  • You will become a technical subject matter expert on fermentation of diverse anaerobic organisms, and oversee and implement new processes, equipment selection, vendor interactions, and technology transfer.
  • You will be a terrific mentor and teammate for our associates and scientists, and establish productive partnerships with Bioprocess & Analytical Development to leverage existing in-house expertise in support of Research Biobanking operations. You will also interface with Molecular Technologies and other teams to improve qualification processes and data management.

  • Several years of demonstrated leadership with skills to ensure alignment and engagement of your team with Microbiology and company goals, and to champion personal development and continuous improvement.
  • The ability to deliver products to customers, in particular within a preclinical drug development environment (with associated quality, documentation, and data tracking rigor).
