San Francisco, CA | New York City, NY / San Francisco, CA, San Francisco, California, United States2025-10-09

About the job

We are looking for ML Engineers and Research Engineers to help detect and mitigate misuse of our AI systems. As a member of the Safeguards ML team, you will build systems that identify harmful use—from individual policy violations to sophisticated, coordinated attacks—and develop defenses that keep our products safe as capabilities advance. You will also work on systems that protect user wellbeing and ensure our models behave appropriately across a wide range of contexts.

Responsibilities

Develop classifiers to detect misuse and anomalous behavior at scale. This includes developing synthetic data pipelines for training classifiers and methods to automatically source representative evaluations to iterate on

Build systems to monitor for harms that span multiple exchanges, such as coordinated cyber attacks and influence operations, and develop new methods for aggregating and analyzing signals across contexts

Evaluate and improve the safety of agentic products—developing both threat models and environments to test for agentic risks, and developing and deploying mitigations for prompt injection attacks

Conduct research on automated red-teaming, adversarial robustness, and other research that helps test for or find misuse

Qualifications

Minimum

Have 4+ years of experience in ML engineering, research engineering, or applied research, in academia or industry

Have proficiency in Python and experience building ML systems

Are comfortable working across the research-to-deployment pipeline, from exploratory experiments to production systems

Are worried about misuse risks of AI systems, and want to work to mitigate them

Have strong communication skills and ability to explain complex technical concepts to non-technical stakeholders

Preferred

Language modeling and transformers

Building classifiers, anomaly detection systems, or behavioral ML

Adversarial machine learning or red-teaming

Interpretability or probes

Reinforcement learning

High-performance, large-scale ML systems
