TL;DR: We're hiring a DevRel Lead to make White Circle the AI safety platform engineers and researchers actually want to build with. You'll own how we show up to technical audiences: shipping technical content, running hackathons and meetups, launching open-source tools like Halo, and building partnerships across the AI ecosystem.
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, taking our total funding to $70M. Our investors include 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 developer relations: how engineers and AI researchers discover, understand, and adopt what we build
- Lead technical launches for open-source releases and developer tools, like our Halo framework, from narrative and demos through to launch day
- Write and publish technical content: blog posts, tutorials, walkthroughs, demos, and threads on X and LinkedIn
- Organise and run hackathons, meetups, and technical events, mainly in SF and New York
- Build and grow a technical community around our open-source work and platform
- Set up and run technical partnerships and collaborations with AI labs, dev tools companies, and research teams
- Give technical input to promo and product videos, working with our design and creative team on production
- Track what's working (signups, repo stars, views, event turnout, hiring pipeline) and double down on it
WE'RE LOOKING FOR SOMEONE WHO
- Has a strong technical background as a software engineer, ML engineer, or researcher
- Has worked at a technical product company, ideally in dev tools, infrastructure, databases, or AI
- Has organised hackathons, meetups, or technical events, and can show how they went (turnout, signups, what came out of them)
- Has an engaged following among engineers and/or AI researchers on X, LinkedIn, GitHub, or elsewhere
- Knows the AI tooling landscape well: coding agents, eval frameworks, open-source models, and who is building what
- Can take a complex technical topic and make it compelling for a developer audience without dumbing it down
- Thrives with ownership and moves fast without waiting for direction
- Is based in the US, or able to work US hours. SF or New York is ideal, but we'll consider exceptional candidates anywhere
- Is fluent in English
A big plus
- You've led developer marketing or DevRel for a technical launch that drove real adoption
- You've contributed to or maintained popular open-source projects
