• Establishing a service catalog with clearly defined SLAs and OLAs aligned with internal stakeholder expectations.
• Owning the end-to-end ITSM toolchain (Jira Service Management or equivalent): configuration, workflow design, form logic, SLA rules, and integrations with adjacent systems.
• Identifying and closing automation gaps — routing, escalation, notifications, and reporting — partnering with engineering teams to reduce manual toil across operations.
• Defining and tracking operational KPIs (MTTR, SLA compliance, first-contact resolution, change success rate) and building regular reporting cadences for leadership and stakeholders.
• Establishing a Change Advisory Board (CAB) with structured documentation and approval workflows.
• Supporting audit and compliance requirements with structured evidence of IT operational controls, essential in a regulated financial environment.
• Driving ITSM adoption across the organization, creating runbooks, training materials, and documentation that embed service management culture at scale.

We Are Looking For a Person Who Has

Mandatory qualifications

• 7+ years of experience in IT service management, IT operations, or a related discipline.
• Deep ITIL v4 expertise; ITIL 4 Foundation or Managing Professional certification strongly preferred.
• Proven track record of building ITSM practices from scratch or significantly transforming an existing function.
• Hands-on experience owning and configuring ITSM tooling end-to-end (Jira Service Management, ServiceNow, or equivalent) — not just using it, but designing it.
• Ability to work cross-functionally in a fast-paced, engineering-led environment, with strong influence-without-authority skills.
• Strong written and verbal communication, including the ability to present to senior leadership.

Nice-to-have qualifications

Opportunity

We are hiring a Senior Staff or Principal Engineer to support driving the technical vision and execution for Nubank’s Digital Ecosystem division, with initial focus on NuPay, Ads & Rewards and Insurance. This is a division‑level leadership role: you will work with exceptional engineers (including staff engineers), lead cross‑org architectural decisions, negotiate trade‑offs with product/finance/legal, and enable scalable delivery of high‑impact products (checkout & wallet, advertiser platform and benefits hub, and 1‑click insurance products).

2026's vision and (how this role contributes) 

In 2026 we will transform the Digital Ecosystem into a place where customers discover advantages, pay effortlessly and feel protected, and where merchants grow through data‑driven integrated partnerships. Our priorities are: (1) elevating app quality, (2) deepening customer engagement with contextual and personalized experiences, (3) making Nubank the preferred payments partner and growth engine for merchants, and (4) ensuring scalable, compliant, and financially healthy foundations. This role will own the technical plan to deliver that vision across NuPay, Ads & Rewards and Insurance.

Mission design and operationalize the 2–3 year technical end‑state for the Digital Ecosystem so that:

• NuPay scales to become the de facto checkout and wallet for Nubank customers (TPV ×2 by Dec/26; wallet >3M MAU),
• Ads & Rewards delivers the Advantages Tab, a performant advertiser platform and Ads POC with merchants, and drives material ecosystem revenue,
• Insurance launches and scales high‑quality one‑click complements (Mobile Insurance Relaunch, Pix Protegido evolution), while maintaining aggressive SLOs, strong observability, controlled TCO and an elevated engineering culture.

Core responsibilities

• Support defining the division’s technical end‑state (2–3 years): architecture, shard/partition strategy, migration path (one‑stack) and explicit trade‑offs (cost × latency × availability).
• Co-own availability and performance: set SLIs/SLOs, error budgets, runbooks, incident playbooks and an observability strategy that supports merchants with strict SLAs.
• Support Ads & Rewards platform design: advertiser platform (audience & campaign management), decision/bidding service, real‑time vs batch decisioning, measurement & attribution (ROAS/incrementality), and minimise impact on app UX.
• Drive NuPay ↔ Ads integration for aspirational purchases: real‑time underwriting, multi‑source funding, take‑rate modelling, card‑on‑file / wallet flows and onboarding for flagship merchants.
• Enable Insurance delivery: technical enablement for one‑click products, partner integration and governance (e.g., Chubb), migration to subscription/billing platform where applicable, and app quality improvements (TTFD, dashboards, NPS).
• Support one‑stack discovery and phased migration: balance platformization with pragmatic delivery and tech‑debt management to avoid blocking growth.
• Catalyse product quality culture: introduce and operationalize Product Quality Reviews, drive app excellence rituals, and ensure UX/technical quality are considered across the product lifecycle.
• Mentor and grow engineering leaders and staff engineers; run RFCs, tech talks and post‑mortems; design career paths and enable managers to deliver cross‑BU initiatives.
• Represent the division in cross‑org negotiations and external partner discussions (merchants, partners, regulators), aligning stakeholders and escalating risks proactively.
• Track and report technical impact against business metrics and engineering health indicators.

