Software Engineer, Codex Cyber

Engineering on the security side of OpenAI's software engineering agent, building the product and platform foundations for AI-native application security. The posting describes the work as helping organisations find, validate, prioritise and fix real vulnerabilities in the software they build and depend on, rather than as security work on OpenAI's own systems. It sits inside the Codex group, so the role is building the agent's capabilities rather than applying it elsewhere.
