Job Summary

The Principal Threat Intelligence Hunter will sit within Unit 42 Managed Threat Hunting and drive proactive, intelligence-led hunting across customer environments.

This role combines hands-on threat hunting with cyber threat intelligence analysis, helping multinational organizations stay one step ahead of adversaries and cyber threats.

The Principal Cyber Threat Intelligence Hunter will analyze public and private threat intelligence, track adversary activity & capabilities, engage in rapid response efforts, model frontline incident data, then translate that intelligence into actionable hunting hypotheses, investigation workflows, behavioural profiles, and ultimately targeted customer notifications designed to empower our customers’ response and disrupt adversary activity.

This role will work across customer telemetry to investigate suspicious activity, validate emerging threats, and contribute to timely, professional reporting. The role will also collaborate closely with threat hunters, detection engineers, incident responders, MDR teams, and Unit 42 intelligence and security researchers to operationalize intelligence quickly and improve hunting outcomes across the service.

Ultimately, this is a proactive, research-driven hunting role for an expert who can connect intelligence with real-world telemetry, maintain ongoing threat tracking while responding to emerging threats, fingerprint attacker behavior, investigate security incidents, mentor peers, and clearly communicate findings.
