Biochemist

About the Role

Your years of rigorous scientific training are more valuable than ever — and not just in the lab. We're looking for PhD-level Biochemists to help train and refine some of the world's most advanced AI models on cutting-edge scientific reasoning.

At Alignerr, we partner with leading AI research teams to build models that can think like experts. That means we need real experts — people who can spot when an AI gets enzyme kinetics wrong, misunderstands stereochemistry, or produces a flawed metabolic pathway. If that's you, this role was built for you.

This is a fully remote, flexible contract role. No AI experience required — just deep biochemistry knowledge and sharp analytical thinking.

What You'll Do

• Create challenging biochemistry problems spanning protein folding, nucleic acid chemistry, metabolic flux analysis, proteomics, and drug-target interactions to rigorously stress-test AI performance.
• Write precise, step-by-step technical solutions that serve as the scientific benchmark for AI reasoning in life sciences.
• Evaluate AI-generated biochemical pathways, molecular structures, and mathematical derivations for scientific accuracy, logical consistency, and safety.
• Identify and document reasoning failures such as incorrect stoichiometry, stereochemical errors, or flawed enzyme mechanisms, and provide structured feedback that directly improves model quality.

Who You Are

• Advanced Degree: PhD (completed or in progress) in Biochemistry, Molecular Biology, or a closely related discipline.
• Deep Domain Knowledge: Strong expertise in one or more of the following — structural biology, enzymology, cellular metabolism, molecular genetics, or bioinformatics.
• Scientific Writer: Ability to communicate complex biological and chemical concepts clearly, precisely, and concisely in written form.
• Meticulous Attention to Detail: High precision when reviewing chemical equations, molecular diagrams, reaction mechanisms, and experimental protocols.
• No AI experience required — we'll guide you through everything you need to know.

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 bioinformatics or cheminformatics
