organisation will operate. You build with agents, you build for agents, and your team stays lean precisely because of it.

This role isn't for someone who has deep experience with HR software. It's for someone who looks at HR software and sees an industry ripe to be rebuilt. You are a product and infrastructure thinker who happens to care deeply about the employee experience — and who has the technical depth and organisational leadership to translate that vision into production systems used by hundreds of thousands of people.

Key Responsibilities

Define the Agent-Native HR Stack

• Design the architecture for a People & Culture platform where agents are first-class citizens: capable of executing hiring, onboarding, payroll, compliance, and performance workflows with minimal human intervention.
• Define the human-in-the-loop model — which decisions require human review, through what interfaces, with what level of latency — so that oversight is meaningful rather than ceremonial.
• Identify and kill the workflows that should no longer exist at all.

Build the Data Foundation

• Architect the People data layer that will serve as the substrate for agent reasoning, predictive analytics, and LLM-powered insight generation for the next decade.
• Ensure the data model is jurisdiction-aware from day one — built to accommodate the legal, cultural, and operational variance of 40+ markets without requiring structural rework per country.
• Drive the transition from fragmented HR data silos to a unified, real-time, auditable data layer that agents and analysts can trust equally.

Build With and For Agents

• Apply agentic development practices to your own team's engineering process — using agents to write, test, review, and deploy code so that headcount does not scale linearly with product scope.
• Lead the development of real-time AI-powered employee experiences: intelligent copilots, proactive guidance systems, and autonomous support channels that resolve needs before they become tickets.
• Advance Nubank's application of large language models to unstructured People data — feedback, communications, performance narratives — turning qualitative signal into structured organisational insight.

Own the Platform Vision

• Define the comprehensive HR platform roadmap — what we build, what we integrate, and what we deliberately do not own — with a bias toward deep integration over broad coverage.
• Ensure the platform is designed for global scale from the start: multi-currency, multi-jurisdiction, multi-language, and operable across legal entities without per-country engineering investment.
• Bridge strategic vision with hands-on execution, staying close enough to the codebase and architecture to make credible decisions and earn the trust of your engineering team.

Lead the Organisation

• Build and lead a high-performing, deliberately lean team that punches well above its headcount because it builds and operates with agents.
• Develop senior technical leaders who can own domains end-to-end, reducing coordination overhead and enabling faster iteration.
• Foster a culture of intellectual honesty — one that questions inherited assumptions about how HR technology should work, and is willing to discard anything that doesn't hold up.

Qualifications & Skills

What We're Looking For

We are not looking for someone who has spent their career in HR technology. We are looking for someone who has built consequential software systems, who thinks seriously about agents and automation, and who is intellectually excited by the opportunity to apply that background to a domain that is fundamentally underbuilt.

Required

• 10+ years in software engineering and technology leadership, with demonstrated experience owning large-scale production systems from architecture through operation.
• Deep fluency in data architecture and data modelling — the ability to design canonical data structures that remain coherent as business complexity grows across jurisdictions and entity types.
• Hands-on experience building with or designing for agentic systems: familiarity with LLM-based reasoning, tool use, multi-agent orchestration, and the failure modes that come with autonomous execution.
• Experience leading platform or infrastructure products — systems used by other teams and applications, not just end users — with the taste and discipline that entails.
• Proven ability to scale impact without scaling headcount: through leverage, tooling, great architecture, and a culture that defaults to automation before process.
• Strong engineering management skills, including the ability to hire, develop, and retain senior technical talent and engineering leaders.

Valued

• Experience building products that operate across multiple legal jurisdictions — especially products where regulatory variance is a first-class design constraint, not an afterthought.
• Background in developer platforms, internal tooling, or B2B SaaS — contexts where you have thought carefully about API design, data contracts, and integration depth.
• Familiarity with the People & Culture domain — not as a practitioner, but as a product builder who has spent time understanding what HR teams actually do, where the friction lives, and what automation can and cannot replace.
• Experience operating within a high-growth technology company where ambiguity is the norm and the product surface changes faster than any roadmap.

Core Leadership Skills

• Business Acumen: Drives strategic alignment by reading market dynamics, spotting where incumbents are structurally vulnerable, and translating that into build-vs-integrate decisions with long-term leverage.
• Communication: Moves between technical depth and executive narrative fluently — able to defend architectural choices with an engineer and explain the same decision to a board.
• Agile Adaptability: Leads in conditions of genuine uncertainty, treating early product iterations as learning instruments and calibrating direction based on evidence rather than original conviction.

