Protection Scientist Engineer, Integrity

About the Position

Protection Scientist Engineer, Integrity

San Francisco

About the Team

The Integrity team is responsible for the scaled systems that help identify and respond to bad actors and harm on OpenAI’s platforms. We protect users and the wider world by developing responses to complex harms and building the harm protections needed for new product and model launches. Integrity’s work spans not only across frontier harms like biological weapons and cybersecurity, but also high severity abuses such as child safety, nation-state misuse, and violence.

About the Role

Protection Scientists within Integrity design, orchestrate, and mature systems of defence against usage harms enabled by OpenAI's products. We are systems thinkers that combine deep harm domain expertise with breadth across investigation, data science, machine learning, policy, and operations. Our distinctive strength is understanding how these disciplines fit together and translating between them to design and build effective systems of defence.

Your core hands-on technical responsibility is harm detection. You will design, build, evaluate, and maintain production detection systems, drawing on investigative expertise, data, and shared engineering platforms. You will develop signals, classifiers, and detection systems, and improve their ability to identify harmful activity accurately as products and behavior evolve.

You will also own the strategy and cross-functional delivery of protection work for a harm area or product launch. Working closely with investigators and other domain experts, you will ground the design in a deep understanding of how the harm occurs and translate that understanding into a system of defence. You will connect detection with policy, review, interventions, enforcement, and measurement, continually calibrating the system against real cases and expert judgement as it scales.

You will identify what needs to be built or changed and make it happen. Success requires setting clear priorities, aligning partners, resolving dependencies, and communicating evidence, decisions, and trade-offs crisply. It also requires a willingness to jump in and work directly on whatever is blocking system effectiveness, using your breadth of skills.

This role is based in our SF, NYC, or London offices and includes participation in an on-call rotation that may involve resolving urgent escalations outside normal working hours. Some investigations may involve sensitive content, including sexual, violent, or otherwise disturbing material.

Responsibilities

• Define and drive protection strategy for a harm area or launch. Translate ambiguous risks into goals, priorities, and roadmaps, and make trade-offs based on evidence, risk, and available capacity.
• Directly build and maintain harm detection. Develop production signals, classifiers, and pipelines using SQL, Python, machine learning, and language models, integrating with shared engineering platforms.
• Lead cross-functional execution. Translate between specialist roles, establish shared understanding and ownership, resolve technical and organizational dependencies, and communicate recommendations and specific asks clearly.
• Investigate emerging harms and abuse patterns. Work with world-class domain experts to distinguish harmful activity from legitimate use, develop detection criteria, and inform policies and review protocols with Policy and Operations partners.
• Evaluate and improve the complete system of defence. Measure remaining harm, detection quality, and intervention effectiveness and collaborate with Data Science on more sophisticated metrics. Use expert feedback and operational outcomes to guide improvements.
• Protect product and model launches. Define data, detection, and review requirements; establish monitoring; investigate gaps and critical escalations; and drive improvements informed by post-launch findings.
• Scale effective approaches with language models, agents, and reusable tools. Choose where automation and human judgement are needed, and build documentation and processes that improve reliability and help others extend the work.

Requirements

• Think in systems. You have enough breadth across technical, analytical, investigative, and operational disciplines to understand how they fit together, recognize gaps, and translate between specialist perspectives.
• Bring deep expertise in at least one relevant harm domain, developed through integrity, trust and safety, security, investigations, or related work. You approach unfamiliar problems with curiosity and respect for expert knowledge and are driven by reducing harm.
• Are proficient in SQL and Python and have experience writing reliable and efficient production code for detection and data processing. Additional ML or SWE experience is a plus.
• Can apply quantitative analysis and machine-learning methods to measure risks and evaluate system effectiveness. You understand the limitations of your data and can reason about missed harms, false positives, and appropriate interventions. Additional DS/measurement background is a plus.
• Have experience setting strategy and delivering complex, cross-functional technical projects. You can turn an ambiguous problem into a plan, align people with different priorities, and drive work through to completion.
• Communicate clearly and concisely in writing and conversation. You can explain technical findings, make actionable recommendations, and surface uncertainty and trade-offs to different audiences.
• Can use language models and other automation to scale analytical, investigative, or operational work, with evaluation and human oversight appropriate to the problem.

We Offer

• Competitive salary
• Opportunity to work in one of our offices in San Francisco, New York City, or London
• Participation in an on-call rotation
• Professional growth opportunities
