Cinder builds safety infrastructure for some of the most important AI and internet platforms in the world, including Midjourney, ElevenLabs, Synthesia and Black Forest Labs. We’re backed by Accel, Y Combinator, and Radical Ventures.

We’re building a network of specialists who test AI models for the ways they can cause real harm. When a customer project calls for your expertise, we bring you in on a paid, project-based contract.

We want to hear from:

• Red teamers and jailbreakers with hands-on experience getting frontier models to break

• Testers with experience across image, video, and audio generation, or in agentic and MCP-connected systems

• Experts in specific domains, including child safety, CBRNE, violent extremism, NCII, cybersecurity, fraud, self-harm, psychology, and copyright

• Native speakers who can test models in languages and cultural contexts beyond English

Projects vary in size and timing. Once you’re in the network, we’ll reach out when a project matches your background.

Compensation: $50 – $150 per hour • Rates will vary based on experience, expertise, and location. What is shown here is a broad estimate for an expert based in New York, NY.
