What does a Full Time Downstream Process Development Scientist do?

A Full Time Downstream Process Development Scientist is responsible for designing, optimizing, and scaling up processes that purify biological products such as proteins, antibodies, or vaccines after they are produced in cells or microbes. This role involves developing and improving techniques like filtration, chromatography, and centrifugation to ensure high purity and yield of the final product. The scientist also conducts experiments, analyzes data, and collaborates with cross-functional teams to transfer processes from the lab to manufacturing. Their work is critical for producing safe and effective biopharmaceuticals on a large scale.

What is the difference between Full Time Downstream Process Development Scientist vs Downstream Process Engineer?

AspectFull Time Downstream Process Development Scientist
Primary FocusDesigning, optimizing, and developing downstream purification processes for biopharmaceuticals
Required CredentialsBachelor's or Master's in Biotechnology, Biochemistry, or related field; experience in process development
Work EnvironmentLaboratories, R&D settings, collaborative teams in biotech or pharma companies
Typical ResponsibilitiesProcess scale-up, method validation, troubleshooting, documentation

While both roles involve downstream bioprocessing, the Full Time Downstream Process Development Scientist focuses on process development and optimization, whereas the Downstream Process Engineer typically handles process implementation and manufacturing support. The scientist role emphasizes research and development, while the engineer role is more operational. Candidates often hold similar degrees and certifications, but their daily tasks and focus areas differ.

What are some typical challenges faced by a Downstream Process Development Scientist, and how can they be addressed?

Downstream Process Development Scientists often encounter challenges such as optimizing protein purification processes to achieve high yield and purity, troubleshooting unexpected impurities, and scaling up processes from laboratory to manufacturing scale. These tasks require strong problem-solving skills, meticulous attention to detail, and effective collaboration with upstream teams, analytical scientists, and manufacturing staff. Addressing these challenges involves staying current with new purification technologies, maintaining robust documentation, and participating in cross-functional meetings to ensure seamless process integration and regulatory compliance.

What are the key skills and qualifications needed to thrive as a Full Time Downstream Process Development Scientist, and why are they important?

To thrive as a Full Time Downstream Process Development Scientist, you need a strong background in biochemical engineering, protein purification, and analytical techniques, typically supported by a degree in biochemistry, biotechnology, or a related field. Proficiency with chromatography systems (e.g., HPLC, FPLC), filtration technologies, and knowledge of regulatory and quality systems like GMP is essential. Strong problem-solving abilities, teamwork, and effective communication skills help you collaborate with cross-functional teams and troubleshoot process challenges. These skills are crucial for developing robust purification processes that ensure product quality, regulatory compliance, and efficient production in biopharmaceutical environments.

Job description

AstraZeneca is looking for a highly motivated and experienced Senior Scientist, Viral Vector Process Development (Downstream). 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.
