Cybersecurity Expert

About this role

**Role Overview** - Mercor is seeking senior cybersecurity professionals to build evaluation tasks for AI systems operating in security operations, incident response, and risk management contexts. - The workflows are calibrated to the threat sophistication, business risk stakes, and scope of major enterprise security programs. - This role builds worlds on two tracks: a US track (NIST Cybersecurity Framework, SOC 2) and an International track (ISO 27001, EU NIS2 Directive). Experts qualified in either or both tracks are encouraged to apply. - Contributors design cybersecurity scenarios, draft reference outputs, and write rubrics that capture how senior security leaders think. **Key Responsibilities** - Construct cybersecurity scenarios spanning security operations center monitoring, incident response and forensics, vulnerability management, and security architecture design. - Build tasks across security operations and threat detection, incident response and digital forensics, vulnerability and penetration testing, security architecture and engineering, and governance/risk/compliance. - Develop scenarios involving tools such as SIEM platforms (Splunk, Microsoft Sentinel), EDR tools (CrowdStrike), vulnerability scanners (Tenable, Qualys), and GRC platforms used at major enterprises. - Apply cybersecurity methodologies (threat modeling, incident response playbooks, risk assessment) to the standards track a world targets (US: NIST CSF, SOC 2; International: ISO 27001, NIS2), and produce reference incident reports, security assessments, architecture designs, and compliance documentation. - Author rubrics that distinguish authentic security judgment from generic textbook or certification-exam-level recall. **Ideal Qualifications** - 5+ years working as a security engineer or CISO at a major company or security firm (Mandiant, CrowdStrike, or an in-house CISO/security lead). - Direct ownership of incident response programs, security architecture, or compliance initiatives. - Fluency in security tooling, plus understanding of regulatory frameworks and the current threat landscape. - A recognized professional credential is strongly preferred (CISSP, CISM, or an international equivalent); prior rubric or training authorship is a plus.
