About The Position

Alexion, AstraZeneca Rare Disease is seeking a full-time Associate Scientist to join our AAV manufacturing team supporting both upstream and downstream activities for AAV production. The role will execute and optimize process conditions, contribute to technology transfer, and drive continuous improvement with a strong focus on chromatographic purification, Tecan liquid handling systems, and data-driven decisions for production analytics. You will be responsible for: Downstream operations: Execute clarification, chromatography (affinity and IEX), TFF buffer exchange and concentration, and formulation with conditions aligned to outputs from Ambr250 through 50L, assist in DoE-driven optimization. Automation and high-throughput: Program, operate and troubleshoot Tecan platforms for sample prep, plate-based screening, fraction handling, buffer preparation, and in-process testing support integrated into upstream/downstream unit ops. Process Analytics and visualization: Use JMP to analyze and interpret production run data (multivariate analysis, control charts, variability analytics, regression/ANOVA, DoE modeling); build dashboards and reports to communicate insights and drive decisions. Coordinate and interpret in-process controls and CQAs (vg titer, capsid ratio, purity, HCP/residuals) in partnership with analytical teams, summarize data to inform scale-up decisions. Documentation and Compliance: Author and maintain SOPs, study protocols, batch records, and technical reports; ensure adherence to safety, data integrity, and Alexion/AZ quality standards. Continuous improvement: Identify opportunities to improve yield, robustness, and throughput across the Ambr250-50L scale range, contribute to platformization and digital/automation initiatives with a focus on implementation of AI. Upstream operations: Assist with upstream operations using bioreactors ranging from Ambr250 to 50L stir tanks, as needed.
