Health Physicist for AI Model Red-Teaming

SaidGig; New York (NY); Remote; USD 90,000 - 103,000; Full time

Job summary

SaidGig is seeking a health physics expert to help evaluate frontier AI systems by distinguishing legitimate radiological safety questions from those with misuse potential. The role is remote and per-task, requiring hands-on experience in health physics to craft realistic scenarios and define safe, technically sound responses.

You will evaluate model outputs, draft comprehensive reference answers with technical rationale, and apply professional judgment to separate routine dose/shielding

Qualifications

• Hands-on measurement, dose planning, survey work, assay, contamination control, and precise work planning in critical environments.
• Red-teaming experience is preferred and valued.

Responsibilities

• Develop challenging single-turn prompts in radiological safety, classified as benign, dual-use, or adversarial.
• Evaluate model responses against a defined policy standard and determine whether each response was handled correctly.
• Write reference answers that describe the appropriate response and the technical reasoning behind it.
• Apply professional judgment to distinguish routine questions from requests that may conceal harmful intent.

Job description

Role Overview

Help evaluate frontier AI systems’ ability to distinguish legitimate radiological safety questions from requests with genuine misuse potential. This remote, per-task role draws on hands-on health physics expertise to create realistic technical scenarios, assess model responses, and define what safe, technically sound answers should look like.

Key Responsibilities

• Develop challenging single-turn prompts in radiological safety, classified as benign, dual-use, or adversarial.
• Evaluate model responses against a defined policy standard and determine whether each response was handled correctly.
• Write reference answers that describe the appropriate response and the technical reasoning behind it.
• Apply professional judgment to distinguish routine questions, such as dose, shielding, or isotope-use questions, from requests that may conceal harmful intent.

Qualifications

• Relevant experience includes hands-on measurement, dose planning, survey work, assay, contamination control, and work planning in environments where accuracy is critical. Red-teaming experience is preferred.
• Operational health physics experience at a DOE site, national laboratory, or reactor facility, including survey, assay, or contamination control.
• Internal dosimetry or bioassay experience, including intake assessment, dose reconstruction, or committed dose.
• Decommissioning or D&D health physics experience, including characterization surveys, MARSSIM, or release criteria.
• Accelerator or reactor health physics experience involving activation products, neutron fields, or shielding design and verification.
• Dose planning for high-hazard work, including RWP development, ALARA reviews, hot-cell operations, or glovebox operations.

Writing Expectations

This is writing-intensive work. You must be able to explain each judgment in clear written rationale that non-specialists can understand. Technical writing, published research, or expert witness experience is strongly valued. Include a writing sample or link with your application.

Work Terms

• Remote engagement.
• Per-task work.
• The work involves sustained reading and writing about misuse scenarios in radiological safety. You will be briefed in advance and may pause or step away at any time without penalty.

Compensation

65 to 75 per task.

Eligibility

Work must not involve or rely on classified information, export-controlled information, material covered by an NDA, or material subject to prepublication review. Candidates with these obligations may still apply; identify them in your application so the work can be appropriately scoped.
