Senior Scientist, Biocatalysis

Job Description

The Biocatalysis group within the Small Molecule Process Research & Development Department in Rahway, New Jersey is seeking a Senior Scientist to expand our capabilities to design and deliver world‑class biocatalytic solutions that enable the development of medicines. Our group applies and advances biocatalysis and associated core technologies to invent, develop, and implement sustainable synthetic routes across the small molecule pipeline.

Our interdisciplinary team integrates biosynthetic logic, mechanistic investigation, data‑rich experimentation, molecular biology, biochemistry, bioinformatics, and advanced automation to drive innovation in drug discovery and development. By collaborating across process chemistry, chemical engineering, and analytical chemistry, we are transforming how molecules are made through innovative biocatalytic processes. The ideal candidate has deep expertise in biocatalysis or enzyme engineering, or a related discipline with a demonstrated ability to translate scientific innovations into practical solutions.

The group collaborates broadly within our Company, with academic leaders, and with industry partners to expand and accelerate the impact of biocatalysis on human health.

In this role, the successful candidate will contribute directly to the invention, development, and implementation of novel enzymes, biocatalytic reactions, and synthetic processes to support drug discovery, clinical supply, and commercial manufacturing. As part of multidisciplinary project teams, they will develop novel biocatalytic processes that enable efficient and scalable routes for drug development. The candidate will independently design and execute experiments, define novel approaches to challenging scientific problems, and work in teams to advance the application of biocatalysis for the benefit of the pipeline.

They will give scientific presentations internally and externally, contribute to publications and patents, contribute to defining the scientific strategy on programs, and develop new approaches that accelerate research and development while advancing the fields of enzyme engineering and biocatalysis.
