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.

About the role
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.
• Drive Cross‑Unit Collaboration & Alignment: Ensure architectural alignment and smart reuse across Lending, Credit Card, and Credit Platform (Core Banking), avoiding duplicated flows and inconsistent debt behaviors.
• 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!
