Senior Toxicologist in Reproductive Toxicology & Epidemiology – Office of Environmental Health Hazard Assessment

California’s Office of Environmental Health Hazard Assessment (OEHHA) is seeking to hire a Senior Toxicologist with experience evaluating adverse effects on reproduction and development.


OEHHA conducts cutting-edge work to protect and enhance public health and the environment through the scientific evaluation of risks posed by hazardous substances. These evaluations are frequently the subject of statewide, national and even international interest, and are used by various regulatory programs in California.


Job Duties

The Senior Toxicologist will provide expert scientific oversight and supervision of a team responsible for providing technical support for listing chemicals as causing reproductive toxicity under Proposition 65, developing guidelines for assessing risks of exposure to chemicals that cause reproductive toxicity, and conducting dose-response and exposure assessment. Specifically, the duties of the Senior Toxicologist include:

  • Supervising reproductive/developmental hazard identification and hazard assessment activities, including directing the analysis by technical staff of scientific studies providing evidence on reproductive/developmental hazards.
  • Directing the preparation of technical documents summarizing the findings from epidemiologic studies, animal studies, and other relevant studies (e.g., pharmacokinetics, mechanisms) on chemicals.
  • Developing or reviewing the most complicated issues related to reproductive/ developmental hazard identification to ensure that scientific data and uncertainties are appropriately characterized.
  • Directing the assessment by technical staff of reproductive/developmental risks from exposures to environmental agents in the diet, air, water, home and workplace, and directing the evaluation of exposure sources, pathways, and levels by technical staff.
  • Providing toxicological expertise in the development and implementation of new methodologies in dose-response and exposure assessment.
  • Supervising the development of white papers on reproductive/developmental risk methodology and guidance.
