Senior Scientist, Analytical Development

Proteostasis Therapeutics, Inc. is an innovative biopharmaceutical company committed to the discovery and development of novel therapeutics that treat diseases caused by an imbalance in the proteostasis network, a set of pathways that control protein biosynthesis, folding, trafficking and clearance. Our initial therapeutic focus is on cystic fibrosis, or CF, which is caused by defects in the cystic fibrosis transmembrane conductance regulator, or CFTR, protein and insufficient CFTR protein function. CF is an orphan disease that affects an estimated 70,000 to 100,000 patients worldwide, with the vast majority of affected individuals in the United States, Canada, Europe and Australia. CF is the most common fatal inherited disease in Caucasians, and there is presently no cure.

We seek to hire talented people and to create an environment that facilitates continued professional growth. The extensive and ongoing work with our founders and collaborators adds an outward-looking, collaborative aspect to the company’s culture. This blend of internal and external talent, combined with cutting-edge science and an innovative business model, make Proteostasis Therapeutics an exceptional place to work.
