About The Position

As a Medical Director in Immunology, you will play a pivotal role in advancing clinical development programs for immune-mediated diseases — from study design through execution, data interpretation, and regulatory documentation. In this role, you will serve as a key clinical voice within global cross-functional teams, contributing to the scientific rigor and strategic direction of immunology assets that have the potential to address meaningful unmet patient needs. You will provide day-to-day medical oversight for assigned clinical studies, including safety data review, protocol deviation assessment, and interpretation of accumulating efficacy and biomarker data. Working closely with experienced medical and functional leaders, you will contribute to clinical development planning, support governance discussions with well-reasoned medical analyses, and help shape evidence generation strategies across assigned indications. You will also contribute to regulatory documents and health authority interactions, ensuring all deliverables are scientifically sound, compliant, and inspection-ready. This position offers a clear pathway toward broader program-level medical leadership, with increasing ownership of study strategy and cross-functional decision support as you grow within the organization.
