CYE is looking for a Cyber Security Expert with hands-on experience in offensive security, possessing strong technical capabilities, in-depth knowledge of adversary simulation, and a passion for Red Team operations.

CYE is a cybersecurity firm specializing in advanced adversary simulation and offensive security testing. We deliver Red Team assessments for Fortune 500 companies, simulating sophisticated, real-world attacks across external, internal, cloud and Active Directory environments.
