PhD Synthetic and Analytical Chemist, AI Expert (Remote, UK or US East Coast)

• PhD in Chemistry, preferably in Synthetic Chemistry, Organic Chemistry, Medicinal Chemistry, Analytical Chemistry, Physical Chemistry, or a closely related discipline. Equivalent research experience may also be considered.
• At least 3 years of hands-on chemistry experience within a recognized organization, such as a pharmaceutical, biotechnology, chemical, or materials company, contract research organization, or university research group.
• Strong practical experience in small-molecule synthesis, including:
• Designing and executing multi-step synthetic routes.
• Reaction setup, monitoring, and optimization.
• Troubleshooting experimental challenges and improving reaction outcomes.
• Hands-on experience with analytical and compound-characterization techniques, including:
• Nuclear Magnetic Resonance (NMR) spectroscopy.
• Mass spectrometry.
• Infrared (IR) spectroscopy.
• High-Performance Liquid Chromatography (HPLC).
• Liquid Chromatography–Mass Spectrometry (LC-MS).
• Ability to interpret analytical and spectroscopic data and assess compound identity, purity, and structural characteristics.
• Familiarity with cheminformatics platforms, scientific software, and AI-powered research tools. Programming expertise is not required.
• Strong written communication skills, with the ability to explain complex chemical concepts and technical decisions clearly.
• Ability to commit reliably to at least 20 hours per week during weekdays.

• Experience working with cheminformatics representations and molecular notations such as SMILES and SMARTS.
• Familiarity with AI model evaluation, scientific reasoning assessments, or AI agent testing.
• Experience developing scientific benchmarks, training datasets, grading rubrics, or structured evaluation frameworks.
• Ability to translate complex laboratory procedures and chemical reasoning into clear, structured technical documentation.

• →Collaborate with AI research and engineering teams to identify scientific knowledge gaps and improve model performance across synthetic chemistry, reaction mechanisms, structure elucidation, and physicochemical property prediction.
• →Design challenging, domain-specific chemistry tasks, benchmarks, and training datasets that assess genuine scientific reasoning rather than simple information retrieval.
• →Develop accurate, structured solutions for complex chemistry problems, including multi-step synthesis route planning, reaction optimization, and spectroscopic characterization.
• →Evaluate AI-generated responses and step-by-step reasoning, identifying errors in chemical logic, factual accuracy, and scientific tool usage.
• →Provide detailed written technical feedback to improve the reliability and scientific accuracy of AI model outputs.
• →Develop task specifications, grading rubrics, and verification processes for chemistry-related data produced by external technical teams.
• →Assess experimental designs, identify common laboratory failure modes, and validate the chemical feasibility of proposed solutions.
• →Review molecular representations, including SMILES, for chemical correctness and consistency.
• →Collaborate with other subject-matter experts to maintain scientific accuracy and quality across AI training datasets.
