Scientist/Senior Scientist, DMPK

Research | Berkeley, CA | Full Time

Job Description

Plexxikon, a member of the Daiichi Sankyo Group, is a leader in the discovery and development of novel, small molecule pharmaceuticals. The company utilizes its proprietary discovery platform to successfully develop a portfolio of competitively differentiated clinical and preclinical stage compounds in a number of therapeutic areas. Plexxikon’s first marketed drug, Zelboraf™ (vemurafenib) was the first precision medicine to be approved for the treatment of BRAF-mutant metastatic melanoma.  Plexxikon's demonstrated capability in discovery and early development uniquely positions the company to develop multiple commercial franchises for different therapeutic indications, and to create significant value for Plexxikon, Daiichi Sankyo and its collaborators.  Plexxikon's novel discovery approach, combined with experienced management and scientific teams, a broad network of scientific and clinical experts, and partnerships supporting later stage development, have been key drivers of the company's success since it began operations in 2001.  Plexxikon is a small business with approximately 65 employees based in Berkeley, California.
