About the role
The Blockchain Security team sits within the Product Security & Assurance BA, part of the Information Technology and Security (ITSec) BU. Our mission is to support the security of Nu's crypto operation. In the context of Nu's global expansion, keeping these products secure, and demonstrably compliant with financial regulators, is a direct condition for our ability to operate and grow.
As a Senior Security Engineer on this team, you own the security posture of our crypto operation. You are the person who thinks like an attacker so our products can withstand real ones: finding vulnerabilities before adversaries do, embedding product security into how crypto products are designed and built, and making sure our controls satisfy both internal risk standards and external regulatory requirements. You won't just run security tools. You'll build and operate the ones that protect our crypto products, from hardened ingress and monitoring/alerting systems to secure secret-management and automated security-review tooling. Your work directly protects customer funds and Nu's ability to run crypto products at scale.
