Job Description AbbVie Biotherapeutics and Genetic Medicine is an integrated, global discovery organization responsible for biotherapeutics drug research across disease areas including immunology, oncology, neuroscience, and eye care. Our scope includes the discovery of innovative biologic medicines from the early exploratory stage and their support through clinical development. We are growing a world-class team of scientists and leaders who will drive the discovery and advancement of innovative biologic-based therapies. Careers in AbbVie Biotherapeutics and Genetic Medicine provide unique opportunities to work with cross-functional teams that drive exceptional science and deliver innovative medicines to patients. We are looking for diverse candidates with strong scientific and leadership experience to join the team and can offer exciting and rewarding career opportunities for these candidates. The Biotherapeutics Production group at AbbVie is seeking an experienced bispecifics/multi-specifics cell line and protein expression scientist to join a fast paced, high throughput, large scale mammalian expression group. The Biotherapeutics mammalian expression group supports medium to large scale (1 to 100L) expression of bispecific/multi-specific biologics in support of AbbVie’s worldwide drug discovery efforts. Key Responsibilities: + Expression of bispecifics and other novel multi-specific biologics formats to support therapeutic area drug discovery projects. + Transient and stable CHO expression vector design (including complex 3-chain and 4-chain multi-specific molecules), + Generation of stable CHO cell lines using 2 or more vectors and multiple selection strategies to optimize chain pairing of 3- and 4-chain molecules. + Transient protein expression of 3- and 4-chain molecules in CHO cells, and process optimization to determine optimal chain ratio. + Maintenance of stable CHO pools and cell lines- including thaw, culture, expression and cryopreservation. + Process development and optimization for batch and fed-batch Wave bioreactor and shake flask expressions of transient and stable CHO cell lines expressing multi-specifics. + Purification and biophysical characterization of analytical scale expression samples, using analytical HPLC to evaluate titer, % monomer, and chain pairing efficiency. + Work independently on the design, execution, and interpretation of experimental results. + Analyze, document, and report data concisely and rigorously. Qualifications Qualifications: + Bachelors or Masters in biology, chemistry, biochemistry or related field with typically 5-7+ (BS) or 2-5+ (MS) years of experience. + Hands-on experience with cell culture and transient protein expression of bi-specifics and multi-specifics in CHO cells. + Prior experience in transient and stable vector design and generation of stable CHO cell lines expressing complex 3- and 4-chain multi-specific molecules. + Prior experience with analytical characterization of multi-specifics desirable. + Prior experience in mammalian expression using Wave bioreactors desirable. + Experience in process development and process optimization. + Demonstrated proficiency in overcoming problems (i.e. poor chain pairing, low expression, aggregation, glycosylation) with challenging therapeutic multi-specific proteins desirable. Position will be filled at level commensurate with extent of education, experience, and accomplishment - Scientist I or Scientist II.
