About the Role

Mercor is assembling a panel of chemistry and chemical safety experts to red-team frontier AI models. The goal is to test whether a model can correctly judge the misuse potential of a technical request — answering legitimate questions fully while refusing genuinely dangerous ones.

What You'll Do

  • Write challenging single-turn prompts in your domain, labelled across three levels: benign, dual-use, and adversarial.
  • Evaluate the responses that come back against a defined policy standard, and judge whether each was handled correctly.
  • Write the reference answer — what a correct response looks like, and the technical reasoning for why.
  • This domain lives on the dual-use line more than most. The same route design that scales a medicine underpins a controlled compound; the same impurity profile that proves a clean process identifies how something was made. A model that refuses a routine scale-up or kinetics question is failing as badly as one that answers a question it shouldn't. Drawing that line reliably is why we need practitioners rather than generalists.

You're a Good Fit If You

  • We're looking for chemists who have actually run routes and scaled them — bench to pilot to plant — and who know which requests are ordinary process chemistry and which are asking for something else. What matters most is being able to tell a routine professional question from one that's fishing for something else: the same route knowledge that shortens a synthesis serves whoever is shortening it. You will be writing prompts that sit exactly on that line, then judging whether the model held it.
  • Examples of relevant backgrounds (ideally with red-teaming experience):
  • Synthetic route design and development in pharmaceutical, agrochemical or fine chemicals
  • Process chemistry and reaction engineering — optimisation, kinetics, impurity control
  • Scale-up from bench to pilot to plant, with the safety review that goes with it
  • Precursor sourcing, controlled-substance registration or regulatory chemistry
  • Method development and troubleshooting in a GMP or equivalent quality environment
  • What this role demands beyond technical depth
