Security Engineer - Threat Intelligence

About the Team

Security is at the foundation of OpenAI’s mission to ensure that artificial general intelligence benefits all of humanity.

The Threat Intelligence team protects OpenAI’s technology, people, research, and infrastructure by proactively identifying and disrupting adversaries who seek to compromise our systems or misuse our models. We investigate sophisticated threats, build tooling to scale and augment analysis, and deliver intelligence that shapes security strategy and equips leadership with timely, risk-aware insights. We combine technical depth, investigative rigor, and strong cross-functional partnerships to uncover threats and drive impact across OpenAI’s security and research organizations.

About the Role

As a Technical Threat Investigator at OpenAI, you will help defend the company from a full spectrum of threats — from nation-state actors and cybercrime groups to adversaries attempting to misuse our models.

In this role, you’ll conduct deep investigations into adversary operations. You’ll track sophisticated threat actors, produce high-signal reporting, build agentic workflows, and collaborate across the security org and wider company. Your work will directly inform our security strategy and shape how threat intel teams operate in the future.

This is a remote role with close collaboration required across teams in the US and UK. While the role is remote, regular in-person engagement with our San Francisco (SF) headquarters will be expected. Relocation assistance is available for candidates who wish to relocate to SF.

In this role, you will:

• Track, disrupt, analyze, and deeply understand sophisticated adversaries targeting OpenAI.

• Conduct investigations using security telemetry, internal safety systems, and a variety of enrichment sources.

• Build lightweight tooling, automations, agentic workflows, and leverage our models to scale investigation capabilities for the company.

• Produce high-quality, actionable threat intelligence reports for internal stakeholders.

• Collaborate closely with Detection & Response, Infrastructure Security, Insider Risk, and other investigative teams.

• Evolve threat models and investigative approaches across software, infrastructure, and hardware layers as adversaries adapt and innovate.

• Identify gaps in telemetry or tooling and propose scalable improvements.

You might thrive in this role if you have:

• Significant experience tracking and investigating sophisticated adversaries (e.g., APTs, cybercrime groups).

• Strong scripting ability (e.g., Python, Bash) to accelerate investigations.

• Familiarity with hardware-level threats and infrastructure-focused attack surfaces (e.g., firmware, BMCs, supply chain risks).

• Practical experience with SIEMs, telemetry pipelines, and threat enrichment platforms.

• Familiarity with modern adversary tactics, techniques, and procedures across infrastructure, cloud, and endpoint environments.

• Ability to independently drive investigations from low-fidelity leads to finished intelligence products.

• Strong written and verbal communication skills, especially translating technical investigations into actionable intelligence for diverse stakeholders.

• Comfortable navigating ambiguity and driving forward independently in high-pressure or uncertain situations.
