Senior Scientist/Principal Scientist – Cell Biology/Assay Development

About Us: Entact Bio is a preclinical stage biotechnology company developing a new class of drugs that enhance the function of beneficial proteins. Launched by a founding team deeply rooted in deubiquitinase (DUB) biochemistry, chemical biology, disease biology, and small-molecule drug development, Entact has designed its proprietary Encompass™ platform to create enhancement-targeting chimeric (ENTAC™) medicines. ENTACs harness the ability of DUBs to regulate proteins. By leveraging this natural cellular mechanism to enhance protein function, Entact is expanding the universe of treatable diseases.
