Open Positions: Senior Specialist, Payroll and Equity Plan Administration

Arvinas is a clinical-stage biopharmaceutical company focused on developing new small molecules ‒ known as PROTAC® (PROteolysis Targeting Chimera) protein degraders ‒ aimed at degrading disease-causing cellular proteins via proteolysis. Based on innovative research conducted at Yale University by Dr. Craig Crews, Founder and Chief Scientific Advisor, the company is translating natural protein degradation approaches into novel drugs for the treatment of cancer and other diseases. Our proprietary PROTAC®-based drug paradigm induces protein degradation, rather than protein inhibition, using the ubiquitin proteasome system and offers the advantage of potentially targeting “undruggable” as well as “druggable” elements of the proteome. This greatly expands the ability to create drugs for many new, previously unapproachable targets. For more information, visit
