Principal Security Engineer (Crypto / Digital Assets)

We are looking for a Principal Security Engineer with deep crypto domain expertise to lead security across our regulated digital-asset business. As we build out spot trading, custody, staking and on-chain services for our client base, security is the foundation the whole business stands on. This role owns it. You will be the security owner for our crypto platform's custody and on-chain layer end to end: architecture, engineering, operations and regulatory assurance for the parts of the stack that are unique to digital assets.

For platform capabilities already owned by central security teams (cloud, application security, IAM, SOC), you'll define the crypto-specific requirements and partner on delivery rather than duplicate ownership. You will work closely with risk, compliance, product and engineering, and report into the central security function.

This is a hands-on senior role for someone who understands that in digital-asset custody, a single key-management failure is a firm-ending event, and who builds controls accordingly.
