Toxicologist Positions in the California EPA and the Department of Pesticide Regulation

The California EPA Office of Environmental Health Hazard Assessment and the Department of Pesticide Regulation (DPR) are searching for candidates to fill multiple positions at the two agencies.  The DPR is searching for a Supervising Toxicologist (Human Health Assessment Branch Chief) and an Associate Toxicologist.  Both are located primarily in Sacramento, California and have an application deadline of October 15 and 30. The CalEPA Office of Environmental Health Hazard Assessment is also searching for a Senior Toxicologist (Chief of the Cancer Toxicology and Epidemiology Section) and several Cancer Toxicologists. The location for these is more flexible and applications will be accepted until the positions are filled.  More information on these positions can be on the CalCareers Website using the keyword toxicologist. 

I might mention that we have numerous alumni working at these two agencies and they seem to be content with their positions and opportunities.
