Senior Threat Intelligence Researcher

As a Senior Threat Intelligence Researcher, you will be tasked with leading deep-dive investigations into both emerging and known threats, while maintaining a vigilant watch over malware developments to ensure defenses remain a step ahead of evolving attack methods. You will synthesize complex data into actionable intelligence and provide senior management with the clear briefings necessary to understand and mitigate potential risks. You will also develop refined hunting strategies to adapt to and anticipate shifts in threat actor tactics and techniques, and track adversary infrastructure to effectively counteract shifts in threat actor tradecraft through detail-oriented investigation.

What Will You Do?

Primary responsibilities include:

Synthesize complex data, from internal hunt findings to intelligence gathered from dark web forums, leak sites, and research repositories, into actionable threat briefings and risk assessments for security leadership and senior stakeholders.

Lead in-depth, hypothesis-driven threat hunts across internal networks, cloud environments, and endpoints to uncover sophisticated intrusions that evade traditional security controls.

Map threat actor footprints internally by pivoting through EDR telemetry.

Analyze adversary tactics, techniques, and procedures (TTPs) within the environment, identifying shifts in execution, persistence, and lateral movement.

Trace adversary infrastructure externally by pivoting through domain registrations, SSL certificates, and passive DNS.

What Skills and Knowledge Will You Bring?

Ideal candidates will have:

A background in threat research, threat intelligence or threat hunting.

Knowledge of the cyber threat landscape, including threat actors and their tactics, techniques, and procedures (TTPs).

Strong analytical skills, with the ability to identify patterns and trends in large datasets.

Knowledge of how our products operate internally and how to maximize their telemetry.

Strong knowledge of YARA to track new malware families, along with knowledge of validation best practices.

An understanding of software vulnerabilities and the ability to implement internal hunting strategies to track their exploitation across the estate.

Knowledge of MITRE ATT&CK, CISA KEV, EPSS, AMITT, and MISP Galaxy.

Knowledge of malware analysis tools and techniques, including static and dynamic analysis, sandboxing, and debugging.

Technical writing and content development skills.

A solid technical understanding of how EDR works is preferred.

Relevant certifications, such as Certified Malware Analyst (CMA), Certified Reverse Engineering Analyst (CREA), or GIAC Certified Malware Reverse Engineer (GREM), are preferred.
