A bit about us

We are partnered with a fast growing AI data services company that builds the training and evaluation data behind many of the world's leading AI labs and foundation model developers. Their work sits where technical expertise meets model safety, bringing in specialists from chemistry, toxicology, process safety, biology and radiation science to evaluate how AI systems handle high consequence subject matter. The experts on these projects shape how frontier models reason about chemical hazard, exposure and public safety, and that reach extends well beyond any single plant or laboratory. They operate remotely across time zones and build their review teams around people who are already practicing in their field. We are helping them identify chemical safety and chemistry specialists for this engagement.

Why join us?

• Competitive Hourly Compensation: Up to $100/hr as an independent contractor, paid hourly
• Keep Your Current Role: Structured as supplemental work, not a career move. No requirement to leave your position
• 100% Remote, Flexible Hours: Set your own schedule and volume across time zones
• Direct Impact on Frontier AI Safety: Your judgment shapes how leading models handle chemical, biological, radiological and nuclear subject matter
