## About the work Mercor is assembling a panel of energetic materials and propulsion 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. You will: - 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 formulation work that qualifies a propellant or a display composition sits next to something nobody should be helped with; the same sensitivity data that protects a production line reads as a specification from the other side. A model that refuses a routine…

This domain lives on the dual-use line more than most.

AfterQuery is building a network of PhD-level and PhD-pursuing researchers to author and calibrate research-grade evaluation tasks for AI models. A strong task is a real piece of computational work from your own research — something you have actually run, debugged, or been paid to do: data reduction, model fitting, simulation setup, instrument data processing, numerical solvers, or inverse problems. The difficulty should come from the science itself, not from artificially withheld information. We are commissioning tasks across five broad areas: Life sciences (biology, ecology, medicine, neuroscience), Physical sciences (astronomy, chemistry, materials science, physics), Earth sciences (atmospheric, environmental, geosciences, ocean), Mathematical sciences (applied mathematics, formal mathematics, operations research, statistics), and Engineering sciences (chemical, civil, electrical, mechanical).

**About the role** This is an evaluation framework for frontier AI models in drug research and development. Domain experts write realistic research problems wrapped around messy evidence worlds. The model works offline in a sandbox with open-source scientific tooling, receiving incomplete, indirect and sometimes misleading data, and must reach a defensible conclusion. The answer is present in the evidence but never stated. Your job is to build a research problem so realistic and well-constructed that the model has to genuinely reason to solve it — it can't pattern-match or look the answer up. **What you'll deliver** Three things per task: the prompt, the data room, and the grading document. 1. **Design the challenge** — identify the hidden basin and the forcing chain that makes one conclusion inevitable. 2. **Build the world** — assemble a data room from real, source-grounded data. Every decisive value traces to a real source. 3. **Write the grader** — a grading document that scores…
