The job description

About the Role

What if your years of chemistry expertise could directly shape how AI reasons through complex scientific problems — from undergraduate fundamentals to PhD-level research? We're looking for Chemistry Experts to help evaluate and improve the scientific reasoning of cutting-edge AI models, ensuring they think rigorously, accurately, and like a true scientist.

This is a fully remote, flexible contract role built for PhD-level chemists who want to apply their knowledge in a new and impactful way. No AI background required — your deep subject matter expertise is what matters.

What You'll Do

Design advanced chemistry problems spanning areas such as organic chemistry, biochemistry, chemical engineering, thermodynamics, and more
Develop rigorous, step-by-step solutions that demonstrate expert-level reasoning and logical precision
Evaluate AI-generated responses for scientific accuracy, depth of reasoning, and quality of explanation
Identify gaps, errors, and weaknesses in AI outputs and provide structured, actionable feedback
Collaborate with researchers to build and refine benchmarks across undergraduate to PhD-level chemistry topics
Work independently and asynchronously — fully on your own schedule

Who You Are

Pursuing or holding a PhD in Chemistry, Chemical Engineering, Biochemistry, or a closely related field
Strong problem-solving skills across advanced chemistry domains with the ability to reason from first principles
Able to communicate complex scientific ideas clearly and precisely in writing
Naturally detail-oriented — you notice when reasoning is flawed, incomplete, or imprecise
Self-motivated and reliable when working independently
No prior AI or machine learning experience required

Nice to Have

Experience in data annotation, data quality assessment, or evaluation systems
Background in academic research, curriculum development, or scientific writing
Familiarity with AI tools or language model evaluation workflows
Expertise spanning multiple chemistry subfields

Why Join Us

Work on cutting-edge AI projects alongside leading research labs and AI teams
Fully remote and flexible — work when and where it suits you
Freelance autonomy with the structure of meaningful, intellectually stimulating work
Make a direct, tangible impact on how AI understands and applies scientific knowledge
Gain exposure to how large language models are trained and evaluated
Potential for ongoing work and contract extension as new projects launch
