About White Circle

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.

What you'll do

• Own White Circle's content strategy and editorial direction

• Turn customer conversations into case studies, customer stories, and reference materials

• Interview customers, partners, founders, and engineers to uncover insights worth sharing

• Write and publish long-form content across Medium, Substack, LinkedIn, X, and our website

• Develop technical and non-technical content explaining AI safety, evaluation, governance, and reliability

• Create launch narratives for new products, features, and research initiatives

• Work closely with GTM team to support sales conversations and market positioning

• Help founders maintain a consistent public voice across LinkedIn, X, conferences, and other channels

• Build repeatable processes for content creation, publication, and distribution

• Experiment with new formats, channels, and ways of reaching technical audience

We're looking for someone who

• Can take a complex technical topic and explain it clearly without oversimplifying it

• Can independently identify what is worth publishing and what isn't

• Is comfortable interviewing executives, engineers, researchers, and customers

• Has experience creating content for technical audiences

• Can move comfortably between strategic thinking and hands-on writing
