Scientist, Cellular Immunology and Inflammation

Position Summary

Prologue Medicines is seeking a highly motivated, focused, and creative Scientist, Cellular Immunology and Inflammation to join our Research and Discovery team. You will advance therapeutic discovery programs by designing, developing and running cellular immunology and inflammation studies that support target validation, biological characterization and mechanism-of-action investigations. This is a team-based, collaborative role in a matrixed environment.

Key Responsibilities

• Independently design, execute and analyze in vitro and ex vivo cellular immunology and inflammation experiments that support target validation, therapeutic discovery and mechanistic investigations.
• Develop, optimize and implement robust cell-based assays to evaluate immune cell activation, differentiation, proliferation, signaling, inflammatory responses and functional outputs.
• Apply multiparameter flow cytometry expertise, including panel design, staining optimization, data acquisition, analysis and cell sorting, to characterize immune cell populations and biological responses.
• Isolate, culture and manipulate primary human and/or animal immune cells, including innate and adaptive populations, using established techniques such as MACS and FACS.
• Design and execute phenotypic and mechanism-of-action studies to investigate immune and inflammatory pathways, validate therapeutic targets and test biological hypotheses.
• Apply complementary readouts to characterize cellular responses and assess therapeutic activity, including transcriptomic profiling and biomarker and cytokine assays.
• Critically analyze experimental data, troubleshoot assay performance and recommend follow-up experiments to inform discovery program decisions.
• Collaborate with cross-functional research teams to integrate cellular immunology findings into broader discovery and translational research strategies.
• Develop and maintain experimental protocols, assay documentation and laboratory best practices that ensure scientific rigor, reproducibility and data integrity.
• Present experimental findings, scientific interpretations and recommendations to cross-functional teams and leadership.
• Stay current with emerging scientific literature, technologies and methodologies in cellular immunology, inflammation and therapeutic discovery.

Required Qualifications

• PhD in Immunology, Cell Biology, Molecular Biology or a related biological discipline, or an M.Sc. with 6+ years of directly relevant experience in cellular immunology.
• Demonstrated hands-on expertise with patient-derived tissues and primary immune cells, including isolation, culture, stimulation, differentiation and functional characterization.
• Strong proficiency in multiparameter flow cytometry, including panel design, staining protocol optimization, data acquisition and analysis.
• Proven experience developing, optimizing and troubleshooting cell-based functional and mechanistic assays.
• Strong understanding of immune cell biology, immune and inflammatory signaling pathways, and the mechanisms underlying innate and adaptive immune responses.
• Experience with immunological and biomarker readouts performed in singleplex and multiplex formats, such as MSD, Luminex, ELISA, ELISpot, AlphaLISA and TR-FRET.
• Demonstrated ability to design experiments independently, critically evaluate results and translate scientific findings into actionable recommendations.
• Proficiency in quantitative data analysis and statistical interpretation, with experience using relevant scientific analysis tools (e.g., FlowJo, GraphPad Prism, R or Python).
• Excellent organizational, problem-solving, communication and presentation skills.
• Ability to work independently and collaborate effectively as part of team-based, matrixed, multidisciplinary research teams.

Preferred Qualifications

• Experience in biotechnology or pharmaceutical research supporting early-stage therapeutic discovery, target identification, validation and mechanism-of-action studies.
• Experience with bulk RNA-seq and, ideally, single-cell approaches (e.g., scRNA-seq, CITE-seq), plus qPCR and targeted expression panels.
• Familiarity with genomic analysis and bioinformatics (e.g., differential expression, pathway analysis), or the ability to partner effectively with computational biologists.
• Experience with mammalian cell transfection and genetic perturbation (e.g., CRISPR knockout or CRISPRi, siRNA, lentiviral or electroporation in primary cells).
• Familiarity with plate-based assay formats (96- and 384-well), assay miniaturization and robustness metrics, and laboratory automation.
• Experience developing new experimental workflows, establishing assay platforms or implementing innovative immunological technologies.
• Experience designing or contributing to in vivo immunology studies and integrating findings with in vitro and ex vivo results.
• Demonstrated scientific leadership, including mentoring junior scientists or research associates and contributing to research strategy.
