About this role · Stem
About the Role We're looking for PhD-level Biochemists to help train and refine cutting-edge AI models on advanced scientific topics. Your deep domain expertise will directly shape how AI reasons through complex biochemical problems — from protein folding to metabolic flux — making a real impact on the future of AI in life sciences. This is a fully remote, flexible contract role. No prior AI experience required. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Design Advanced Problems: Create challenging biochemistry problems across domains like nucleic acid chemistry, proteomics, enzyme kinetics, and drug-target interactions to rigorously test AI performance. - Author Ground-Truth Solutions: Write precise, step-by-step technical solutions that serve as benchmarks for high-level AI scientific reasoning. - Audit AI Outputs: Evaluate AI-generated biochemical pathways, molecular structures, and mathematical proofs for technical accuracy, safety, and scientific integrity. - Refine AI Reasoning: Identify logical errors — such as incorrect stoichiometry, flawed stereochemistry, or misapplied biological principles — and provide structured feedback to improve AI reasoning in life science contexts. Who You Are - Advanced Degree: PhD (completed or in final stages) in Biochemistry, Molecular Biology, or a closely related field. - Deep Domain Knowledge: Strong expertise in one or more areas such as structural biology, enzymology, cellular metabolism, bioinformatics, or molecular genetics. - Strong Scientific Writer: Able to communicate complex biological and chemical concepts clearly, precisely, and concisely in written form. - Detail-Oriented: High level of precision when working with chemical equations, molecular diagrams, and experimental reasoning. - No prior AI experience required — we'll get you up to speed. Nice to Have - Experience with data annotation, data quality, or evaluation workflows - Familiarity with computational biochemistry tools such as PyMOL, AlphaFold, or BLAST - Background in science writing, peer review, or technical editing Why Join Us - Work on intellectually stimulating problems at the frontier of AI and life sciences - Fully remote and asynchronous — work on your own schedule - Collaborate with a global network of subject matter experts and AI researchers - Gain firsthand exposure to how advanced large language models are trained and evaluated - Freelance perks: autonomy, variety, and the flexibility to fit this around your existing commitments - Potential for ongoing work and contract extension
