Senior Associate Scientist-Scientist - Cell Biology and Immunology

Senior Associate Scientist / Scientist – Cell Biology & Immunology

Prellis Biologics is a dynamic startup revolutionizing the field of immunology. We are developing next‑generation technologies to harness the full potential of the immune system, driving innovation in therapeutic development.

We are seeking a passionate and skilled immunologist to help advance our pioneering in‑vitro immune system platform. In this role, you will collaborate with a multidisciplinary team to engineer lymph node organoids, design and execute high‑impact assays, and contribute to the development of immune processes and antibody engineering strategies.

• Design, execute, and analyze complex cell‑based experiments aligned with research objectives.
• Isolate, culture, and maintain primary and established immune cell lines using aseptic techniques.
• Perform multiparameter flow cytometry and cell sorting for immune profiling and functional assays.
• Utilize innovative approaches to stimulate and characterize immune cell responses.
• Contribute scientific insight to the design and development of in‑vitro immune processes and antibody generation strategies.
• Maintain a hands‑on presence in the lab (60–80% of the time) in a fast‑paced research environment.
• Develop, optimize, and run immune assays, including ELISA and other protein quantification methods.
• Perform basic protein assays such as Western blotting and protein quantification.
• Ensure all experimental work complies with established protocols, SOPs, and regulatory standards.
• Maintain accurate, detailed, and traceable experimental records.
• Analyze, interpret, and present findings at internal meetings and project reviews.
• Support troubleshooting, protocol refinement, and continuous improvement initiatives.
• Collaborate with cross‑functional teams to align project goals and share expertise.

• M.S. or Ph.D. in Immunology, Cell Biology, Biotechnology, or a related discipline.
• 5+ years of laboratory experience in immunology or cell biology (industry experience preferred).
• Strong understanding of adaptive immunity, particularly B and T cell biology.
• Knowledge of cell–cell interactions and ligand–receptor signaling pathways.
• Proficiency in mammalian cell culture, immune cell isolation, and maintenance.
• Demonstrated expertise in flow cytometry, including panel design, staining, acquisition, and analysis.
• Experience in immune functional assays, ELISA, and protein analysis techniques.
• Familiarity with laboratory compliance standards, SOPs, and documentation best practices.
• Strong organizational skills, attention to detail, and ability to work independently or collaboratively.
• Effective verbal and written communication skills for data reporting and documentation.
• Expertise in experimental design, data interpretation, and complex immunological data analysis.
• Proficiency in primary cell isolation, culture, and in‑vitro assay development.

• Knowledge of immune tolerance, vaccine development, or systems immunology.
• Experience in project management.
• Background in protein or sequence bioinformatics.
• Familiarity with molecular biology techniques.
• Experience implementing lab systems or high‑throughput screening platforms.
• Skilled in data analysis tools such as Flow Jo and Graph Pad Prism.
• Prior experience in drug discovery, vaccine and/or antibody development.

• Detail‑oriented with a strong sense of responsibility for compliance and documentation.
• Proactive, collaborative, and adaptable in a dynamic research setting.
• Committed to scientific rigor and continuous professional development.
