The job description

About the Role

Your deep expertise in biochemistry is exactly what the next generation of AI needs. We're partnering with the world's leading AI research labs to train and refine cutting-edge models on advanced scientific topics — and we need PhD-level biochemists to help us get it right.

This is a fully remote, flexible contract role where your knowledge of protein folding, metabolic flux, enzyme kinetics, and molecular genetics directly shapes how AI reasons about life science. No AI background required — just rigorous scientific thinking and a passion for accuracy.

What You'll Do

Design Advanced Problems: Create challenging biochemistry problems spanning nucleic acid chemistry, proteomics, structural biology, and drug-target interactions to rigorously test AI performance.
Author Ground-Truth Solutions: Write detailed, step-by-step technical solutions that serve as benchmarks for high-level scientific reasoning within AI systems.
Audit AI Outputs: Evaluate AI-generated biochemical pathways, molecular structures, and mathematical proofs for technical accuracy, safety, and adherence to scientific standards.
Refine AI Reasoning: Identify logical errors — such as incorrect stoichiometry, misunderstood stereochemistry, or flawed mechanistic reasoning — and provide structured feedback to improve AI thinking for life science tasks.

Who You Are

Advanced Degree: PhD (completed or in final stages) in Biochemistry, Molecular Biology, or a closely related field.
Domain Expert: Strong foundational knowledge in one or more core areas such as enzymology, structural biology, cellular metabolism, or bioinformatics.
Clear Communicator: Able to explain highly technical biological and chemical concepts in precise, well-structured written form.
Detail-Oriented: High level of precision when reviewing complex chemical equations, molecular diagrams, and experimental protocols.
No prior AI experience required.

Nice to Have

Experience with data annotation, quality evaluation, or scientific peer review
Familiarity with computational biochemistry tools such as PyMOL, AlphaFold, or BLAST
Background in science writing, teaching, or curriculum development

Why Join Us

Work on high-impact AI projects alongside top research labs and teams
Fully remote and flexible — design your own schedule around your life
Freelance autonomy with global collaboration and variety in your work
Gain hands-on exposure to advanced large language models and how they're trained
Potential for ongoing work and contract extension
