Job Description

Nuclear materials forensic scientist red-teaming frontier AI models for Mercor. Writing dual-use prompts, evaluating responses, and documenting technically rigorous reference answers.

Responsibilities:

  • Write challenging single-turn prompts in nuclear materials and safeguards, labelled benign, dual-use, or adversarial
  • Evaluate model responses against a defined policy standard
  • Judge whether responses handled technical requests correctly
  • Write reference answers explaining what a correct response looks like and the technical reasoning behind it
  • Develop prompts that distinguish legitimate professional questions from requests seeking harmful information
  • Provide written rationales that non-specialists can follow
  • Read and write about misuse scenarios in the field
  • Work only with unclassified, non-export-controlled information that is not covered by an NDA or prepublication review obligation

Requirements:

  • Experience characterising real nuclear material, including detection, attribution, and analytical work supporting defensible conclusions
  • Relevant background in nuclear forensics casework or international exercise participation
  • Experience with radiochemical and mass-spectrometric analysis, isotopics, age dating, impurity and process signatures
  • Experience with detection and interdiction technology, including portal monitors, handheld identification, or search operations
  • Experience with material signature libraries, reference materials, and attribution methodology
  • Pre- or post-detonation forensics research at a national laboratory or agency
  • Ability to distinguish routine professional questions from potentially malicious requests
  • Strong technical writing ability; every judgment must include a rationale understandable to a non-specialist
  • Prior technical writing, published research, or expert witness experience is a strong signal
  • Must not use classified or export-controlled information, NDA-covered information, or material subject to prepublication review obligations
  • Willingness to read and write about misuse scenarios for sustained periods
  • Red-teaming experience is ideally relevant
  • Include a technical-writing sample or link if available

Benefits:

  • Earn up to $250 for each successful referral
  • No limit on how many people you can refer
  • Reasonable accommodations upon request
  • Ability to pause or step away from misuse-scenario work at any point without penalty
