Biochemist

Alignerr Corp.; Sheffield (TX); Remote; USD 83,000 - 138,000; Full time

Job summary

Alignerr is seeking a Biochemist to act as an AI Data Trainer, bringing deep domain knowledge to stress-test and benchmark AI models in life sciences.

You will design expert-level problems across nucleic acid chemistry, proteomics, and drug-target interactions, write precise ground-truth solutions, and audit AI outputs for scientific accuracy. This fully remote, flexible contract role offers freelance autonomy and the opportunity to influence how cutting-edge models are trained.

Qualifications

• PhD in Biochemistry, Molecular Biology, or closely related field (completed or in final stages).
• Strong foundational expertise in structural biology, enzymology, cellular metabolism, molecular genetics, or bioinformatics.
• Able to communicate highly technical biological and chemical concepts clearly in written form.
• Exceptionally detail-oriented when reviewing complex equations, molecular diagrams, and experimental protocols.

Responsibilities

• Design expert-level problems spanning nucleic acid chemistry, proteomics, structural biology, and drug-target interactions to stress-test AI performance.
• Author ground-truth solutions—write precise, step-by-step technical responses that serve as benchmarks for AI reasoning in life sciences.
• Audit AI outputs—evaluate AI-generated biochemical pathways, molecular structures, and derivations for scientific accuracy and safety.
• Refine AI reasoning—document failures in AI logic and provide structured feedback to improve model performance.

Job description

Biochemist – AI Data Trainer

About The Role

What if your expertise in protein folding, enzyme kinetics, or metabolic flux could help shape the next generation of AI? At Alignerr, we partner with the world's leading AI research teams to build smarter, more scientifically rigorous models — and we need PhD-level biochemists to make it happen.

This is a fully remote, flexible contract role where your deep domain knowledge becomes the benchmark that AI strives to meet.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

What You’ll Do

• Design Expert-Level Problems — Craft advanced biochemistry challenges spanning nucleic acid chemistry, proteomics, structural biology, and drug-target interactions to rigorously stress-test AI performance
• Author Ground-Truth Solutions — Write precise, step-by-step technical responses that serve as gold-standard benchmarks for AI reasoning in life sciences
• Audit AI Outputs — Evaluate AI-generated biochemical pathways, molecular structures, and mathematical derivations for scientific accuracy, safety, and adherence to established standards
• Refine AI Reasoning — Identify and document failures in AI logic — such as incorrect stoichiometry, flawed stereochemistry, or misapplied enzyme mechanisms — and provide structured feedback to improve model performance

Who You Are

• PhD in Biochemistry, Molecular Biology, or a closely related field (completed or in final stages)
• Strong foundational expertise in one or more of: structural biology, enzymology, cellular metabolism, molecular genetics, or bioinformatics
• Able to communicate highly technical biological and chemical concepts clearly in written form
• Exceptionally detail-oriented when reviewing complex equations, molecular diagrams, and experimental protocols
• Self-motivated and comfortable working independently in an async environment
• No prior AI experience required

Nice to Have

• Experience with data annotation, data quality review, or evaluation systems
• Familiarity with computational biochemistry tools such as PyMOL, AlphaFold, or BLAST
• Background in scientific writing, peer review, or technical editing

Why Join Us

• Work on high-impact AI projects alongside leading research labs
• Fully remote and flexible — set your own schedule and hours
• Freelance autonomy with meaningful, intellectually stimulating work
• Gain first-hand exposure to how cutting-edge large language models are trained and evaluated
• Potential for ongoing work and contract extension
