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 required

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 integral collaboration

- Meaningful contribution to how AI understands science at an advanced level

- Potential for ongoing work and contract renewal
