Full time

We are growing our locations and are investing more than $40 million for a new facility in Watertown, Massachusetts. The new process development and manufacturing facility will focus on viral vectors and advanced therapies.

The new site will host experimental and analytical equipment needed for viral vector and advanced therapy process development. The contract manufacturing services for early phase clinical trials are planned to begin at the site in 2023.


  The Downstream Process Development Scientist I functions to assist in the planning of, execution, and interpretation of complex laboratory experiments and activities necessary for gene therapy, vaccine, and recombinant protein purification process development with priorities set by supervisor/project lead to achieve project goals. The individual may lead small customer or internal projects, and typically oversees the daily activities within ongoing projects under guidance of the project lead. The individual should display technical knowledge and scientific understanding of downstream purification of viruses, proteins, and plasmid DNA as well as having knowledge of process development at both small and large process scales
