1. What is a Research Scientist at Catalent Pharma?

The Research Scientist role at Catalent Pharma is a pivotal position that sits at the intersection of scientific innovation and rigorous quality standards. As a member of the Catalent Pharma team, you are responsible for executing complex laboratory procedures, developing and validating analytical methods, and ensuring that all work adheres to strict cGMP (current Good Manufacturing Practice) guidelines. Your work directly impacts the development and manufacturing of life-saving pharmaceutical products, making accuracy, documentation, and technical proficiency essential.

This role is both challenging and rewarding due to the scale and complexity of the projects you will encounter. You will often work within a Contract Development and Manufacturing Organization (CDMO) environment, which means you must be comfortable managing multiple priorities, collaborating with cross-functional teams like Quality Assurance (QA) and Laboratory Operations, and adapting to the fast-paced nature of client-driven projects. Whether you are performing HPLC analysis, protein purification, or method development, your contribution is critical to ensuring the integrity and safety of the drug delivery solutions Catalent Pharma provides to patients worldwide.
