Job Description

The Staff Scientist in this position is expected to possess a clear understanding of the principles involved in various chromatography, Tangential Flow Filtration, and Formulation methods and have experience in developing downstream process schemes. This position involves development of scale-up procedures for protein and viral based cultures, optimization of procedures for optimal growth and productivity, and modification of existing procedures according to the federal regulations for making protein products suitable for human injection.

The successful candidate is expected to carry out the work independently with strict adherence to cGMP compliance and to overcome challenges in meeting all regulatory requirements for making a safe product while maintaining the structural integrity and biological function of the protein. This position is expected to provide training and leadership to technicians in the all areas of downstream production including chromatography methods, Tangential Flow Filtration principles, and Design of Experiment (DOE) procedures. It is also necessary to interact with other departments involved in GMP manufacturing for the production planning, product testing and quality assurance for product release. Previous experience in a CMO or CRO is a plus.


The main responsibilities will include but are not limited to:
• Develop robust, high-yield and scalable purification process (recombinant protein and Virus like Particles) for Vaccine Development and cGMP production of Phase I/II candidates.
• Develop, optimize and scale-up protein purification methods to meet cGMP and Regulatory Compliance using Design of Experiment (DOE) methods.
• Lead efforts to evaluate different resins, filters, and analytical methods pertinent to purification development activities.
• Perform experiments using AKTA series Chromatography skids, TFF systems, and industry standard Harvest methods scale.
