Why AI training matters in medicinal chemistry

AI systems that assist drug discovery and molecular research learn from high-quality, expert-reviewed examples. Human specialists—bioinformaticians, chemists, and data scientists—prepare, curate, and evaluate those examples so models make scientifically accurate recommendations.

This role gives you direct influence on model behavior in a fast-growing field where careful annotation, domain expertise, and clear feedback accelerate safer, more reliable AI for chemistry and biology.

The role

OpenTrain is hiring a remote contractor Bioinformatics Scientist with medicinal chemistry expertise. You will analyze complex biological, chemical, and clinical datasets, curate and validate drug-discovery data, and review AI-generated scientific content for accuracy and reliability.

This is a part-time contractor role requiring 20+ hours per week. Compensation is hourly, USD $90–$120/hr (top rate $120/hr). Work is document-focused and includes classification, named-entity and entity-classification tasks, plus evaluation/rating of model outputs.

What you'll do

• Analyze medicinal chemistry datasets using bioinformatics and cheminformatics methods to extract and validate key information.
• Curate, annotate, and validate drug-discovery and molecular analysis data to create high-quality training examples.
• Review AI-generated scientific content for accuracy, relevance, and reliability; identify factual or methodological issues.
• Provide clear written recommendations and feedback to guide model improvements and data curation standards.
• Advise on experimental design, data interpretation, and annotation guidelines where subject-matter expertise is required.

Requirements

Applicants must meet the core technical and domain requirements below. OpenTrain hires contractors worldwide; English fluency is required for documentation and feedback.

This role is labeled part-time contractor work (20+ hrs/week) with hourly pay in USD. The work is document-centric and uses classification, entity/NER classification, and evaluation/rating tasks.

• Advanced degree (MSc or PhD) in bioinformatics, computational biology, medicinal chemistry, or a closely related discipline.
• Strong understanding of medicinal chemistry, structure–activity relationships, and drug design principles.
• Experience working with large-scale omics or cheminformatics datasets and applying bioinformatics methods.
• Familiarity with Python, R, RDKit, KNIME, databases, and related bioinformatics/cheminformatics tools.
• Excellent scientific communication and clear written feedback skills; experience in multidisciplinary or remote projects.

Helpful background

Research experience at the intersection of biology, chemistry, and data science is a strong plus. Practical familiarity with cheminformatics pipelines, molecular descriptors, and assay data curation will help you be productive quickly.

Comfort working independently as a contractor and translating technical findings into concise guidance for annotators and model teams will accelerate impact.
