Job description

Models routinely propose impossible mechanisms, unsafe procedures, and syntheses that no bench chemist would attempt.

As a Chemist you'll evaluate AI chemical reasoning, catch what's wrong or unsafe, and write the answers a trained chemist would give.

What you’ll actually do

• Write prompts that probe chemical reasoning: mechanisms, synthesis routes, and analytical interpretation.
• Review AI output for impossible mechanisms, unsafe procedures, and misread spectra, and rate the reasoning.
• Write the correct answer when the model falls short, with proper attention to conditions and safety.

What we look for

• Graduate-level chemistry background or equivalent lab experience.
• Comfort across organic, inorganic, or physical chemistry.
• Clear written English: your explanations are the training signal.
• No degree required. We care about what you can do, not where you learned it.
