Role details
This Mercor listing is for chemistry subject-matter experts — including synthetic, organic, medicinal, analytical and physical chemists — to help design and evaluate advanced AI models for chemistry. It is described as a part-time role through Cincinnatus LLC, or an appropriate international entity, which the posting says would be the employer of record, with placement in a leading lab’s extended workforce.
The work described includes designing difficult, non-searchable chemistry tasks and writing accurate solutions (for example multi-step route design, reaction optimisation and spectroscopic characterisation); evaluating model outputs and step-by-step reasoning; writing grading rubrics; and advising on lab failure modes and chemical validity, including representations such as SMILES.
Who it is for
The posting asks for a PhD in chemistry or a closely related discipline, or equivalent research experience, plus at least three years of hands-on chemistry at a recognised organisation. It also asks for small-molecule synthesis experience and practical work with techniques such as NMR, mass spectrometry, IR and HPLC or LC-MS. At least 20 hours a week during weekdays is required. Coding is not required.
