The Biologics Upstream Process Development and Manufacturing group is responsible for developing recombinant protein production processes, with a great emphasis on product quality, and the subsequent technology transfer to cGMP Manufacturing. Additionally, the upstream group supports the protein expression needs for multiple early stage research programs.
The candidate hired for this position will employ and create new analytical methods, including HPLC based approaches, to track protein quality between microbial fermentations and within microbial fermentation time courses. The candidate will also perform small scale inclusion body extractions, refolding and chromatography to verify the quality of recombinantly expressed proteins. She or he will write development and qualification reports for upstream in-process methods that are to be used in GMP manufacturing. The candidate will participate in technology transfer of upstream processes to partners or CMOs. Additionally, the candidate will review and/or authors the CMC sections of regulatory filing documents. The ideal candidate will demonstrate an understanding in microbial fermentation and an expertise in both protein analytical techniques, including HPLC method development, and small scale purification, to analyze and characterize the quality of the microbial expressed proteins.
Essential Duties and Responsibilities:
Development of HPLC based and other analytical methods for analysis of fermentation samples
Small scale primary recovery including homogenization, inclusion bodies isolation, protein refolding, tangential flow filtration and chromatography using AKTA systems
Integration of protein yield and quality analytical data with fermentation trend data to form hypotheses towards improved processes
Support of upstream process scale-up, tech transfer, and CMO manufacturing support
Supports efforts to identify and minimized host cell protein impurities carried thru the protein production process
Documents results and developed process in Internal Reports, Qualification Reports, and/or Technology transfer documents.
When necessary, supports CRO/CMO manufacturing through process demonstration, person in plant (PIP) coverage, and troubleshoots manufacturing issues
Work efficiently, collaboratively, and cross-functionally toward project timelines and goals
Attention to detail and ability to keep detailed written records in lab notebook
Independently design, execute, and interpret laboratory experiments to answer scientific questions
Forward-thinking to lead and contribute to scientific or technical discussions
Clear and presentations of results and/ or proposed experiments
Must possess a positive, can-do attitude and demonstrate creative, problem-solving skills
Flexibility and ability to adapt to quickly changing priorities
Mentor and train junior scientists
