White Circle is an AI Safety company building the safety, reliability, and optimization layer for AI systems. At the core of our platform are policies – simple natural-language rules that define what an AI model should and shouldn't do. We automatically test, enforce, and continuously improve these policies at scale.
We've raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others. We process over one hundred million API calls every month. We fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model.
We're a small, highly focused team. If you want to work deeply on hard problems, see your work ship to production quickly, and influence how AI safety is actually built – you're the one we need.
This role may involve reviewing content that is offensive, harmful, violent, sexual, or otherwise disturbing. We provide tooling, and support, but candidates should be comfortable working with sensitive content when necessary.
