What are the responsibilities and job description for the Sr. Scientist - Oncology Research position at CHEManager International?
About Leona
LeonaBio, Inc., headquartered in the Seattle, Washington area, is a clinical-stage biopharmaceutical company dedicated to the development of novel therapeutics for high unmet medical needs, including amyotrophic lateral sclerosis (ALS) and treatment-resistant metastatic breast cancer, with the goal of improving patients' lives. Our lead drug candidates, lasofoxifene and ATH-1105, are novel, small molecule therapies with the potential to address devastating diseases where current treatment options are limited or ineffective. With a strong commitment to scientific excellence and patient-centered innovation, we are dedicated to developing meaningful new therapies for those who need them most.
Position Overview
We are seeking a highly motivated Senior Scientist to lead and execute laboratory research supporting oncology drug development programs.
This role will focus on advancing our understanding of tumor biology and drug mechanisms of action, with an emphasis on generating data that informs translational and clinical development.
The ideal candidate brings deep expertise in oncology research and has experience or interest in immuno-oncology and tumor microenvironment biology, as well as a strong foundation in mechanisms of resistance and cell signaling pathways.
