About The Role
More about the Cybersecurity Labeling Expert role at Mercor
Cyberattacks cause billions in damages annually — ransomware cripples hospitals, data exfiltration exposes millions. As a Cybersecurity Labeling Expert, you'll be on the front lines of AI safety: reviewing real-world conversations flagged as potentially malicious and determining whether they represent genuine threats. Your judgments directly train the systems that keep AI out of the hands of bad actors.
What you'll do
Analyze Flagged AI Conversations — Ranging From Plain Text To Code-heavy Exchanges — And Apply Your Security Expertise To Assess Intent And Harm Across Four Domains
Why it matters
The difference between a security researcher and a threat actor often comes down to context, specificity, and intent — exactly what automated systems struggle to detect. Your ground-truth labels directly improve the classifiers that decide what AI will and won't help with.
What we're looking for

A Final Note: This is a role with Mercor not with Hatch.
