About the work

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.

Responsibilities

• 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.

Background we're looking for

We’re looking for people who have worked chemical threats from the defensive side in an institutional setting — countermeasures, protection, detection, verification. What matters most is being able to tell a routine professional question from one that’s fishing for something else: the same agent properties that drive a treatment protocol drive a threat assessment. You will be writing prompts that sit exactly on that line, then judging whether the model held it.

• Chemical defence research at USAMRICD, DoD, CDC or an allied national institute
• Toxicology of chemical warfare agents and medical countermeasure development
• Decontamination, protection and detection research for chemical threats
• CWC-related work — verification, destruction, designated laboratory analysis
• Consequence assessment and medical management of chemical exposure

What this role demands beyond technical depth

This is writing-intensive work. Every judgment you make needs a written rationale that a non-specialist can follow. Prior technical writing, published research, or expert witness experience is a strong signal; please include a sample or link. You will also be reading and writing about misuse scenarios in your field for sustained periods. We brief experts on this in advance, and you can pause or step away at any point without penalty.

Before you apply

Your work here will not involve, and must not draw on, classified or export-controlled information, or anything covered by an NDA or prepublication review obligation. If you hold such obligations you may still be a good fit; tell us in your application and we will scope the work accordingly.

We consider all qualified applicants without regard to legally protected characteristics and provide reasonable accommodations upon request.
