Why Patients Need You

Pfizer's purpose is to deliver breakthroughs that change patients' lives. Research and Development is at the heart of fulfilling Pfizer's purpose as we work to translate advanced science and technologies into the therapies and vaccines that matter most. Whether you are in the discovery sciences, ensuring drug safety and efficacy or supporting clinical trials, you will apply cutting edge design and process development capabilities to accelerate and bring the best in class medicines to patients around the world.

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 molecular data in a regulated laboratory setting to support Pfizer's vaccine programs according to Standard Operating Procedures which may exclusively be developed by you. Working in a team and frequently supporting diagnostic development for phase 3 vaccine programs, you will execute and oversee qualification and validation of molecular diagnostic assays and coordinate, as needed, assay lifecycle management activities which many included clinical testing and analysis of control and panel trending over time.

You will use collaborative teamwork to tackle complex projects and challenging timelines. 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 in molecular assay development and compliant clinical testing. With your deep knowledge of molecular biology and diagnostic assays, you will regularly contribute molecular diagnostic expertise and can represent the department on multidisciplinary teams. You will be using your scientific acumen to develop molecular diagnostics that address specific project requirements and evaluate new technologies where needed. As an expert in molecular biology, you are expected to supervise junior scientists and guide team member development.

How You Will Achieve It
  • Lead molecular diagnostic assay development projects and represent the group on multidisciplinary teams.
  • Leverage a team of analysts to execute project goals and deliver compliant results according to study timelines.
  • Design experiments to establish assay parameters such as precision, limit of detection, and specificity of molecular diagnostics and validate them for use to support phase 3 trials of vaccines and drug products.
  • Work collaboratively with numerous groups including statistics, informatics, project management, and clinical testing labs to meet assay development and clinical testing timelines.
  • Act as single point of accountability for assigned projects, interacting as necessary with stakeholders at all levels of management to convey project information and manage expectations.
  • Lead both manual and automated molecular diagnostic assay technology transfer to clinical testing groups in cGLP laboratory spaces to maintain efficient high throughput testing and achieve high-quality results.
  • Provide clear, concise and timely responses to project and/or clinical team requests for experimental information, and guide and develop laboratory-based scientists.
  • Satisfactorily complete all cGLP training and safety training in conformance with departmental requirements.


  • Master's degree with 10+ years' experience
  • Expertise in qPCR, DNA and RNA extraction and manipulation, experimental design, data analysis, and assay validation techniques will be key to this position
  • Strong experience in laboratory management including inventory and sample tracking, analyst scheduling, oversight of equipment documentation, and regulatory compliance
  • Breadth of knowledge of different areas of science, awareness of new technologies, and familiarity with current issues to apply novel and innovative approaches to problem solving
  • Excellent verbal and written communication skills
  • Proficiency in the use of Word processing, Excel, PowerPoint and relevant scientific software

  • PhD with 4+ years of relevant experience
  • Experience with laboratory automation, including Hamilton or open source pipetting robots
  • Managerial experience, preferably in a regulated environment such as GxP, CLIA, or ISO
  • Knowledge of next generation sequencing
