Job Description

We are looking for an experienced Process Development Scientist with specific expertise in protein purification and recovery. This individual should have a proven track record developing scalable purification processes and managing talented Associate-level direct reports. Successful candidates will be part of a growing interdisciplinary, dynamic and enthusiastic team responsible for further expanding company s biotherapeutic project portfolio and maximizing core technologies for the design, optimization and development of transformational protein therapeutics. This individual will also use his/her experience and critical thinking skills to contribute to building an expanding process development group that can meet the demands of the organization. Strong experience in developing purification processes ready for transfer to CDMOs and overseeing scale up and manufacturing of clinical grade drug substance is required.


The Process Development Scientist will be responsible for:

Development of purification processes for newly evolved enzymes expressed in a variety of microbial and mammalian hosts.

Troubleshoot and adapt analytical methods to quantify yield, activity, and purity at various stages of the manufacturing process

Characterization of the physicochemical properties of newly evolved enzymes such as pI, molecular size, pH and temperature stability to provide relevant information purification development.

Development of unit operations at the bench -scale (10L) such as, centrifugation, homogenization, precipitation, ultra-filtration, depth filtration and chromatography.

Production of purified enzymes for animal studies, reference standards, and preliminary stability studies.

Working within multidisciplinary project teams to design and execute process development campaigns, interpreting data, and working with other team members to integrate results into process designs and overall project plans.

Troubleshoot and maintain analytical and process equipment.

Identify and evaluate new technologies for downstream processing and analysis.

Authoring and review of equipment and process SOPs.
