Senior Staff Engineer Investments Platforms

The Opportunity:

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

Investments Platforms is responsible for the core platforms that model Nubanks investments business: custody offer order management accounts settlement and related domains. These platforms are the longterm 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 Nubanks Engineering Culture:

We believe in small empowered teams a processlight environment and a culture of ownership learning and collaboration. Our architecture is platformoriented: 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 companywide journey to become an AIfirst company. We expect our senior engineers to be handson 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 Nubanks 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 endtoend rather than just lifting and shifting existing broker or custodian patterns.

• Drive AI usage in a highimpact 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 Brazilin a hybridfirst model (office presence during the week plus periodic onsite collaboration with other locations).

Core Qualifications (What Were Looking For)

• 12 years of software engineering experience including 5 years working on largescale 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 multitenant and domainagnostic e.g. custody payments banking risk or similar with clear contracts for consuming teams.

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

• Strong foundation in distributed systems and eventdriven 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 lowfriction and highquality for internal customers.

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

• Deep experience mentoring and multiplying senior engineers raising the bar on architecture design reviews documentation and postincident retrospectives.

• Investments expertise: handson 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 highabstraction 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 AIfirst 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 highstakes 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!
