About White Circle

We process over 100M+ API calls every month and have raised $11M from top funds, founders, and senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, Sentry, and others.

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 fine-tune and train our own LLMs so they run faster and cheaper than any open or proprietary model.

We’re at a multi-million dollar run rate already having signed customers like Lovable and multiple neobanks. You’ll be joining at the most exciting time - early enough that the equity can be life changing but at a point where demand has been proven.

We’re a small, highly focused team. If you want to work deeply on hard problems and build the category-defining company in AI safety – this role is for you.
