Senior Global Security Investigator at OpenAI · LumiJobs

Responsibilities

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.
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.
