Job Description

Our client is an AI safety start-up developing the safety, reliability, and optimization layer for advanced AI systems. At the core of the platform is a natural-language policy engine—clear rules that define what an AI model should and shouldn’t do. These policies are automatically tested, enforced, and continuously improved at scale.

The company has raised significant funding from leading VC as well as founders and senior leaders across top AI labs and tech companies.

Its systems handle hundreds of millions of API calls every month, and the team trains and fine-tunes its own LLMs to run faster and more efficiently than both open-source and proprietary alternatives.
