• Expression of novel multi-specific biologics formats to support therapeutic area drug discovery projects.
• Generation and screening of stable CHO cell lines with optimized attributes (i.e. titer, monomer, chain-pairing) using 2 or more vectors.
• Determine optimal chain ratio for 3- and 4-chain molecules in CHO cells using multiple selection strategies and process optimization.
• Process development and optimization for batch and fed-batch bioreactor and shake flask expressions of stable CHO cell lines expressing complex multi-chain molecules.
• Characterization of stable CHO line copy number and mRNA transcript levels using ddPCR and related molecular tools.
• Apply targeted integration technologies using screening workflows, including FACS-based single-cell sorting to generate mini pools.
• Implement and leverage automation platforms and high-throughput workflows to increase efficiency.
• Contribute to data digitization efforts, including electronic data capture, analysis, and reporting.
• Troubleshoot challenges related to expression, stability, glycosylation, aggregation, and chain pairing.
• 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.
• Handling stable CHO pools and cell lines including thaw, culture, expression and cryopreservation.

Position will be hired based on level of experience and education

• Bachelors or Master’s in biology, chemistry, biochemistry or related field with typically 5+ (BS) or 2+ (MS) years of experience.
• Hands-on experience with cell culture and expression of monoclonal antibodies, bi-specifics and multi-specifics in CHO cells lines including thaw, culture, expression and cryopreservation.
• Prior experience in generation of stable CHO cell lines expressing complex multi-specific molecules.
• Prior experience in process development, process optimization, and automation.
• Experience with analytical characterization of multi-specifics desirable.
• Experience with targeted integration, FACS, and ddPCR desirable.
• Demonstrated proficiency in vector design is desirable.
• Prior experience in mammalian expression using Wave bioreactors desirable.
• Demonstrated proficiency in overcoming problems (i.e. poor chain pairing, low expression, aggregation, glycosylation) with challenging therapeutic multi-specific proteins desirable.
