About the role
As Nu scales its footprint globally, seamless international money movement is a cornerstone of our growth. We are looking for a Senior Staff Software Engineer to own the overarching architecture for Nu’s global Remittance and Cross-Border Payment Platforms. In this role, you will sit at the strategic intersection of high-scale distributed backend systems, foreign exchange (FX) engines, international payment rails, and global compliance platforms. You won't just maintain existing pipelines, you will architect the foundation that enables instant, low-cost, multi-currency money movement for millions of users across borders.Your mission: maintain and grow a resilient, multi-country remittance engine that abstracts away complex global payment rails and regulatory requirements into simple, reliable platform capabilities.
What You Will Own & Build
- Core Remittance Platform Architecture: Design and evolve the long-term technical vision for multi-currency money movement, FX rate locking, payout routing, and ledgering across international corridors.
- Global Rail Integration Strategy: Architect plug-and-play integrations with global payout partners, banking networks, and local clearing rails (e.g., PIX, SPEI, FedNow, SWIFT) with ultra-high reliability and low latencies.
- Resilient Ledgering & FX Management: Build transaction execution engines that guarantee exact-once delivery, deterministic ledger balancing, real-time liquidity management, and auditability under massive concurrency.
- Compliance & Risk System Abstractions: Partner with AML, KYC, Sanctions Screening, and Regulatory Engineering teams to embed real-time screening seamlessly into payment paths without degrading user experience or throughput.
- Technical RFC Leadership: Drive cross-organizational consensus on high-impact architectural decisions through detailed RFCs, design reviews, and technical documentation.
- Engineering Mentorship: Multiply organizational velocity by mentoring senior engineers across payments squads in distributed systems principles, resilience engineering, and payment domain knowledge.
What We Are Looking For
- Tenure in Backend Software Engineering: Proven track record of designing, operating, and scaling highly available, mission-critical backend distributed platforms in demanding environments (e.g., fintech, payments, banking, or cloud platform infrastructure).