Key business & engineering metrics you will influence

• NuPay: TPV growth (2× by Dec/26), wallet MAU (>3M), share‑of‑checkout (SoC), p99 latency and availability for merchant traffic.
• Ads & Rewards: ad revenue targets (material ecosystem revenue), ROAS / iROAS / incrementality, CTR, Ads POC results (≥2 merchants), Advantages Tab / Shelves Platform launch.
• Insurance: one‑click complements GWP target (R$493M EOY), product NPS (>60 targets), churn reduction via billing/tolerance changes.
• Engineering health: Engineering Stability Index (ESI), App Quality Score, incident frequency/severity, time to integrate new partners.

Challenges and opportunities (what you’ll own)

• World‑class app quality & Magic App MVP: raise engineering and product expectations, and deliver first‑layer Magic App experiences (Advantages Tab, widgets, contextual flows such as AIPB).
• Real‑time decisioning and aspirational financing: enable low‑latency ads decisioning and NuPay real‑time underwriting for extended financing while preserving app performance.
• One‑click Insurance at scale: deliver MIR (no IMEI) and Pix Protegido evolution, dedicating energy to one‑click complements and partnering with Chubb while retaining monitoring/control.
• Capture offline transactions: accelerate NuPay NFC wallet adoption as an offensive play to reach ~3M MAU and increase offline SoC.
• Platform & compliance foundations: complete SPB integration, advance One‑Stack Project, meet Magic App and regulatory mandates, and ensure resilient, cost‑effective infra.

What you’ll find in the team

• High‑calibre engineers, including staff engineers and experienced engineering managers.
• Complex, high‑impact problems at scale: large merchant integrations, real‑time decisioning, strict SLOs and multi‑partner dependencies.
• Autonomy to shape architecture, product quality rituals and the division roadmap, plus the responsibility to align delivery across product, infra, legal and commercial stakeholders.

What you’ll navigate

• Heavy cross‑BU dependencies (Global Platforms, Nubank+, UV, Marketing) requiring strong stakeholder orchestration.
• Regulatory changes (SPB/BCB) that may force re‑architecture or open‑scheme decisions.
• Dependence on third‑party vendors (wallet SDKs, insurance partners) and partner infra limitations.
• Balancing rapid commercialization and monetization with fraud/credit loss control and sustainable unit economics.
• Trade‑offs between accelerating one‑stack migration and accepting short‑term technical debt to preserve delivery velocity.

We are hiring a Senior Staff Software Engineer to help lead the architectural direction of Nubank’s Global Debt Resolution platform, operating horizontally across all business areas. You will align the debt resolution stack to a cohesive long-term technical vision spanning Lending, Credit Card, and Credit Platform (Core Banking), ensuring we build globally scalable, compliant, and reusable solutions. This is a high‑influence IC leadership role where you will shape both the platform and the teams that build on top of it.

You will identify the right long‑term patterns for collections, renegotiations, and payments, and push them consistently across all business areas and credit domains. By sitting at the intersection of Lending, Credit Card, and Credit Platform, you will ensure every new initiative builds toward a unified, multi‑market debt resolution platform.

Mission
Design and operationalize a horizontal technical strategy for Global Debt Resolution so that:

• Legacy vs. Future is Deliberate: The boundaries between legacy, stable, and future systems are explicit, with clear migration plans and guardrails that reduce long‑term complexity and risk.
• Cross‑BU Leverage is Maximized: High‑leverage capabilities (e.g., renegotiation, late‑state flows, payment allocation, credit core integrations) are built once and reused across Debt Resolution, Lending, Credit Card, and Core Banking, instead of re‑implemented in silos.
• Business & Tech are Seamlessly Aligned: You act as a direct technical partner to business area leads and GMs, turning ambiguous credit/debt constraints into clear platform strategies and delivery roadmaps.

