A clinical-stage biotechnology company headquartered in the Bay Area is seeking a highly skilled, proactive High-Throughput Synthetic Chemist to join its Discovery Synthesis team. This role will support a small-molecule research pipeline through the design and rapid delivery of high-quality compounds (milligram to multi-gram scale) to accelerate structure-activity relationship (SAR) exploration. We are particularly interested in chemists who have applied modern synthetic technologies to solve complex problems, including areas such as photocatalysis, electrochemistry, or transition metal catalysis, ideally within high-throughput or parallel experimentation environments. Location: South San Francisco, CA (Onsite) Key Responsibilities Design and synthesize small-molecule analogs to support SAR campaigns. Develop and execute efficient synthetic routes, including multi-step syntheses and late-stage diversification strategies. Utilize parallel or high-throughput approaches to generate focused compound libraries. Troubleshoot and optimize challenging reactions with scientific rigor and independence. Scale synthesis of intermediates and final compounds from milligram to decagram quantities. Collaborate closely with Medicinal Chemistry and cross-functional project teams to advance program goals. Coordinate with external CRO partners to plan and troubleshoot synthetic activities. Purify and characterize compounds using NMR, LC-MS, and related analytical techniques. Maintain high-quality electronic lab documentation suitable for IP and regulatory standards. Clearly communicate experimental rationale, progress, and results to internal and external stakeholders. Qualifications M.S. or Ph.D. in Organic Chemistry or related discipline with 4+ years of pharmaceutical or biotechnology industry experience. Strong foundation in modern synthetic organic chemistry with demonstrated application of enabling technologies (e.g., photocatalysis, electrochemistry, transition metal-mediated transformations). Experience with parallel synthesis, high-throughput experimentation, or automated reaction platforms preferred. Proven ability to design and execute robust, scalable multi-step syntheses. Experience delivering high-quality compounds across varying scales. Prior experience working effectively with CRO partners. Excellent documentation practices and strong analytical interpretation skills.
