Nuclear and Radiological Security Expert

You will provide specialist guidance for AI training work involving nuclear safety evaluations, radiological safety, nonproliferation, security standards, and sensitive technical information. The work includes turning complex nuclear-security concepts into clear standards and defensible decision frameworks.

You will also help define how nuclear and radiological risks are evaluated, abstracted, escalated, and documented so advanced models can handle these topics responsibly.

• Define evaluation scopes and standards for nuclear safety, radiological safety, nonproliferation, and security.
• Develop safe methods for abstracting sensitive or classified information in technical contexts.
• Set escalation thresholds and protocols for nuclear security risks in research and operational scenarios.
• Guide benchmarking of nuclear and radiological risk assessments and support nonproliferation safeguards.
• Review, refine, and validate technical guidelines used in advanced-model training.
• Work with multidisciplinary stakeholders on scientific progress and nuclear security considerations.
• Document best practices, compliance considerations, and the reasoning behind information-security decisions.

This is a part-time contractor role for an experienced nuclear or radiological security specialist. The role requires strong technical judgment, clear communication, and experience working with sensitive technical subjects.

• Pay: $50 to $90 per hour.
• Work type: Part-time contract work.
• Location: Open to candidates in AE, AR, AT, BD, BE, BH, BR, CA, CH, CL, CO, DE, DK, DZ, EG, ES, FR, GB, GH, GR, ID, IN, IT, JO, JP, KE, KG, KW, KZ, LB, LK, MA, MX, MY, NG, NL, OM, PE, PH, PK, PS, PT, QA, SA, SG, TH, TN, TW, US, UZ, VN, and ZA.
• Language: Professional fluency in English.
• Experience: At least five years in nuclear physics, radiological safety, nonproliferation, or nuclear safeguards.
• Education: An advanced degree, professional certification, or equivalent operational experience in a nuclear or radiological field.
• Background: Experience with government agencies, national laboratories, regulatory bodies, or academic research involving nuclear security or policy.
• Knowledge: Strong understanding of nonproliferation frameworks, international safeguards, and weapons-relevant controls.
• Assessment experience: Security evaluations, compliance protocols, or risk assessments in sensitive technical environments.
• Communication: Exceptional written and verbal communication, including explaining complex technical subjects to varied audiences.
• Helpful experience: Incident review, investigations, risk assessment, safety review, adversarial thinking, red-team work, or abuse prevention.
• Senior contributors may bring eight to twenty years of relevant experience and recognized credibility in nuclear or radiological safety communities.
