## About the role

You will protect ZKsync's core: smart contracts, ZK circuits, and blockchain nodes. Your reviews, threat models, and incident work decide whether vulnerabilities are found by us or by attackers. The role owns internal security reviews of critical components, threat modeling, adversary research, and the security side of incident response, and it carries broad license to spot gaps and fix them beyond any assigned list.
