Chemistry AI Training Specialist

A leading AI lab is advancing the frontier of generative AI by training Large Language Models to reason rigorously across scientific domains. This role offers an exciting opportunity for Chemistry / Scientific Domain Experts to leverage their hands-on chemistry expertise to enhance the quality of AI training and evaluation data. Key Responsibilities

• Design chemistry-focused tasks and model evaluation workflows that test scientific reasoning.
• Translate chemistry expertise into clear instructions, rubrics, grading criteria, and review processes.
• Read and synthesize scientific papers and technical materials.
• Evaluate model-generated outputs for scientific correctness, rigor, and usefulness; provide clear written technical feedback.
• Partner with research and engineering teams to improve data quality, evaluation design, and iteration loops.
• Collaborate with other subject matter experts to ensure consistency and accuracy in training data.

• PhD or equivalent research experience in chemistry (or a closely adjacent field such as chemical biology, materials chemistry, or computational chemistry).
• Strong scientific reasoning and the ability to assess correctness and rigor of chemistry-related claims, papers, and model outputs.
• Hands-on technical fluency with datasets, notebooks, Python, LLMs, and scientific software; able to move fluidly between scientific concepts and computational workflows.
• Ability to commit to 40 hours per week, fully onsite in San Francisco, for the duration of the 6-month engagement.
• Strong written communication skills and the ability to explain scientific decisions and methodological choices clearly.
• Bonus: experience in computational chemistry, cheminformatics, molecular modeling, or adjacent chemistry-focused computational research.
• Bonus: prior annotation/evaluation experience on 2 or more projects.
