What You Will Achieve

As a Principal Scientist, you will be at the center of our operations and you'll find that everything we do, every day, is in line with an unwavering commitment to quality. You will have the important role to generate high-quality immunoassay data in a regulated cGLP laboratory setting to support Pfizer's vaccine programs according to Standard Operating Procedures. You will support the technology transfer of assays, manage clinical sample testing and associated assays, and oversee clinical testing-associated functions at external Clinical Research Organizations (CRO).

In addition, you will work with the leadership to plan, design and critically analyze experiments to support the development and qualification/validation of assays at CROs as well as monitor assay performance and actively lead efforts in assay investigations. You will also identify new opportunities for collaboration and outsourcing of Pfizer clinical sample testing needs. Your skills and expertise will ensure that all work is managed in a compliant manner according to relevant Standard Operating Procedures and cGLP (current Good Laboratory Practice) and/or cGMP (current Good Manufacturing Practices).

You will be recognized as a technical expert and a significant scientific contributor. With your deep knowledge of the discipline, you will regularly contribute at the therapeutic area level and can represent the department on multidisciplinary teams. You will be using your scientific judgment to adapt standard methods and techniques by applying prior work experience. You will undertake mentoring activities to guide team members.

Sunshine Act

Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act. Therefore, if you are a licensed physician who incurs recruiting expenses as a result of interviewing with Pfizer that we pay or reimburse, your name, address and the amount of payments made currently will be reported to the government. If you have questions regarding this matter, please do not hesitate to contact your Talent Acquisition representative.
