9h•$90 - $140•Remote

About The Position

This remote, U.S.-based contract role engages experienced PhD chemists and chemistry researchers to contribute scientific expertise to the development, evaluation, and advancement of AI models. The position involves working with AI research teams to improve models’ ability to understand and reason about chemistry and research. The work includes evaluating chemistry-related reasoning tasks and AI outputs, creating precise research-level problems and reference solutions, and developing benchmarks in the candidate’s area of specialization. The ideal candidate is an established academic or research professional with deep expertise in at least one chemistry domain, a strong peer-reviewed publication record, and hands-on experience using large language models in scientific or research workflows. The engagement is independent contractor work, fully remote, with a flexible schedule and weekly payments based on services rendered. Project duration may change based on business requirements and individual performance. The work does not require access to confidential or proprietary information belonging to a current or former employer, client, university, or research institution. H-1B and STEM OPT visa holders cannot be accommodated.

Requirements

PhD in Chemistry, Chemical Engineering, or a closely related scientific discipline.
Senior-level academic or research experience, such as a faculty appointment, Principal Investigator, Staff Scientist, Senior Scientist, or equivalent senior research position at a university, national laboratory, or established research organization.
Deep specialization in at least one of the following: organic and synthetic chemistry, physical chemistry, computational chemistry, inorganic chemistry, materials chemistry, analytical chemistry, chemical biology, or theoretical chemistry.
Strong peer-reviewed research publication record.
Hands-on experience using Large Language Models (LLMs) and AI tools in scientific, academic, or research workflows.
Strong analytical and critical-thinking abilities, including the ability to identify chemical inaccuracies and evaluate complex scientific reasoning.
Excellent written communication skills and ability to provide precise, structured, technically sound feedback.
Must currently be based in the United States.
