Flow Cytometry Cell Sorter Jobs (NOW HIRING)

Your work will center on independently accomplishing single-cell isolation, small-scale viral packaging, high-throughput screening, and evaluating clone productivity and product quality to deliver stable and top-performing clones supporting AstraZeneca's emerging Cell Therapy portfolio. This position is based in Gaithersburg, MD.

Key Responsibilities:

• Cell Line Development & Viral Packaging: Perform mammalian CLD activities, including single-cell and mini-pool generation, small-scale viral vector packaging and high throughput titration, and clone selection to achieve robust viral productivity for upstream processes.

• High-Throughput Screening & Analytics Interface: Establish efficient, scalable workflows for rapid cell characterization and clone evaluation, and high-throughput titer screening; partner with analytical and process development teams to link clone selection choices to critical quality attributes using molecular/cell analytics (e.g., flow cytometry, qPCR/ddPCR, ELISA, titering assays).

• Cell line engineering: lead and implement cell line engineering to improve cell line performance, including LVV packaging efficiency, vector quality, genetic stability and overall robustness

• Data Analysis & Collaboration: Analyze and interpret complex datasets, maintain accurate experimental documentation, and collaborate with upstream Process Development and Analytical teams to support smooth process handoffs.

Qualifications:

• Education: PhD degree (or equivalent to 2-5 yoe) or Master's degree (or equivalent to 5-8 yoe) in Cell Biology, Molecular Biology, Bioengineering, Virology, or a related scientific field.

• BS+8-10 yoe / MS+3-4 yoe / PhD+0-2 yoe

Core Technical Expertise:

• Extensive, hands-on experience in mammalian CLD, viral vector packaging, and clone screening, with a strong emphasis on cultivating and optimizing HEK293 based host cells in suspension culture for high-yield Lentiviral vector production.

• Proficiency in single-cell isolation using cell sorter, advanced imaging systems, and clone characterization via flow cytometry.

• Experience with high-throughput titration assays and utilizing, maintaining, and troubleshooting automated liquid handling and high-throughput screening platforms.

• Experience with stable genetic modification of mammalian cells using approaches such as CRISPR/cas9

Desirable Experience:

• Experience in monoclonality validation and expanding stable master cell lines.

• Hands-on experience in virus/vector engineering for host cell line optimization or vector performance improvement.

• Background in viral vector biology, cell and gene therapy within the pharmaceutical industry, supporting vector design/engineering for maximized titers, quality and overall manufacturability.

• Viral vector stable producer cell line development

Core Competencies: Effective interpersonal skills, meticulous attention to detail, and independent troubleshooting capabilities and in a fast-paced laboratory environment.
