Nuclear and Radiological Security AI Trainer

About OpenTrain

OpenTrain is the #1 platform for finding and building careers in AI training and data labeling. We help specialists discover projects, build a unified portfolio, and grow a durable freelance career teaching AI how to reason about complex, real-world topics.

This role is posted by OpenTrain through the OpenTrain platform and connects domain experts with high-impact AI safety work in a remote, flexible format.

Why AI training matters for safety

AI training (data labeling / human feedback) is the human side of building modern AI: experts create, review, and evaluate examples that teach models how to behave. Specialists in high-risk domains—like nuclear and radiological security—play an outsized role in ensuring models learn safe, lawful, and reliable reasoning.

Contributors commonly work remotely, choose flexible hours, and directly influence how advanced systems assess risk, flag hazards, and escalate sensitive issues to human operators.

The role

OpenTrain and OpenTrain are recruiting Nuclear and Radiological Security AI Trainers to shape next-generation AI systems that interact with nuclear and radiological safety topics. This contract, part-time position supports model evaluation and RLHF-style work focused on nonproliferation, safeguards, and secure information handling.

• Commitment: 20+ hours per week (part-time, contractor).
• Location: Remote — open globally; work is performed online.
• Pay: $50–$90 USD per hour (specified pay range).
• Labeling work: document-based tasks, evaluation ratings and RLHF-style review using external/other tooling.

What you'll do

You will apply deep domain knowledge to create standards, frameworks, and evaluations that help AI systems reason about nuclear and radiological risk without enabling misuse.

• Define evaluation scope and standards for nuclear and radiological safety, nonproliferation, and security.
• Develop frameworks for safe abstraction of sensitive or classified information in technical contexts.
• Establish robust escalation thresholds and protocols for handling nuclear security risks in research and operational scenarios.
• Contribute expert guidance on benchmarking nuclear and radiological risk assessments and nonproliferation safeguards.
• Review, refine, and validate technical guidelines used to train and evaluate advanced models.
• Collaborate with multidisciplinary stakeholders to balance safety, security, and legitimate scientific progress.
• Document best practices and decision rationales for information security and compliance in nuclear domains.

Requirements

We need trusted subject-matter experts with demonstrated experience in nuclear/radiological safety, safeguards, or nonproliferation who can translate technical judgment into evaluation criteria and escalation guidance.

• Minimum 5+ years relevant experience in nuclear physics, radiological safety, nonproliferation, or nuclear safeguards.
• Advanced degree, professional certification, or equivalent operational experience in a nuclear/radiological field.
• Proven background working with government agencies, national laboratories, regulatory bodies, or academic research in nuclear security or policy.
• Deep understanding of nonproliferation frameworks, international safeguards, and weapons-relevant controls.
• High credibility and recognition in nuclear or radiological safety communities.
• Exceptional written and verbal communication; able to translate complex technical topics for diverse audiences.
• Experience contributing to or overseeing security evaluations, compliance protocols, or risk assessments in sensitive technical environments.

Additional application details & who should apply

Ideal contributors include experienced practitioners who have led or participated in nuclear safety, safeguards, or nonproliferation assessments and who can help define safe AI behavior in these domains.

The posting notes a helpful background range of roughly 8–20 years for senior contributors, though candidates meeting the listed requirements are encouraged to apply.

• Candidates should be prepared to discuss relevant experience such as risk assessment, safety review, red-team or abuse-prevention work within nuclear security contexts.
• You will be asked about specific activities and examples during screening; do not disclose classified material as part of the application.

How the work is delivered

This contract role uses document-based evaluation and RLHF-style rating tasks performed through custom or third-party tooling. Work is remote and asynchronous; contributors receive task instructions, examples, and quality guidance.

OpenTrain connects you to the engagement and helps manage submission, feedback, and payment logistics; OpenTrain is the hiring organization for this project.

• Employment type: Contractor, part-time.
• Label types: Evaluation ratings and RLHF-style review of documents.
