About the position Legend Biotech is seeking a Principal Scientist, Clinical Biomarker, Immunology & Immuno-Oncology (Hematology) as part of the Early Drug Development team based in Somerset, NJ. We are seeking a highly motivated and innovative Principal Scientist to join our immunology and immuno-oncology (IO) clinical biomarker projects, with a dedicated focus on hematological malignancies. In this role, you will drive the clinical translational understanding of novel therapy in hematology. You will serve as the biology lead on cross-functional project teams, drive MOA of novel cell therapy and clinical biomarker strategy. Responsibilities • Design, execute, and analysis results from clinical studies to investigate the mechanisms of action for novel IO targets in hematological indications (e.g., AML, DLBCL, Multiple Myeloma). • Bridge discovery and clinical development by utilizing primary human samples and clinical datasets to validate targets and understand the immune microenvironment in hematology. • Oversee the generation and interpretation of high-dimensional molecular and cellular data. • Leverage advanced single-cell technologies (e.g., scRNA-seq) to deeply profile immune cell compartments, particularly T-cell states and exhaustion markers, to inform patient stratification and biomarker hypotheses. • Partner closely with other functional teams for better understanding of MOA and fundamental immunology. Requirements • Ph.D. in Immunology, Immuno-Oncology, Cellular Biology, or a closely related discipline, can initiate and lead data driven MOA studies. • A minimum of 5-8+ years of post-doctoral and/or industry experience in biotech or pharma, with a proven track record of advancing IO programs. • Deep understanding of immunology, particularly T cell biology highly desirable. • Deep biological understanding of hematological malignancies and the unique tumor immune microenvironment of the blood and bone marrow. • Experience working with multiple dimensional data, extract biological insights from data highly desirable. • Exceptional written and verbal communication skills, with the ability to distill complex data into clear, actionable strategic decisions. Nice-to-haves • Experience with cell therapy a plus but not required.
