[Remote] Security Researcher, Trusted Computing and Cryptography at OpenAI

The Security Researcher will lead efforts to map, characterize, and prioritize cross-layer vulnerabilities in advanced AI systems, spanning data pipelines, training/inference runtimes, and system/supply chain components. This role involves driving offensive research, producing technical deliverables, and serving as the primary technical counterpart for external partners. Responsibilities include building an AI Stack Threat Map, delivering deep-dive reports on vulnerabilities and mitigations, orchestrating inputs across research, engineering, security, and policy, and performing hands-on threat modeling, red-team design, and exploitation research. The researcher will also translate complex technical issues for various audiences and brief on risk, impact, and mitigations.
