Principal, Quality Assurance

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 Principal, Quality Assurance is responsible for providing Quality oversight and leadership across product lifecycle activities in a cell therapy environment. This role partners closely with Manufacturing, MSAT, Process Development, and Regulatory to support process implementation, technology transfer, raw material qualification, process validation, and commercialization efforts including preparation for Biologics License Application (BLA) submission(s).

PREFERRED EXPERIENCE:

• 10-15 years of experience in GMP biopharmaceutical operations including 4 years in cell therapy and/or lentiviral manufacturing operations.
• Minimum of 5+ years in Quality Assurance.
• Direct experience supporting BLA submissions, regulatory filings, and/or health authority inspections.
• Experience in commercial manufacturing and post-approval lifecycle management.

PHYSICAL REQUIREMENTS:

The physical demands described here are representative of those that must be met by an employee to successfully perform the essential functions of the job. While performing their duties, the employee must be able to do the following:

• Confirm visual information in the environment such as batch record and SOP steps were completed properly, parameters on equipment and computer screens, status of materials and equipment, and perform visual inspection of materials and product.
