  • Lead scientific research projects and / or mentor other scientists.
  • Conduct and document process optimization studies [for e.g., design of experiments (DoE) and quality by design (QbD)] and apply changes to the modified route.
  • Maintain a current and accurate laboratory notebook that documents all experimental results.
  • Comply with all safety, health, and environmental requirements.


  • Degree Requirements:
    • Ph.D., Organic Chemistry with 0-6 years of experience in the pharmaceutical development industry
