Job Description The Biologics CMC Development team at AbbVie has a distinguished history of advancing complex biologic therapies through all phases of development, from discovery to licensure. Our state-of-the-art facility in South San Francisco provides comprehensive CMC capabilities and a highly collaborative environment focused on innovative drug substance development. You will join a team that has enabled 20 IND submissions and two successful BLAs. We are seeking a highly motivated Senior Scientist I to join the Purification Development team. This individual will apply mechanistic modeling and/or advanced AI / machine learning (ML) strategies to the development, optimization, and scale-up of robust, phase-appropriate purification processes for biotherapeutic candidates. The ideal candidate will leverage historical and incoming process data to drive process understanding, forecast outcomes, and accelerate project timelines. Key Responsibilities: Design, implement, and validate mechanistic models and/or AI/ML (e.g., for process performance prediction, process understanding, and workflow optimization) using historical and real-time data from lab scale purification development and pilot/GMP manufacturing. Actively seek out opportunities to optimize current platform or enhance our understanding of purification unit operations using advanced models and wet lab experiments. Contribute to or drive mechanistic modeling efforts for chromatography and/or membrane separations, supporting process control and troubleshooting. Execute wet lab validation experiments with detailed documentation practices. Collaborate closely with cross-functional teams to meet project deliverables and timelines. Analyze complex datasets, utilize advanced data visualization tools, and communicate data-driven recommendations to technical teams. Proactively monitor relevant scientific literature and integrate innovative bioprocess advances. Write technical publications, reports, presentations, and regulatory filings; publish research in peer-reviewed journals and present work at scientific conferences. Mentor junior staff and uphold best practices in documentation, safety, and GxP compliance where applicable. Qualifications BS, MS, or PhD in Computer Science, Statistics, Applied Mathematics, Bioinformatics, Machine Learning, Computational Biology, Data Science, Chemical Engineering, Bioengineering, or a related field, with typically 10 years (BS), 8 years (MS), or 0 years (PhD) of industry or research experience as either: an expert in mechanistic modeling for protein separations with some demonstrated proficiency in AI/ML approaches.
