## About the role

Nu is building secure, compliant crypto infrastructure that will expand financial access for millions of people across Latin America. As part of that effort, we're bringing personalized, data-driven crypto experiences to our customers through an internal conversational AI platform which is powered by their portfolio, risk appetite, market conditions, and financial behavior.

## What they're looking for

- Experience building data pipelines and integration layers that connect backend/product data to AI-driven systems (context engineering, tool/function calling) — collaborating with ML engineers rather than owning model training
- Solid understanding of blockchain concepts and crypto products (wallets, portfolios, transactions, on-chain data), with the ability to integrate deeply with protocols and core crypto infrastructure
- Experience working with customer data and behavior to drive personalization (segmentation, risk profiling, usage patterns)
- Strong distributed-systems fundamentals — experience designing and operating data pipelines and services at scale (throughput, consistency, failure handling, freshness, reliability), rather than expertise tied to a specific programming language
- Comfort working as a cross-team interface — translating a platform team's integration needs into clear data contracts and APIs
- Awareness of the risks of exposing financial data to LLM-driven surfaces (data integrity, injection risks, appropriate guardrails)