Core Responsibilities

• Lead Architectural Direction for Global Debt Resolution: Define and evolve the long‑term architecture for the Debt Resolution platform.

• Design for Multi‑Market Scalability: Architect and evolve foundational systems to support multi‑geo rollouts, minimizing per‑country forks and enabling configuration‑driven behavior instead of code‑driven divergence.
• Mentor Senior Engineers & Managers: Act as a technical mentor and challenger ICs and engineering managers in the BU, raising the bar on architectural depth, system thinking, and cross‑domain collaboration.
• Balance Five‑Year Vision with Near‑Term Delivery: Combine long‑term architectural thinking with hands‑on support for current roadmaps in all business areas, ensuring that short‑term delivery steps move us closer to the desired target architecture.

Key Business & Engineering Metrics You Will Influence

• Recovery Efficiency & Economics
• Improved collections and renegotiation efficiency through better tooling and shared capabilities.
• Reduced cost‑to‑serve per renegotiation or resolution flow.
• Platform Reuse & Adoption
• Increased reuse of shared Debt Resolution components across products and geos.
• Higher adoption rate of common patterns and building blocks versus bespoke solutions.
• Engineering Stability & Correctness
• Fewer incidents and production issues related to debt resolution, late‑state flows, or payment allocation.
• Reduced regression and rework when launching new markets or features.
• Time‑to‑Market & Migration Progress
• Faster launch of new markets and debt strategies on top of shared platforms.
• Clear progress on deprecating legacy systems and moving flows into the target architecture.
• Stakeholder Alignment & Satisfaction
• Stronger perception of engineering as a strategic partner by GMs and business leaders.
• Improved clarity of ownership and roadmaps across teams touching Debt Resolution.

Challenges and Opportunities (What You’ll Own)

• Unifying Architectures: You will tackle the challenge of multiple, partially overlapping debt resolution stacks by identifying common patterns and driving convergence toward a single, extensible platform.
• Making the Best Solution the Default Solution: You will ensure that the best ideas from any one team become the default standard for all, through clear patterns, documentation, and hands‑on collaboration.
• Operating with High Agency: You will have the mandate to push for global efficiency and correctness, while working through influence—bringing along Staff+ engineers, EMs, and PMs across multiple BUs.
• Balancing Risk, Compliance, and Speed: You will continually reconcile regulatory constraints, credit risk needs, and product velocity, making trade‑offs explicit and sustainable in the architecture.

What You’ll Navigate

• Complexity of Scale & Legacy: Balancing immediate needs of specific product areas with the long‑term goal of a unified, multi‑market Debt Resolution platform, including leading teams through multi‑year migrations.
• Constant Context & Communication Switching: Moving fluidly between deep technical design reviews and RFCs with engineers, and high‑level strategy discussions with GMs, Product Directors, Risk, and Operations.
• Cross‑Geo & Cross‑BU Collaboration: Working with teams across geographies, and across multiple business units, requiring strong remote collaboration, clarity in documentation, and cultural adaptability.

If you feel interested in these challenges and want to work on a highly engaged and talented team transforming how Debt works in Brazil and beyond, this is the place for you!

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.

If you feel interested in these challenges and want to work on a highly engaged and talented team transforming how investments work in Brazil and beyond, this is the place for you!

Principal Engineer, Mobile Platforms

The Opportunity:

This position is for an Engineer Principal (IC9) to join the Mobile Platforms BU.

Mobile Platforms is the BU responsible for Nubank’s entire mobile foundation: we design, build, and operate the platforms that power the Nubank app across all markets. The BU is organized in three business areas – App Foundations (core architecture, app startup, developer experience), App Enablement (navigation performance, Backend Driven Content/BDC, design system infra & Rosetta), and App Release (CI/CD, release train, observability, app analytics & data). Together, these areas provide the canonical Flutter + BDC architecture, tooling, and guardrails that enable product teams to ship a fast, reliable, and consistent app at global scale.

