Job Summary

Mercor is recruiting on behalf of a cutting-edge AI research lab building advanced AI systems for cybersecurity applications. We are seeking senior cybersecurity professionals with deep hands-on experience across both defensive (Blue Team) and offensive (Red Team) security this role you will apply real-world adversarial and defensive expertise to evaluate stress-test and improve AI models designed to assist with threat detection incident response and attack simulation. Your insights will directly inform how AI systems reason about attacks evasions detection logic and response workflows. This is a flexible remote engagement ideal for experienced practitioners who have operated in enterprise consulting or high-security environments.

Key Responsibilities

Defensive (Blue Team) Contributions

Investigate and analyse real or simulated security incidents (e.g. phishing lateral movement ransomware privilege escalation).
Review logs and telemetry from SIEM EDR/XDR firewall cloud and identity systems.
Apply frameworks such as MITRE ATTACK to classify adversary behavior.
Evaluate alert quality detection rules triage decisions and response workflows.
Assess AI-generated investigations for technical correctness and operational realism.

Offensive (Red Team) Contributions

Analyse attack chains including initial access persistence privilege escalation lateral movement and data exfiltration.
Simulate adversarial thinking to evaluate detection gaps and bypass techniques.
Review exploit techniques payload behaviors and evasion strategies.
Provide insights into attack surface analysis and real-world adversary tactics.
Stress-test AI systems against realistic red-team scenarios.

AI Evaluation & Feedback

Provide structured reasoning explaining investigative and adversarial decisions.
Identify weaknesses in AI threat analysis and suggest improvements.
Help refine benchmarks for detection triage and attack simulation accuracy.

Requirements

Experience

5 years in cybersecurity with experience in one or more of:
- SOC Analyst (Level II/III)
