Remote Chemistry Researchers (Part-time) - AI Trainer ($125-$225 per hour)

We are recruiting a select cohort of accomplished chemistry researchers to contribute to the next generation of AI systems for scientific reasoning. Our partner labs are building models that need to reason about organic synthesis, mechanism, catalysis, structural and physical chemistry, chemical biology, computational and theoretical chemistry, and materials at the level of a working researcher — not a textbook. To get there, they need contributors whose own research sits at the frontier. This is a W-2 employment position with Cincinnatus LLC, requiring a part-time commitment of 8 to 20 hours per week. This position will be placed at a leading AI lab as part of their extended workforce. What you’ll do Author and review challenging chemistry problems used to train and evaluate frontier AI models. Evaluate model outputs on tasks ranging from retrosynthesis and mechanism prediction to spectral interpretation, computational chemistry, and literature reasoning. Surface areas where current models fail — especially the kinds of mistakes a working PhD chemist would catch immediately. Collaborate with a small program team and other senior contributors. The level we’re hiring at First-author or co-first-author publications in journals at the level of JACS, Nature Chemistry, Science, Nature, Angewandte Chemie, Nature Catalysis, ACS Catalysis, Chem (Cell Press), Chemical Reviews, Chem Soc Rev, JOC, Org Lett, Inorg Chem, Nature Communications, JPC family, or top specialty journals. Doctoral or postdoctoral training at a top-20 global institution for chemistry or STEM. Competitive fellowships such as NSF GRFP, Hertz, Sloan Research Fellow, Camille and Henry Dreyfus, Searle Scholar, Pew Scholar, Beckman Young Investigator, NIH F32 / NRSA, Damon Runyon, Helen Hay Whitney, Marie Curie, Fulbright, Rhodes, Marshall, Gates Cambridge, Schmidt Science Fellow, Knight-Hennessy, SNSF Postdoc, NSF CAREER, DOE Early Career, or equivalent. Issued patents, spin-out companies, or grants where the contributor was a named PI or co-PI. International Chemistry Olympiad (IChO) Gold/Silver/Bronze medalist. Currently or recently in an active research role: PhD candidate, postdoc, instructor, faculty, principal scientist, or industry researcher. Outstanding senior PhD students and recent graduates with strong publication records are explicitly encouraged to apply — years of experience matter less than the depth of the research output. Engagement Part-time: 8 to 20 hours per week. W-2 employment with Cincinnatus LLC; payroll, benefits, and compliance handled by Cincinnatus. Compensation reflects research seniority and credentials. No fixed end date; contributors continue as long as the program needs their expertise. Equal Employment Opportunity Cincinnatus LLC is proud to be an Equal Employment Opportunity employer.
