Job Description

Experience: Director

Salary: $75 - $100 per hour

Job Details

Key Responsibilities and Duties

• Review AI generated responses covering nuclear and radiological topics, including fuel cycle, criticality, reactor systems, special nuclear material, safeguards, shielding and emergency response, for technical accuracy, safety framing and guideline alignment
• Flag outputs that provide dangerous procedural detail, material acquisition or diversion guidance, weaponization support, safeguards or detection evasion, or other misuse enabling content
• Create gold standard reference content that answers benign nuclear questions responsibly without introducing operationally sensitive detail
• Evaluate and rank model outputs on safe handling, correct risk framing, appropriate refusals, helpful redirection, scientific accuracy and clarity
• Detect hallucinated claims, incorrect physics, wrong units or activity figures, misleading risk statements, overconfident conclusions and unsafe recommendations
• Apply project rubrics consistently and provide clear written feedback explaining why content is safe, unsafe, incomplete or technically incorrect
• Ensure content uses precise nuclear terminology and communicates risk without exaggeration or minimization
• Escalate ambiguous, high risk or potentially harmful content for additional review per project guidelines
• Contribute across adjacent chemical, biological and radiological content where your background supports it

Qualifications Needed

• Bachelor's degree or higher in Nuclear Engineering, Physics, Mechanical Engineering, Health Physics, Radiation Science or a related field, or equivalent professional experience
• Minimum 3 years of professional experience in nuclear engineering, nuclear safety, criticality safety, reactor operations, fuel cycle, safeguards, decommissioning or technical review
• Experience or strong background in nuclear safety basis, criticality safety, radiological risk assessment, shielding, material control and accountability, or reactor systems
• Strong background in identifying unsafe instructions, operationally enabling detail, inappropriate specificity, misleading technical claims and unsupported conclusions
• Proven ability to evaluate technical content for accuracy, completeness and policy alignment, and to explain that judgment in precise written English
• Professional English proficiency at C1 minimum, sufficient to follow written guidelines and produce detailed written feedback
• Familiarity with 10 CFR 830, 10 CFR 50 Appendix B, NQA-1, DOE nuclear safety orders, NRC licensing, or IAEA safeguards concepts preferred
• Professional Engineer licensure, reactor operator licensure, or an active or recent DOE or DoD clearance preferred
• Prior experience with AI safety, data annotation, technical QA, policy review, risk assessment, red team review, scientific review or rubric based evaluation strongly preferred
• Reliable and self directed, able to deliver consistent quality in an hourly remote contractor workflow
• Must be a citizen of the United States, United Kingdom, Australia or New Zealand

A bit about us:

We are partnered with a fast growing AI data services company that builds the training and evaluation data behind many of the world's leading AI labs and foundation model developers. Their work sits where technical expertise meets model safety, bringing in specialists from nuclear engineering, radiation science, chemistry, biology and emergency response to evaluate how AI systems handle high consequence subject matter. The experts on these projects determine where these models should answer, where they should decline, and how they should reason about nuclear and radiological risk. They operate remotely across time zones and build their review teams around people who are already practicing in their field. We are helping them identify nuclear engineering specialists for this engagement.

Why join us?

• Competitive Hourly Compensation: Up to $100 per hour as an independent contractor
• Paid Onboarding: You are paid for the onboarding program, not only for project work
• No Interview Process: Candidates we put forward go directly into paid onboarding
• Keep Your Current Role: Structured as supplemental work. No requirement to leave your position
• 100% Remote, Flexible Hours: Set your own schedule and volume across time zones
• Direct Impact on Nuclear Safeguards: Your judgment determines where these models draw the line on nuclear and radiological questions
• Work Inside Your Expertise: Technical review and reference writing in your own discipline, not general purpose data work
• Growing Engagement: An expanding program with continued need across all four CBRN domains