About Nubank's Engineering Culture:

We believe in small, independent teams, a process-light environment, and a culture of trust and collaboration. We made a strategic bet on Flutter and Server-Driven UI not just for technical reasons, but because they empower our engineers to work end-to-end and scale our organization. You will be a key steward and champion of this culture, driving technical decisions that reinforce our principles of autonomy and developer empowerment.  

What we have to offer:

• The opportunity to lead the technical direction of Nubank’s Mobile Platform – the foundational system that underpins the Nubank app for tens of millions of customers across all markets.
• Ownership of multi‑year, high‑visibility initiatives such as Mobile Destination Architecture, native code deprecation, app startup refactor, navigation performance, BDC evolution and App Excellence, with clear impact on company OKRs.
• A uniquely cross‑cutting scope across App Foundations, App Enablement and App Release – spanning architecture, developer experience, CI/CD, observability and data – allowing you to shape how the entire engineering org builds mobile products.
• Space to grow your principal‑level leadership: driving strategy, defining technical roadmaps, sponsoring other senior/principal engineers, and representing Mobile Platforms in cross‑company forums and executive discussions.
• A highly collaborative environment with top mobile, platform and experience design talent, where you will partner closely with Magic App, NuDS, Growth and markets teams to deliver a world‑class, consistent and high‑performance app.

Core Qualifications (What We're Looking For)

• 15+ years of software engineering experience, with a proven track record of designing, building, and operating large-scale mobile applications or platforms at an enterprise level.
• Has deep expertise in mobile architecture (Flutter/Dart, native bridges, modularization, mono-repo architectures) and can design end‑to‑end solutions spanning app startup, navigation, state management, and release lifecycle.
• Understands and can evolve BDC (Backend Driven Content) as Nubank’s main server‑driven UI platform, defining how BDC, Flutter and NuDS work together to enable safe, fast iteration without depending on store releases.
• Is capable of setting the technical vision for the three Mobile Platforms business areas (App Foundations, App Enablement, App Release), connecting architecture choices with company‑level goals such as App Excellence, Magic App and Destination Architecture.
• Has a strong track record of leading large, ambiguous cross‑org initiatives – e.g., native‑to‑Flutter/BDC migrations, app startup refactors, navigation performance programs, or observability/analytics redesigns – influencing dozens of squads and multiple BUs.
• Drives platform engineering at scale: defines canonical patterns, RFCs and reference implementations; creates reusable tools/libraries; and ensures that internal customers can adopt the platform with low friction and high quality.
• Is comfortable leading through influence: aligning PMs, EMs, Staff/Principal engineers and leadership on trade‑offs (performance vs. flexibility, platform vs. product), and making tough calls grounded in data, risk and long‑term sustainability.
• Invests heavily in technical leadership and mentorship, raising the bar for senior engineers across Mobile Platforms and product BUs, and building a strong culture around architecture reviews, design docs, and post‑incident learning.
• Cares deeply about observability, reliability and release health for mobile: tying together app metrics (startup, TTFD, crashes, jank), CI/CD, feature rollout (BDC + app releases) and on‑call practices into a coherent strategy.
• Is motivated by working on a horizontal, high‑impact platform that directly shapes how every experience in the Nubank app is built, released and monitored, across Brazil, Mexico, Colombia and future markets.

If you feel interested in these challenges and want to work on a very engaged and talented team, this is the place for you!

Opportunity

We are hiring a Principal Engineer to drive architectural consistency and technical excellence for Nubank’s Global Credit Card division—our largest business unit. You will operate across core platforms and product areas to ensure we are building globally optimal solutions. This is a high-influence leadership role where you will align technical strategy with business General Managers to maximize the impact of our platform investments.

2026's Vision (and how this role contributes)

In 2026, the Credit Card division will focus on maturing our core platform to support massive scale while maintaining rapid product innovation. This role is the "downward force" that identifies efficient architectural patterns and pushes them across the organization. By sitting across multiple business areas, you will prevent technical silos and ensure that every engineering investment reinforces a unified, scalable global architecture.

Mission

Design and operationalize a horizontal technical strategy for the Credit Card division so that:
