Senior Global Security Investigator

About the Role

We are seeking a senior Global Security Investigator with a technical background to lead complex, long-running security investigations involving a full spectrum of threats - whether originating from internal employees, external threat actors, or supply chain partners. This role is about seeing the full chessboard and independently driving complex, multi-month cases across cyber, physical, and human domains.

In this role you will

• Independently conduct comprehensive security investigations from initial detection to resolution, including cases involving insiders, external actors, and supply chain and third-party risks.
• Lead proactive, data-driven threat-hunting efforts that weave together disparate signals to surface undetected insider or external threats before they escalate into incidents.
• Perform comprehensive technical analysis of complex hardware, software, and supplier supply chains to identify, enumerate, and mitigate risks.
• Partner closely with cross-functional teams, including Human Resources, Legal, Security, and IT, and external stakeholders or law enforcement when necessary.
• Collaborate with technical counterparts to enhance detections, resolve telemetry gaps, and implement new capabilities to identify security issues involving cyber, physical, and human domains.
• Collect, preserve, and analyze evidence from a variety of sources, including log data, digital forensics, subject interviews, access records, threat intelligence, and open-source intelligence (OSINT), to support investigative findings.
• Continuously improve investigative procedures and security controls based on investigations and lessons learned.

You might thrive in this role if you have

• Bachelor’s degree in Criminal Justice, Cybersecurity, or a related field (or equivalent experience) and 8+ years of investigative experience in counterintelligence, insider risk, forensic investigations, cybersecurity, supply chain security, or related domains.
• Unimpeachable integrity, sound judgment, and the ability to handle confidential matters with discretion.
• An active US security clearance, or willingness and eligibility to obtain one.
• Deep specialization in geopolitical threat domains, with hands-on experience identifying, assessing, and mitigating adversarial risks through tailored countermeasures.
• Expert knowledge of common security tooling, including EDR, DLP, UEBA, SIEM, SOAR and other related platforms.
• Demonstrated ability to independently write complex queries, automate data workflows, and analyze structured datasets.
• Excellent written and verbal communication skills, including the ability to distill complex findings into clear, actionable reports and explain technical issues to non-technical stakeholders.
• Exceptional collaboration skills with the ability to work across diverse teams (HR, Legal, IT, etc.) to lead projects and investigations with minimal guidance.
