Senior Scientist, Viral Vector Process Development, Upstream

AstraZeneca is looking for a highly motivated and experienced Senior Scientist, Viral Vector Process Development (Upstream) . The candidate will play a critical role in building and leading a high-performing team that accelerates AstraZeneca’s emerging Cell Therapy modalities portfolio. You will design, execute, and optimize upstream Lentiviral Vector (LVV) processes with a primary focus on suspension bioreactor platforms at clinical and commercial scales. You will contribute hands-on to experimental design, process characterization, and scale-up/tech transfer activities from research through IND enabling , partnering closely with Research, Analytical Development, CMC, Regulatory, Manufacturing, Quality, and external CDMOs. This position is based in Gaithersburg, MD. Key Responsibilities Upstream Process Development : Plan and perform experiments to develop and optimize LVV upstream processes for suspension cell culture (transient or stable producer cell systems), targeting improvements in titer , quality, robustness, and cost. Bioreactor Operations & Scale Translation : Execute unit operations across seed, production, and harvest interfaces; support scale-up strategies from bench to pilot and clinical scales; develop and use scale-down models for characterization and comparability. Experimental Design & Data Analysis : Design DOE studies, identify CPPs/CMAs, analyze data, and propose control strategies; document results in protocols and reports; maintain fit for purpose knowledge records. Process Characterization & Control : Contribute to definition of design space, in-process controls, and operating ranges; trend process performance and drive troubleshooting, root cause analysis, and corrective actions. Tech Transfer & GMP Interface : Prepare technical transfer packages and support transfers to internal GMP sites and CDMOs; align process documentation with cGMP principles for late-stage readiness. Cross-Functional Collaboration : Work closely with Analytical Development on assay readiness and in process testing; partner with Manufacturing, Supply, and Quality to ensure operational feasibility and compliance. Operational Excellence : Apply Lean practices and digital tools for scheduling, data integrity, and reproducibility; track KPIs (titer, infectivity, impurity profiles, cycle time, right first time ) and recommend improvements. Qualifications Education : PhD in Bio logy , Virology, Biotechnology, or related field with 2–5 years of relevant industry experience; or MS with 5–8 years; or BS with 8–10 years. Title will be commensurate with qualifications and experience. Experience : Hands on experience developing suspension-based LVV upstream processes; familiarity with clinical/commercial scale considerations, process characterization, and technology transfer. Technical Skills : Proficiency in suspension cell culture, transfection/infection strategies, media/feed optimization, single use rocking-platform and stirred-tank bioreactors, and upstream–harvest interfaces; working knowledge of statistical DOE and data analytics tools. GMP Readiness : Experience supporting cGMP interfaces (documentation, change control, sampling plans) and contributing to CMC sections or technical responses is a plus. Communication & Teamwork : Strong written and verbal communication skills; ability to work effectively in cross functional , matrixed teams; demonstrated problem solving and troubleshooting capability. Tools & Automation : Experience with single use systems, process automation/PAT, and digital lab systems (ELN/LIMS) preferred. Preferred Qualifications Demonstrated success scaling suspension LVV processes to pilot/clinical scales and sustaining performance via monitoring and continuous improvement. Experience linking upstream parameters to analytical outcomes (titer, infectivity/potency, residuals/impurities) to guide process decisions. Contributions to regulatory filings (data tables, process descriptions) and participation in tech transfer to CDMOs or internal GMP sites. Experience implementing Lean/continuous improvement and robust documentation/knowledge management in PD labs. The annual base pay for this position ranges from $ 108,473.60 - $162,710.40 .
