Expert Contributor - Chemistry (Task-Based)

About the role

Snorkel AI is a data development company spun out of the Stanford AI Lab, focused on improving the truthfulness and reasoning abilities of advanced AI systems. This ongoing project-based opportunity allows expert contributors to help shape the next generation of AI models by designing challenging tasks, stress-testing AI agents, and providing expert feedback that steers model behavior toward ideal solutions. No prior AI experience is required.

We are looking for Chemistry experts with the ability to design and solve challenging, real-world reasoning tasks that test the limits of advanced AI systems. Contributors will create high-quality chemistry problems, develop rigorous solutions, and help identify where models fail in scientific reasoning. The work is designed around graduate-level difficulty, scientific precision, and reproducible evaluation.

Requirements

• Deep fluency in Chemistry, with the ability to create graduate-level, multi-step analytical problems and produce precise, fully worked solutions.
• Strong review instincts — able to identify subtle scientific errors, suggest more rigorous approaches, and evaluate competing solution paths across multiple turns of a conversation.
• Master’s or PhD candidate, or graduate, in Chemistry or a related discipline.
• Background in one or more of: academic research, university-level teaching, advanced problem writing, laboratory science, or technical scientific communication.

Nice to have

• Familiarity with grading rubrics, olympiad- or exam-style question design, or evaluating AI-generated scientific reasoning.

Schedule

Remote 1099 contractor position with flexible, independent work and no set hours commitment. Must be eligible to work as a contractor and cannot reside in California.

Pay

Compensation is per accepted task rather than an hourly rate. Payments for this role range from $63 to $410 per task, with an average handling time of 60 to 390 minutes. Experts earn at least $15 per hour but have the opportunity to earn significantly more based on productivity and quality.
