Director, Clinical Science

Posted 8/14/2026 · last confirmed live 8/26/2026

  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.   This role can be based out of either our Seattle, WA or South San Francisco, CA offices. The Director, Clinical Science is a critical scientific partner in the clinical development of Lyell’s potential cell therapies. Working in close partnership with medical monitors and cross-functional study teams, this role supports the design, execution, and oversight of clinical trials — ensuring adherence to regulatory standards, Good Clinical Practice (GCP), and scientific rigor. The role will focus initially on supporting study medical monitoring for the pivotal PiNACLE and PiNACLE-H2H studies, with the agility to support additional programs as the organization’s needs evolve. Reporting to the Vice President, Clinical Development, this is a hands-on, collaborative role centered on partnering, support, and cross-functional execution. KEY ROLE AND RESPONSIBILITIES Study Medical Monitoring Partner with medical monitor(s) in study oversight, data review, and interpretation across assigned programs — initially the pivotal PiNACLE and PiNACLE-H2H studies, with agility to pivot and support other programs as organizational needs evolve. Support the medical monitor in execution of clinical trials, ensuring adherence to the protocol, regulatory requirements, and Good Clinical Practice (GCP) guidelines. Contribute to patient safety monitoring by partnering with the medical monitor to identify and support site management of adverse events per protocol requirements, including required timely reporting to regulatory bodies. Protocol Design & Clinical Trial Planning Collaborate in the design and development of clinical trial protocols, ensuring they meet scientific, medical, and regulatory requirements, including selection of endpoints and patient populations. Assist in the planning and design of clinical trials, including the selection of endpoints and patient populations. Data Review, Interpretation & Publications Coordinate cross-functionally with the study team to ensure accurate and timely data collection, analysis, and reporting; assist with review and interpretation of clinical and translational data to make informed decisions about study execution. Plan and coordinate data cleaning activities to support the data analyses needed for planned publications (abstracts, presentations, and manuscripts). Regulatory Submissions & Documentation Support and contribute to the preparation and review of documents for regulatory submissions (IND, BLA, etc.), including clinical study reports, Investigator’s Brochures, and responses to regulatory agency inquiries. Cross-Functional & External Collaboration Collaborate cross-functionally with key Lyell study and program teams — including (but not limited to) Clinical Operations, Translational Sciences, Biostatistics, Data Management, Pharmacovigilance, Regulatory Affairs, and Medical Affairs — to ensure seamless trial execution. Contribute to regularly planned and ad hoc interactions with external stakeholders and vendors, including study site investigators and staff, steering committees, Safety/Data Monitoring Committees, key opinion leaders (KOLs), and Contract Research Organizations (CROs), to collaboratively identify issues and solutions, facilitate trial operations and patient enrollment, and maintain high standards of scientific integrity. Participate in and support pan-study external meetings (e.g., regularly planned site study staff meetings and PI/Sub-I meetings), as well as site visits and meetings with PIs/Sub-Is/staff. Support preparations for, and participate as requested in, medical-scientific meetings/congresses, study steering committee meetings, and SMC/DMC preparations and meetings. Innovation & Risk Management Identify opportunities for innovation and improvement in clinical trial methodologies and therapeutic approaches, including use of Artificial Intelligence methods. Consistently monitor for risks and recommend actions to address issues in a timely manner. PREFERRED EDUCATION PhD, PharmD, PA-C, ARNP, MS, or BSRN in a related field.
