About the Team

The Intelligence and Investigations team seeks to rapidly identify and mitigate abuse and strategic risks to ensure a safe online ecosystem. We are dedicated to identifying emerging abuse trends, analyzing risks, and working with our internal and external partners to implement effective mitigation strategies to protect against misuse. Our efforts contribute to OpenAI's overarching goal of developing AI that benefits humanity.

About the Role

As a Quantitative Intelligence Analyst, you will focus on discovering novel and emerging risks in complex human–AI systems before they are well-defined, measurable, or widely understood.

Responsibilities

• Discover and define new quantitative risk signals where no established metrics exist, using subject matter expertise to surface early, weak, or unconventional indicators

• Translate complex trust and safety challenges into measurable signals that can be tracked and stress-tested over time

• Develop upstream early-warning and signal frameworks that inform downstream detection and mitigation efforts

• Analyze risk trends to assess the underlying drivers and causal factors behind those changes

• Conduct data mining and statistical modeling to understand how risks originate, evolve, and propagate across systems

• Design adversarial scenarios, and quantitative stress tests to assess exposure, coverage gaps, and vulnerabilities

• Produce clear data-driven briefs to support risk prioritization, contingency planning, and strategic risk products across teams

Requirements

• Have 3–6+ years of experience in quantitative intelligence analysis, trust & safety, security analysis, or risk-focused research

• Are comfortable working on complex trust and safety domains such as child safety, violent activities, self-harm, or similar high-stakes risk areas

• Familiarity with data mining, statistical modeling, and supervised learning methods

• Understand how to monitor signals or models for data drift, behavioral adaptation, or performance degradation over time, and can diagnose likely causes

• Experience in operationalizing adversarial or strategic risk behaviors, including through red-team exercises, agent-based modeling, or structured scenario analyses

• Comfortable working with Python and SQL

• Nice to have: Experience with quantitative stress testing or Monte Carlo simulations to assess uncertainty and tail risk
