About the Role

At Nubank, we are entering a new chapter for our Investments business. We are moving away from traditional, siloed financial systems toward a global, scalable platform architecture that empowers millions of customers to grow their wealth. As a Staff Software Engineer, you will be a cornerstone of this transformation, ensuring our engineering culture and technical strategy can support the next decade of growth.

You will join the Investments Platforms team, where we build the core engines for custody, offers, and orders. Your mission is to "dehydrate" legacy systems by designing extensible, agnostic solutions that handle everything from fixed income to equities. This isn't just about writing code; it's about leading a cultural and technical revival, influencing your peers to adopt the best architectural practices while keeping the "plane flying" as we migrate critical flows.

Responsibilities

• Architect Scalable Platforms: Design and evolve core investment platforms (Custody, Orders, Offers) to be asset-agnostic and globally extensible.
• Drive Legacy Migration: Lead the construction of complex and innovative platforms to manage an Investments business in a scale unseen in the market.
• Technical Stewardship: Own the end-to-end technical lifecycle of high-impact projects, ensuring alignment with Nubank’s long-term business goals.
• Collaborate Cross-Functionally: Partner with Product, Design, and Operations to translate complex business requirements into elegant technical solutions.

Required Qualifications

• Platform Engineering Expertise: Proven track record of building and maintaining highly abstracted, extensible platforms (technical or business-focused) in a high-growth environment.
• Architecture at Scale: Deep experience designing distributed systems that handle high-concurrency and mission-critical financial flows.
• Resilient Leadership: Demonstrated ability to lead technical teams through periods of ambiguity, organizational change, or complex system migrations.

Nice to Have

• Investments Domain Knowledge: Prior experience with brokerage systems, asset classes (equities, fixed income), or financial regulatory environments.
• Cloud-Native Fluency: Deep familiarity with AWS or similar cloud providers and modern CI/CD practices.
• Pragmatic Problem Solving: Experience balancing the need for architectural purity with the necessity of delivering business value in a fast-paced setting.

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!
