Full Job Description
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 scalable Lentiviral Vector (LVV) downstream purification processes with a primary focus on clinical and commercial scales. You will contribute hands-on to experimental design, process characterization, and scale-up/tech transfer activities from research through INDenabling, partnering closely with Research, Analytical Development, CMC, Regulatory, Manufacturing, Quality, and external CDMOs. This position is based in Gaithersburg, MD.

Key Responsibilities

  • Downstream Process Development: Plan and perform experiments to develop scalable, cost-effective LVV purification processes for ex vivo and in vivo applications, targeting yield, purity, potency, and consistency.


  • Unit Operations Execution: Execute and optimize clarification, chromatography, UF/DF/TFF, sterile filtration, and formulation/fill-related steps; define phase-appropriate in-process controls and operating ranges.


  • Process Characterization & Data Analysis: Design and analyze studies (including DOE) to identify CPPs/CMAs, establish design space, and justify control strategies; trend performance, conduct troubleshooting and root cause analysis, and recommend corrective actions.


  • Scale-Up, Scale-Down & Tech Transfer Support: Develop representative scale-down models; support scale-up to pilot, clinical, and commercial-relevant equipment; prepare technical transfer documents and assist transfers to internal GMP sites and CDMOs.


  • Novel Technologies & Continuous Improvement: Evaluate and implement next-generation purification technologies and consumables to improve efficiency, robustness, and product quality; contribute to continuous improvement initiatives.


  • Documentation & Compliance: Author high-quality protocols, reports, batch records, and development summaries; support drafting of CMC content for regulatory submissions (e.g., IND) and align practices with cGMP and Quality systems expectations.


  • Cross-Functional Collaboration: Partner with upstream PD and Analytical Development to link process parameters with product quality attributes (e.g., titer, infectivity/potency, residuals/impurities); collaborate with Manufacturing and Quality on operational feasibility and compliance.


Qualifications

  • Education: Ph.D. in Chemical Engineering, Biochemical Engineering, Biotechnology, or related field with 1+ years of industry experience; OR M.S. with 4+ years; OR B.S. with 5+ years of hands-on industry experience.


  • Experience: Hands-on downstream process development for LVV (preferred) or other viral vectors/biologics; familiarity with clinical/commercial scale considerations and tech transfer.


  • Technical Expertise: Practical proficiency in clarification, chromatography, UF/DF/TFF, sterile filtration, and formulation; understanding of viral vector-specific impurity profiles (host cell proteins/DNA, process residuals) and strategies to control them.


  • Data & Risk Tools: Working knowledge of statistical analysis and DOE; familiarity with QbD principles, risk assessments (e.g., FMEA), and process justification.


  • GMP & Regulatory: Understanding of cGMP and Quality systems; familiarity with FDA/EMA guidance relevant to gene and cell therapy; experience contributing to CMC sections of regulatory filings is a plus.


  • Communication & Collaboration: Strong written and verbal communication; ability to work effectively in cross-functional, matrixed teams; demonstrated problem-solving and troubleshooting skills.


Preferred Qualifications

  • Experience scaling LVV or other viral vector/biologic purification processes from preclinical to clinical/commercial-relevant equipment and consumables.


  • Experience supporting tech transfer and implementation at internal sites and CDMOs.


  • Exposure to PAT/digital tools for process monitoring and data integrity; experience with knowledge management systems.


  • Demonstrated innovation in evaluating/implementing next-generation purification technologies.


The annual base pay for this position ranges from $108,473.60 - $162,710.40. Hourly and salaried non-exempt employees will also be paid overtime pay when working qualifying overtime hours. Base pay offered may vary depending on multiple individualized factors, including market location, job-related knowledge, skills, and experience.
