** Job Description
** We aspire to be the premier research-intensive biopharmaceutical company. We're at the forefront of research to deliver innovative health solutions that advance the prevention and treatment of diseases in people and animals. Join our Chemical Commercialization Technology (CCT) department, part of our manufacturing division, and be part of a highly collaborative environment that provides substantial technical responsibility and leadership of internal and external work.  

The Chemical Commercialization Technology (CCT) department, which is part of our Company's Manufacturing Division, is seeking self-motivated individuals who are looking for an opportunity to work in a highly collaborative environment that provides substantial technical responsibility and leadership of internal and external work.  The Senior Scientist, Engineering position leverages scientific/technical experience to develop safe and robust manufacturing processes through process characterization, technology transfer, validation, filing and supply support of late-stage projects in the small molecule pipeline.  

Given the significant role of biocatalysis and enzymes in the portfolio, the ideal candidate should have a specific expertise in microbial fermentation and downstream processing and is expected to draw on their expertise to optimize and fully characterize the enzyme manufacturing process control strategy across different scales.
The successful candidate will play a pivotal role in developing internal technical capabilities via mentoring junior staff and enhancing fermentation and downstream processing laboratory capabilities, in addition to supporting transfer of technologies to commercial manufacturing.  The candidate will provide scientific expertise by learning and utilizing Quality Risk Management methodologies and tools for statistical design of experiments. This role involves hands-on experimentation at the laboratory bench and kilo lab scales in addition to technology transfer to commercial manufacturing facilities.

The scientist will be expected to exhibit a mindset of safety and quality compliance, which will include following current Good Manufacturing Practices (cGMPs), and participating in risk assessments, deviation investigations, and Good Documentation Practices (GDPs).  ###
