CBRN Specialist

About this role

Type: Contract Location: Remote Skills & technologies CBRN English Chemical Safety Biological Safety Radiological Safety Nuclear Safety AI Safety Risk Review Hazard Communication Emergency Preparedness Key responsibilities Review CBRN-related AI content: Evaluate AI-generated responses involving chemical, biological, radiological, nuclear, hazardous-material, emergency-preparedness, and public-safety topics for accuracy, safety, and guideline alignment.

Identify unsafe or enabling content: Flag outputs that provide dangerous procedural detail, acquisition guidance, weaponization support, evasion tactics, unsafe lab guidance, harmful exposure advice, or other misuse-enabling content. Develop safe reference content: Create gold-standard examples that answer benign CBRN questions responsibly while avoiding operationally dangerous instructions. Optimize AI safety behavior: Evaluate and rank model outputs based on safe handling, correct risk framing, appropriate refusals, helpful redirection, scientific accuracy, and clarity.

Ensure model integrity: Detect hallucinated claims, incorrect hazard classifications, misleading risk statements, overconfident conclusions, poor escalation guidance, or unsafe recommendations. Support policy-aligned review: Apply project rubrics consistently and provide clear written feedback explaining why content is safe, unsafe, incomplete, or technically incorrect. Maintain technical quality: Ensure CBRN-related content uses precise terminology, avoids exaggeration or minimization of risks, and communicates safety information in a responsible, user-appropriate way.

Escalate sensitive cases: Flag ambiguous, high-risk, or potentially harmful content for additional review according to project guidelines. Requirements: Bachelor’s degree or higher in Chemistry, Biology, Microbiology, Public Health, Toxicology, Nuclear Engineering, Radiation Science, Emergency Management, Environmental Health & Safety, Biosecurity, Security Studies, or a related field, or equivalent professional experience.

Strong professional proficiency in English, minimum C1, to follow guidelines and provide detailed written feedback in English. 3+ years of professional experience in CBRN safety, emergency preparedness, hazardous materials, biosafety, radiation safety, public health, environmental health and safety, defense/security analysis, technical review, or related work. Strong understanding of chemical, biological, radiological, and nuclear hazard categories, including safe high-level risk assessment, exposure pathways, protective concepts, emergency communication, and public-safety principles.
