About The Position

The Global Lending Foundations team, within our Global Lending BU, is building the platform that fundamentally changes how we design, build, and roll out lending decisions across new geographies. Our mission is to create the tools and evolve the architecture that make it dramatically easier to launch lending products in new countries, with high business impact and direct exposure to Nu’s global expansion. As a Staff Software Engineer – Lending Foundations, you will be a senior technical leader in this platform layer: defining the long-horizon technical direction for how Lending platforms scale across countries, products, and partners, and shaping how every future lending product is built across Brazil, the US, Mexico, Colombia and future markets. You will operate at platform scale — building shared infrastructure that other teams depend on for years — while working in a highly engaged, multi-level engineering group (IC7–IC4) and partnering closely with product and business leaders.

Requirements

Extensive experience as a senior / staff-level engineer designing and evolving complex distributed systems or platform layers that serve multiple product teams.
Deep experience with event-oriented architectures (e.g., CQRS, event sourcing, streaming) and clear views on the trade-offs of building shared infrastructure that other teams will depend on for years.
Strong background in at least one functional or JVM-based stack;
Proven track record owning architectural vision for large domains or platforms, and bringing clarity and direction in spaces where requirements and constraints are evolving.
Demonstrated ability to drive alignment on hard architectural decisions across multiple squads and stakeholders, including senior engineers and technical leaders.
Experience acting as a platform-oriented engineer, where primary customers are other engineering and product teams, and your work directly shapes what they can ship and how fast.
Strong communication skills — able to articulate complex technical concepts to both technical and non-technical audiences, and to influence decisions at multiple levels.

Nice To Haves

Experience in lending, credit, or financial services platforms.
Experience working in multi-country or global product environments.
Prior responsibility for migration or re-platforming initiatives at scale.
Familiarity with technologies like Clojure, Datomic, Kafka or similar paradigms is a strong plus

Responsibilities

Owning the architectural vision for Lending Foundations: Define and evolve the platform architecture that underpins lending products across countries, products, and partners, making decisions that outlast individual cycles.
Designing and scaling shared platform capabilities: Build core services, decisioning primitives and integration patterns that multiple lending teams rely on, balancing flexibility with consistency and long-term maintainability.
Leading cross-team architectural initiatives: Drive alignment on hard technical choices across engineering squads and stakeholders, bringing clarity where the path forward is genuinely unclear and ensuring coherent evolution of the Lending platform layer.
Evolving event-oriented architectures: Apply and refine CQRS and event-driven patterns across the platform, making thoughtful trade-offs when building shared infrastructure that must work across geographies and regulatory contexts.
Partnering with product and business leadership: Work closely with the Global Lending BU to translate business goals and expansion plans into platform capabilities and roadmaps, ensuring high, measurable impact on global lending expansion.
Multiplying senior engineering talent: Mentor senior engineers, help them grow toward Staff level, and raise the engineering bar through design reviews, technical guidance, and clear written and verbal communication.
