Job Description

Health Physicist red-teaming Mercor’s frontier AI models on radiological safety and misuse detection. Writing technical prompts, evaluating responses, and producing reference rationales.

Responsibilities:

  • Write challenging single-turn prompts in the health physics domain across benign, dual-use, and adversarial levels
  • Evaluate model responses against a defined policy standard
  • Judge whether responses handled technical requests correctly
  • Write reference answers explaining correct responses and the technical reasoning behind them
  • Distinguish routine professional questions from requests indicating potential misuse
  • Apply practical experience in survey, assay, contamination control, and work planning to red-team frontier AI models
  • Provide written rationales that non-specialists can follow
  • Read and write about misuse scenarios in health physics for sustained periods

Requirements:

  • Background as an operational health physicist at a DOE site, national laboratory, or reactor facility, including survey, assay, and contamination control
  • Experience as an internal dosimetry or bioassay specialist, including intake assessment, dose reconstruction, and committed dose
  • Experience as a decommissioning and D&D health physicist, including characterisation surveys, MARSSIM, and release criteria
  • Experience in accelerator or reactor health physics, including activation products, neutron fields, and shielding design and verification
  • Experience with dose planning for high-hazard work, including RWP development, ALARA reviews, hot-cell, and glovebox operations
  • Ability to write challenging single-turn prompts labelled benign, dual-use, and adversarial
  • Ability to evaluate model responses against a defined policy standard
  • Ability to write reference answers with technical reasoning understandable to non-specialists
  • Prior technical writing, published research, or expert witness experience is a strong signal
  • Must not use classified, export-controlled, NDA-covered, or prepublication-review information
  • Must disclose such obligations so the work can be scoped accordingly

Benefits:

  • Earn up to $250 for each successful referral
  • No limit on how many people you can refer
  • Reasonable accommodations upon request
