Content Lead, 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 recently raised our Series A funding round of $70M (total funding of $81M) 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 vision and editorial direction
  • Turn customer conversations into case studies, customer stories, and reference materials
  • 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
  • Partner closely with product, as well as supporting wider business teams where needed
  • 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

  • Is an exceptional writer
  • Can take a complex technical topic and explain it clearly without oversimplifying it
  • Knows how to find interesting stories inside products, customers, and technology
  • Has strong editorial judgment
  • Can independently identify what is worth publishing and what isn’t
  • Has experience creating content for technical audiences
  • Can move comfortably between strategic thinking and hands-on writing
  • Is fluent in English

A big plus

  • You have an engineering, computer science, or technical background
  • You have built an audience through writing
  • You have a track record of making technical topics compelling, whether at a developer tools or AI company, in tech journalism, or through your own writing and audience
  • You’ve written content that materially influenced product adoption, company positioning, or revenue generation
