About the Role We're looking for chemistry experts to help train and evaluate cutting-edge AI models being developed by the world's leading AI research labs. Your deep domain knowledge will directly shape how AI understands and reasons through complex chemistry problems — from undergraduate fundamentals to advanced graduate-level concepts. No AI experience required. If you can think rigorously about chemistry, you're already qualified. - Organization: Alignerr - Type: Hourly Contract - Location: Remote - Commitment: 10–40 hours/week What You'll Do - Design challenging, high-quality chemistry problems to test the limits of AI reasoning across domains like chemical engineering, biochemistry, organic chemistry, and more - Develop clear, step-by-step solutions with rigorous logic and detailed explanations - Evaluate AI-generated responses for scientific accuracy, depth of reasoning, and overall quality - Collaborate with researchers to refine benchmarks spanning undergraduate through Master's-level chemistry topics - Provide structured, constructive feedback that helps improve AI model performance 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, self-motivated, and comfortable working independently - No prior AI or data annotation experience required Nice to Have - Experience with data annotation, evaluation systems, or quality review workflows - Familiarity with large language models or AI tools - Background spanning multiple chemistry subfields Why Join Us - Work on genuinely cutting-edge AI projects with top-tier research labs - Fully remote and asynchronous — work on your own schedule, from anywhere - Freelance flexibility: choose your hours, scale up or down as needed - Make a direct, meaningful contribution to how AI understands science - Potential for ongoing work and contract renewals
