Selected role

Data Scientist, Safety

OpenAI London, UK

Senior Full-time

About the Team

OpenAI’s Safety teams work to ensure our products are safe, trusted, and resilient as frontier AI systems scale globally. We tackle some of the company’s most important challenges across understanding and preventing misuse and misalignment, intercepting fraud and abuse, and protecting vulnerable users.

We are hiring Data Scientists to help build the analytical foundations that allow OpenAI to deploy increasingly capable AI responsibly.

This is a high-impact role operating at the intersection of product, safety, policy, and research.

About the Role

As a Data Scientist, Safety, you will help solve complex and ambiguous problems where rigorous analysis directly informs critical decisions.

Depending on your background and team alignment, you may work on areas such as:

Measure harmful or abusive behavior across OpenAI’s products
Detect fraud, manipulation, coordinated misuse
Evaluate and improve safety classifiers, rules systems, mitigation systems, and human review workflows
Design experiments and causal analyses to understand product, policy, and mitigation impacts
Build prevalence estimators, dashboards, monitoring systems, and executive decision frameworks
Diagnose gaps in safety and integrity systems using behavioral and product data, and help quantify and navigate false positive / false negative tradeoffs
Translate ambiguous safety risks into measurable problems and evidence-based recommendations
Partner with Product, Engineering, Policy, Research, and Operations teams to improve safety outcomes
Build zero-to-one analytical systems in rapidly evolving domains

Ideal Candidate

We’re looking for strong Data Scientists who thrive in ambiguous, high-leverage environments.

You may be a fit if you have:

Strong statistical reasoning and analytical judgment
Experience with experimentation, causal inference, or observational analysis
Strong SQL and Python skills
Experience working with messy, incomplete, or noisy datasets
Ability to structure open-ended business or risk problems
Excellent communication with technical and non-technical stakeholders
High ownership and comfort operating independently

Helpful backgrounds include:

Trust & Safety / Integrity
Fraud & abuse
Security analytics
AI/ML model measurement and evaluation
Alignment and AI safety research
Biosecurity, synthetic biology, infectious diseases, or computational biology

Why This Role

Work on mission-critical problems with world-level impact
Help shape how frontier AI systems are deployed safely
Operate with unusual ownership and visibility
Solve novel problems where there are no existing playbooks
Join highly collaborative teams working across OpenAI