Senior Staff Engineer, Investments Platforms

The Opportunity:

This position is for an Senior Staff Software Engineer to join the Investments Business Unit.

Investments Platforms is responsible for the core platforms that model Nubank’s investments business: custody, offer, order management, accounts, settlement and related domains. These platforms are the long‑term home for our investments capabilities and the main path to move away from legacy Invest systems that still handle a large portion of critical flows today. Your mandate is to help design, evolve and execute this environment and comply with regulatory requirements.

About Nubank's Engineering Culture:

We believe in small, empowered teams, a process‑light environment and a culture of ownership, learning and collaboration. Our architecture is platform‑oriented: we build extensible, agnostic business platforms (e.g., payments, banking, investments) that can be reused across products, markets and asset classes. You will be expected to think in terms of platforms first, translating complex investment domains into clean boundaries, contracts and abstractions that product teams can safely build on.

Nubank is also on a company‑wide journey to become an AI‑first company. We expect our senior engineers to be hands‑on with AI tools in their own work, and to help define how AI is used safely and productively in engineering and in products.

What we have to offer:

• Own the technical direction of Investments Platforms – the systems that implement Nubank’s investments business model in software (custody, offer, orders, account, settlement and more) and power how we scale investments in Brazil and future markets.

• Lead the migration off legacy Invest systems: design and execute strategies to move critical flows into modern Nubank platforms, while we continue operating at scale and meeting regulatory commitments.

• Work on a disruptive investments architecture – rethinking how investments should be modeled and operated end‑to‑end, rather than just lifting and shifting existing broker or custodian patterns.

• Drive AI usage in a high‑impact domain: help define how we use AI in investments – both in the products we ship and in how we design, build and operate platforms.

• Collaborate across the platform ecosystem – working closely with other business and technical platforms such as Payments and Banking, and with product squads that consume Investments Platforms.

• Global scope with hybrid flexibility: roles are based in Brazil, in a hybrid‑first model (office presence during the week plus periodic on‑site collaboration with other locations).

Core Qualifications (What We're Looking For)

• 12+ years of software engineering experience, including 5+ years working on large‑scale platforms or core systems in highly available, transactional environments (finance, payments, core banking, trading, etc.).

• Proven track record building and operating business platforms that are extensible, multi‑tenant and domain‑agnostic – e.g., custody, payments, banking, risk or similar – with clear contracts for consuming teams.

• Experience leading strategic migrations from legacy to new architectures: co‑existence patterns, strangler approaches, staged rollouts and data migration strategies that keep systems up while flows move off legacy.

• Strong foundation in distributed systems and event‑driven architectures: domain modeling, consistency and resiliency strategies, backpressure, observability, SLIs/SLOs and incident learning loops.

• Demonstrated platform engineering leadership at scale: defining reference architectures and RFCs, building reusable libraries and tools, setting platform SLAs, and making adoption low‑friction and high‑quality for internal customers.

• Comfortable working as a horizontal leader across stakeholders: aligning GMs, PMs, EMs and Staff/Principals on trade‑offs between speed, risk, platform consistency and product goals.

• Deep experience mentoring and multiplying senior engineers – raising the bar on architecture, design reviews, documentation and post‑incident retrospectives.

• Investments expertise: hands‑on experience with investments platforms (brokerage, custody, order management, funds, fixed income, equities, settlement, risk) and understanding of the Brazilian capital markets landscape.

• Platform background: prior work on other platforms (payments, core banking, investments) that shows you can design high‑abstraction, agnostic, extensible platforms and translate complex domains into clean boundaries and APIs.

• AI fluency: you are already experimenting with AI in your engineering practice (design exploration, code generation/review, analysis, automation) and are excited to help Nubank push its AI‑first agenda in a pragmatic, safe way.

• Language: Portuguese fluency is important; English is a plus rather than a hard requirement. We are open to strong IC8 candidates who can ramp up their English over time, and will trade off language in favor of outstanding technical and leadership fit where it makes sense.

• Resilience and ownership mindset: you are energized by ambiguous, high‑stakes scenarios, keep a constructive and optimistic stance, and actively pull teams toward positive cultural change instead of getting stuck in pessimism or only in the micro level.
