How to apply for DevRel Lead (Developer Relations)

About White Circle

White Circle builds the safety, reliability, and optimization layer for AI systems. The company has raised a $70M Series A and processes over 100 million API calls per month. It trains its own LLMs so they run faster and cheaper than open or proprietary models. Investors include senior leaders at OpenAI, Anthropic, HuggingFace, Mistral, DeepMind, Datadog, and Sentry.

About the role

You own how engineers and AI researchers discover, understand, and adopt White Circle's platform. You ship technical content, run hackathons and meetups, launch open-source tools like Halo, and build partnerships across the AI ecosystem. The role directly shapes how AI safety is built and used by developers.

A typical day

A typical day might include writing a tutorial or demo for a new feature, reviewing a pull request for an open-source tool, and planning a hackathon or meetup with partners. You may also join calls with engineering to understand what is shipping and how to explain it to developers. The role is remote and full-time, so expect async communication across time zones.

Who White Circle is looking for

• Has shipped technical content or developer tools that engineers actually used, such as tutorials, SDKs, demos, or open-source projects.
• Can run developer-facing events like hackathons and meetups, from planning through follow-up.
• Understands AI safety concepts such as policies, testing, enforcement, and model optimization, and can explain them to technical audiences.
• Has built partnerships or community relationships across the AI ecosystem, including researchers, tool builders, or platform teams.

Tips for this application

• Show a portfolio of technical content you wrote or shipped, such as blog posts, docs, videos, or open-source contributions. Link to live examples.
• Describe a specific developer tool or open-source launch you led. Include what you did, the adoption numbers, and what you learned.
• Name the AI developer communities, conferences, or meetups you are active in. White Circle wants someone already connected to the ecosystem.
• Explain how you would position White Circle against other AI safety and observability tools. Show you understand the developer audience.
• Mention any experience with policies, LLM testing, or model optimization. These are core to White Circle's platform.

What to cover in your cover letter

['A concrete example of a technical launch you owned, including the content, the channel, and the result.', 'Your approach to running hackathons or meetups that produce real adoption, not just attendance.', "How you would explain White Circle's policy-based AI safety platform to an engineer in one paragraph.", 'Why you want to work at a small, focused team where work ships to production quickly.']

Research before applying

• Read White Circle's product pages and documentation to understand how policies work and what the platform tests and enforces.
• Look up Halo and any other open-source tools White Circle has released. Check their GitHub activity and community response.
• Review the backgrounds of the investors listed, especially the operators from OpenAI, Anthropic, and HuggingFace, to understand the company's network.
• Find recent talks, posts, or interviews from White Circle team members to learn how they talk about AI safety and developer adoption.

Likely interview topics

Based on the job description, expect questions about:

• How would you launch an open-source tool like Halo to get engineers to try it and keep using it?
• Walk us through a technical content piece you wrote. How did you decide the topic, format, and distribution?
• How do you measure developer relations success beyond vanity metrics like views or event signups?
• How would you explain White Circle's policy system to an AI researcher who is skeptical of safety tooling?
• Describe a partnership you built in the AI ecosystem. What was the goal and what happened?

Common mistakes to avoid

• Writing a cover letter that talks about AI safety in general without mentioning White Circle's policy-based approach or its developer tools.
• Listing community management experience without showing technical depth or examples of content you personally created.
• Applying with no links to past work. For a DevRel role, the portfolio is the application.
