About us
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.
You will:
- Coordinate meetings, calendars, and inboxes
- Handle travel planning (flights, hotels, logistics)
- Research and compare services, products, etc.
- Book reservations, appointments, and meetings
- Handle operational and administrative tasks quickly and independently
- Organise information and summarise options clearly
- Help reduce day-to-day operational friction across a wide variety of areas

- Can make decisions independently without needing detailed instructions
- Communicate clearly and concisely
