About this role, in Alignerr's words
What if your deep expertise in biochemistry could help shape the next generation of AI? At Alignerr, we partner with the world's leading AI research labs to build smarter, more scientifically accurate AI models — and we need PhD-level biochemists to make it happen.
What you'll do
- Design Expert-Level Problems — Create challenging biochemistry problems across domains like nucleic acid chemistry, proteomics, structural biology, and drug-target interactions to rigorously stress-test AI performance.
- Author Gold-Standard Solutions — Write precise, step-by-step technical solutions that serve as the scientific benchmark AI models are trained to replicate.
- Audit AI Reasoning — Evaluate AI-generated biochemical pathways, molecular structures, and quantitative analyses for accuracy, safety, and scientific integrity.
- Refine AI Thinking — Identify flaws in AI reasoning — such as incorrect stoichiometry, misapplied stereochemistry, or faulty metabolic logic — and provide structured feedback that directly improves model performance.
Candidate background
Who You Are
- Advanced Degree: PhD (completed or in progress) in Biochemistry, Molecular Biology, or a closely related field.
- Deep Domain Knowledge: Strong foundations in one or more of structural biology, enzymology, cellular metabolism, bioinformatics, or molecular genetics.
- Clear Scientific Writer: Able to communicate complex biochemical and chemical concepts accurately and concisely in written form.
- Detail-Oriented: High precision when reviewing chemical equations, molecular diagrams, reaction mechanisms, and experimental protocols.
- No prior AI or data annotation experience required.
