Senior Director, Field Medical

Using living cells to treat – and sometimes even cure – cancer is one of the most dramatic advances in modern medicine. Patients with hematologic malignancies have been successfully treated with cell therapies. However, these profound results have not yet been achieved in patients with solid tumors, representing approximately 90% of all cancers. And for patients with hematologic malignancies, there is a need for next-generation cell therapies that can deliver increased response rates and longer duration of response.  We are a clinical-stage company advancing a pipeline of next-generation CAR T-cell therapies for patients with solid tumors or hematologic malignancies. Lyell’s product candidates are enhanced with novel technology designed to generate T cells that resist exhaustion and have qualities of durable stemness in order to drive durable tumor cytotoxicity and achieve consistent and long-lasting clinical response. We were founded by cell therapy pioneers whose decades of research elevated the broader understanding of T-cell biology and its interaction with cancer. In our quest to advance next-generation CAR T-cell therapies, we have built a fully integrated company capable of discovering new technologies, translating science into therapies, manufacturing cell therapy products, and clinically evaluating them in patients. Our culture is based on Science, Respect, Collaboration, and Courage and reflects who we are, the environment we create, and our mission's urgency.     The Senior Director, Field Medical will serve as the architect and operational leader of Lyell’s inaugural U.S. Field Medical function. Reporting directly to the SVP, Medical Affairs, this leader will be responsible for designing the infrastructure, governance, and strategic direction of the field team.

This role requires a "builder" mindset to establish foundational systems (CRM, SOPs, KPIs) and recruit a high-performing team of Medical Science Liaisons (MSLs). The Senior Director will ensure the field team effectively supports the pivotal PiNACLE studies in lymphoma, the LYL273 program in metastatic colorectal cancer (mCRC), and future solid tumor pipeline assets.
