What Is a Blockchain Security Engineer?

Security engineers at crypto companies protect systems that hold value and are attacked constantly: key management and custody, infrastructure and application security, incident response, and — at protocol teams — the security of the on-chain code itself, overlapping with auditing. It is one of the industry's most consequential roles because failures are public and irreversible.
