Recruiter

TLDR: We’re looking for a Recruiter to help us build one of the strongest teams in AI safety. You’ll own full-cycle hiring across engineering, AI research, product, and business roles, partnering with Head of HR and hiring managers to attract exceptional talent across the US and Europe.
 
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:
Own full-cycle recruitment from sourcing through offer acceptance

Source and engage exceptional talent across the US and European markets
