About This Type of AI Training Work

AI training (also called data labeling or human feedback work) is the human-centered process that teaches models to reason, follow safety frameworks, and produce reliable outputs. Experts like you provide evaluations, corrections, and guidance that become the examples models learn from.

This role focuses on evaluating text and model outputs related to chemical safety, toxicology, precursor chemicals, and nonproliferation—high-impact work that helps AI systems interpret hazardous-substance scenarios and regulatory guidance more accurately.

The Role

OpenTrain is recruiting Chemical Safety & Toxicology AI Training Experts to review, rate, and annotate text and model outputs used to train AI systems that assess chemical hazards and nonproliferation risks.

This is a remote, part-time contractor role requiring at least 20 hours per week. You will apply domain expertise to produce high-quality evaluations and contribute to guidelines that improve model safety and accuracy.

What You’ll Do

• Analyze and evaluate text, documents, and model outputs related to chemical safety, toxicological risk, precursor chemicals, and hazardous-substance scenarios.
• Review and annotate materials; provide structured evaluation ratings and written feedback to improve model behavior.
• Apply nonproliferation standards and regulatory protocols to assess risk, controlled-substance concerns, and mitigation strategies.
• Develop and refine guidelines for assessing chemical and toxicological hazards in real-world and hypothetical contexts.
• Explain complex chemical interactions, exposure pathways, and toxicity profiles in clear, usable language for AI training.
• Collaborate with project coordinators to clarify ambiguous content and address gaps or inaccuracies in datasets or model assessments.

Requirements

Candidates must meet the substantive qualifications below. We will preserve these core requirements to ensure high-quality, expert-led evaluations.

• Advanced degree required: PhD, MD, JD, PsyD, or a relevant master’s in chemistry, toxicology, industrial hygiene, or a closely related scientific discipline.
• Minimum 5 years of specialized experience in areas such as chemical weapons nonproliferation, hazardous materials handling, toxicological risk assessment, or chemical safety protocols.
• Experience working as an independent consultant, policy advisor, response specialist, or safety officer in industrial, governmental, or research settings.
• Demonstrated expertise in controlled substances, precursor risk evaluation, or nonproliferation regulatory frameworks.
• Excellent written and verbal communication skills with the ability to explain complex technical information clearly.
• Familiarity with established standards for chemical safety, hazardous material management, or toxicology operations in high-stakes settings.

Who Should Apply

This role is ideal for mid-career to senior professionals who want to apply domain knowledge to AI development—safety officers, toxicologists, industrial chemists, nonproliferation analysts, and experienced consultants.

If you have hands-on experience evaluating chemical risk, advising on regulatory compliance, or responding to hazardous-material incidents and you’re curious about helping AI systems learn from expert judgment, apply.

Compensation, Schedule, and Logistics

This contract, part-time role requires 20+ hours per week and is open worldwide for English-language work. Pay is hourly: $50–$90 USD per hour (listed range). You will perform text-based evaluation and rating tasks using the project’s annotation tools (labeled as OTHER).

Employment type: contractor, part-time. Labeling focus: text evaluation and structured rating tasks (EVALUATION_RATING). OpenTrain will match you with projects, and you’ll collaborate with coordinators to deliver high-quality, documented evaluations.
