Associate Scientist – Drug Formulation
About The Position
At Insmed, every moment and every patient counts — and so does every person who joins in. As a global biopharmaceutical company dedicated to transforming the lives of patients with serious and rare diseases, you’ll be part of a community that prioritizes the human experience, celebrates curiosity, and values every person’s contributions to meaningful progress. That commitment has earned us recognition as Science magazine’s No. 1 Top Employer for five consecutive years, certification as a Great Place to Work® in the U.S., and a place on The Sunday Times Best Places to Work list in the UK. For patients, for each other, and for the future of science, we’re in. Are you? About the Role: We’re looking for an Associate Scientist on the Drug Formulation team to help us expand what’s possible for patients with serious diseases. Reporting to the Senior Scientist, you’ll focus on the development, optimization, and characterization of nanoparticle (NP)-based drug delivery systems. You will be part of a multidisciplinary team engaged in non-viral vehicle formulation and characterization, supporting platform build and project-level activities.
