Chemistry Masters – AI Data Trainer
About The Role
We're looking for Master's-level chemistry experts to help train and improve some of the world's most advanced AI models. Your scientific knowledge will directly shape how AI understands and reasons through complex chemistry — from organic synthesis to biochemical pathways.

This is a fully remote, flexible contractor role. No AI experience required — just deep chemistry expertise and the ability to think critically and communicate clearly.

Organization: Alignerr

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week

What You'll Do

Design challenging, high-quality chemistry problems to rigorously test AI reasoning and performance

Develop clear, step-by-step solutions with well-structured logic across domains such as chemical engineering, biochemistry, and physical chemistry

Evaluate AI-generated responses for scientific accuracy, depth, and quality of reasoning

Collaborate with researchers to build and refine benchmarks spanning undergraduate through Master's-level chemistry topics

Provide structured, actionable feedback that helps improve AI model outputs over time

Who You Are





Currently pursuing or have completed a Master's degree in Chemistry, Chemical Engineering, Biochemistry, or a closely related field

Strong problem-solving skills across advanced chemistry domains

Able to communicate complex scientific concepts clearly and precisely in writing

Detail-oriented and consistent when evaluating technical content

Self-motivated and comfortable working independently on an async schedule

No prior AI experience

Nice to Have

Experience with data annotation, data quality review, or evaluation systems

Familiarity with large language models or AI research workflows

Background spanning multiple chemistry sub-disciplines

Why Join Us

Work on cutting-edge AI projects in partnership with leading AI research labs

Fully remote and flexible — work on your own schedule, from anywhere

Freelance perks: high autonomy, variety of projects, and general collaboration

Meaningful contribution to how AI understands science at an advanced level
