About the Job

Requirements

  • Bring substantial depth in cybersecurity or AI model evaluation, such as application security, penetration testing, vulnerability research, adversary simulation, red-team operations, designing and running evaluations, building agentic harnesses, automating adversarial testing, constructing datasets, or analyzing model behavior at scale.
  • Have working literacy across both cybersecurity and model evaluation, with interest in developing further depth outside the primary area.
  • Be able to write code and build practical testing tools, particularly for automating experiments, orchestrating models, or analyzing results.
  • Have an attacker mindset and interest in discovering failure modes that standard evaluations may not capture.
  • Have clear written and verbal communication skills, including the ability to explain technical findings, limitations, and risk to audiences with different backgrounds.
  • Have experience working across technical and non-technical teams to move from a finding to a decision, mitigation, or follow-up test.

Responsibilities

  • Design and run rigorous evaluations of model cyber capabilities and safeguards, including policy adherence, correct refusal, over-refusal, and resilience to jailbreaking and other adversarial techniques.
  • Conduct hands-on testing to understand what models can enable when used by experienced security practitioners, including through task-specific harnesses, scaffolding, and multi-step workflows.
  • Distinguish benchmark or policy failures from behavior that creates meaningful real-world risk, considering feasibility, attacker uplift, reliability, and capabilities already available elsewhere.
  • Build and improve automated testing infrastructure that supports repeatable measurement, rapid iteration, and statistically grounded analysis across models and product surfaces.
  • Test novel abuse risks in agentic systems, including indirect prompt injection, agent hijacking, and other ways adversaries may manipulate systems that use tools or act on external information.
  • Translate findings into clear risk assessments and actionable recommendations for Security, Research, Product, Policy, and Engineering partners.
  • Contribute a portion of time to Safety Bug Bounty work, particularly where reports require cyber expertise.

About the Company

OpenAI

Builds AI models and the ChatGPT assistant

OpenAI researches and builds artificial intelligence models and turns them into products for people, developers, and businesses, with a stated mission of making sure artificial general intelligence benefits all of humanity. Its launch of ChatGPT in 2022 brought generative AI into everyday use. People use ChatGPT to ask questions, write, code, and analyze files, developers build OpenAI's models into their own apps through its API, and its Codex agent works through coding tasks on its own. OpenAI earns money from ChatGPT subscriptions, business plans, and API usage. Sam Altman, Elon Musk, and others co-founded it in 2015; it is based in San Francisco and overseen by a nonprofit, the OpenAI Foundation.
