You will contribute to evaluating frontier AI models as a nuclear fuel cycle expert. Your role will consist of writing nuanced technical questions and judging whether the model's answers comply with a safety policy, distinguishing between legitimate requests and potentially dangerous queries. This work requires a deep understanding of the parameters that differentiate a civilian application from a diversion for proliferation purposes.
Posted September 14, 2026
This job involves evaluating the capacity of AI models to distinguish legitimate requests from malicious uses in the field of nuclear medicine and medical isotopes. You will write nuanced test prompts and judge whether the model's responses comply with a security policy, while explaining your decisions in writing. This role requires specialized expertise to draw the line between routine professional questions and those concealing dangerous intentions.
Posted September 14, 2026
You will participate in evaluating cutting-edge AI models as a nuclear security specialist. You will write calibrated test prompts across three risk levels to judge whether the model correctly distinguishes legitimate professional questions from dangerous requests, then you will evaluate and document its responses according to a defined policy standard.
Posted September 14, 2026
You write political reports and election forecasts from a defined date, documenting the judgments an experienced analyst would have formed at that precise moment, without access to subsequent events. This role is aimed at recognized specialists in election forecasting, polling analysis, or political risk, capable of assessing probabilities of victory and explaining the causal mechanisms of political and market impacts.
Posted September 14, 2026
You are an engineer specialized in propulsion and pyrotechnic systems. You will write calibrated technical questions to test an AI model's ability to distinguish legitimate requests from bypass attempts, then evaluate its responses and document the technical reasoning that justifies each judgment.

This research study recruits current or former public defenders to describe in detail your daily work and responsibilities with clients in economically precarious situations. Participants will complete structured surveys about how you organize your tasks and may be selected for a later phase of data refinement, all compensated hourly.
Posted September 14, 2026
Join a team of radiation safety experts to test the robustness of AI models against requests related to dual-use applications. You will write nuanced evaluation questions, assess model responses against strict safety criteria, and document your technical judgment to distinguish legitimate requests from dangerous ones.
Posted September 14, 2026
Mercor is looking for nuclear and safeguards experts to test the robustness of AI models against dual-use requests. You will write targeted prompts on the knife's edge between legitimate professional questions and dangerous requests, then evaluate the model's responses against a defined policy and write reference answers. This role is for practitioners with concrete experience in nuclear material verification and detecting diversion attempts.
Posted September 14, 2026
You will contribute to evaluating frontier AI models as a source security specialist. Your role is to write prompts that test the model's ability to distinguish legitimate professional questions from potentially dangerous requests, then evaluate its responses against a defined policy standard. This work requires practical expertise in Category 1 and 2 radioactive source security, as well as strong technical writing skills to justify your assessments.
Posted September 14, 2026
You will contribute to evaluating AI models as a specialist chemist in energetic materials, by writing technical requests that test the model's ability to distinguish legitimate questions from dangerous requests. You will need to master the fine line between civilian applications and misuse to design realistic scenarios and evaluate the model's responses.
Posted September 14, 2026
You will write questions and scenarios to test an AI model's ability to correctly judge the potential for misuse of technical requests in chemistry, distinguishing legitimate questions from dangerous requests. This role requires practical expertise as a synthetic chemist or process engineer with experience scaling up reactions, and the ability to write clear technical justifications for non-specialists.
