Nubank Senior Staff Software Engineer at Nubank to lead architecture and development of the Money Boxes core platform. Responsible for scalable, high-throughput distributed systems supporting multi-country financial products.
Responsibilities
Money Boxes ("Caixinhas") is one of Nubank’s most strategic product innovations, transforming how millions of customers organize, save, and grow their money across Latin America. As Nubank expands into new geographies and financial verticals, we are looking for an exceptional Senior Staff Software Engineer to serve as the chief technical authority for our Money Boxes core platform.
Your Mission: scale an extensible, multi-tenant Money Boxes platform that abstracts complex investment assets, yield generation mechanisms, and regulatory ledgering into simple, bulletproof platform capabilities across multiple international markets.
What You Will Own & Build
Money Boxes Platform Architecture: Define and execute the multi-year technical vision for Money Boxes backend architecture, ensuring high extensibility to support diverse underlying assets (e.g., fixed income, yield-bearing accounts, money market funds) across different countries.
Core Ledgering & Transaction Engines: Architect high-throughput, double-entry accounting engines and balance tracking systems that guarantee exact-once delivery, deterministic reconciliation, and real-time calculation of accruals and yield.
Liquidity & Asset Routing Infrastructure: Design resilient execution flows for deposits, withdrawals, and auto-investments, managing real-time settlement with internal brokerages, clearinghouses, and banking rails with low latencies and zero transactional error margin.
Multi-Country & Multi-Currency Abstractions: Abstract regional regulatory rules, local tax logic, and currency nuances into clean platform boundaries so product squads can launch localized Money Boxes experiences in record time.
Technical RFC Leadership: Author comprehensive design documents (RFCs) and drive architectural consensus across Payments, Core Banking, Investments, and Security leadership.
Engineering Mentorship & Technical Rigor: Elevate engineering standards across Money Boxes squads by mentoring senior engineers in distributed systems design, resilience patterns, fault tolerance, and domain-driven design.
What We Are Looking For
Senior IC Track Record: Proven experience as a senior technical leader (Staff/Senior Staff level) designing, operating, and scaling highly available, mission-critical distributed systems.
Fintech, Banking, or Investments Domain Depth: Deep hands-on experience building systems in transactional environments—such as savings platforms, ledger/accounting engines, investment order management, custody, or core banking infrastructure.
