About the Role

OpenAI is seeking a senior Global Security Investigator with a technical background to lead complex, long-running security investigations involving threats originating from internal employees, external threat actors, or supply chain partners. The role involves independently driving complex, multi-month cases across cyber, physical, and human domains.

Responsibilities

• 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 combine disparate signals to identify 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 with Human Resources, Legal, Security, and IT teams, as well as external stakeholders and law enforcement when necessary.
• Collaborate with technical counterparts to enhance detections, resolve telemetry gaps, and implement capabilities for identifying security issues across cyber, physical, and human domains.
• Collect, preserve, and analyze evidence from 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.

Requirements

• Bachelor’s degree in Criminal Justice, Cybersecurity, or a related field, or equivalent experience.
• 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 related platforms.
• 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 and the ability to work across diverse teams, including HR, Legal, and IT, to lead projects and investigations with minimal guidance.

Benefits

• Equity, performance-related bonuses for eligible employees, and comprehensive benefits.
• Medical, dental, and vision insurance, with employer contributions to Health Savings Accounts.
• Pre-tax accounts for health and dependent care expenses, as well as commuter expenses.
• 401(k) retirement plan with employer match.
• Paid parental, medical, and caregiver leave.
• Paid time off, company holidays, office closures, and paid sick or safe time.
• Mental health and wellness support.
• Employer-paid basic life and disability coverage.
• Annual learning and development stipend.
• Daily meals in offices and eligible meal delivery credits.
• Relocation support for eligible employees.
