## Job description

## About White Circle

[White Circle](https://whitecircle.ai/) 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

## Why White Circle

- Meaningful salary and equity package
- Paid time off in line with your local regulations, no matter where you work from
- All the hardware, tools, and services you need
- Full coverage for educational subscriptions
- Team off-sites twice a year: we’ve recently been to the Alps and to Saint-Tropez

## How we hire

- Intro call with HR (25 min)
- Take-home assignment
- Final conversation with our CEO and Head of Design (45 min)
- an additional interview with one or more team members may be added depending on the interview process

Along with your application, please send us 3 pieces of writing you're most proud of and tell us why you chose them.
