from OpenAI careers

About the team

The Applied Foundations team at OpenAI is dedicated to ensuring that our cutting-edge technology is not only revolutionary, but also secure from a myriad of adversarial threats. We strive to maintain the integrity of our platforms as they scale. Our team is at the front lines of defending against financial abuse, scaled attacks, and other forms of misuse that could undermine the user experience or harm our operational stability

The Integrity pillar within Applied Foundations is responsible for the scaled systems that help identify and respond to bad actors and harm on OpenAI’s platforms. We are creating a 0→1 team in London to architect next-generation systems that will support, leverage, and scale the work of experts in harms committed with our technology.

In this role, you will:

  • Design and build scaled foundational systems used in the detection, tracking, and enforcement of harm using our technologies.

  • Work closely with and learn from technical and non-technical experts on harms we are observing, and that stem from our platforms, to inform your designs and implementation.

  • Leverage OpenAI’s most advanced technologies to automate and augment our abilities to detect and reason about complex harms quickly, accurately, and with minimum human intervention.
