Security Engineer

ABOUT THE ROLE You’ll work on security across a platform that processes large volumes of sensitive data, including AI training pipelines, expert payments, and enterprise integrations. This is a hands-on engineering role focused on building and improving the systems that keep Mercor secure. We use AI heavily in our own security work. You should be comfortable building alongside AI code-gen tools, using LLMs to accelerate threat analysis, and automating away the repetitive work that slows security teams down. If you're the kind of engineer who writes a script instead of filing a ticket, you'll fit in here. We're in-person five days a week at our San Francisco headquarters, with first Fridays remote. New York could be an option for the right candidate. WHAT YOU'LL BUILD: - Detection and response pipelines that catch real threats, not checkbox alerts - Security automation that replaces manual processes - if you're doing something twice, automate it - Infrastructure hardening acr
