Senior Associate Scientist

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.

As a Senior Associate Scientist, you will be at the center of our scientific vaccine operations and you'll find that everything we do, every day, is in line with an unwavering commitment to quality. You will join a team leading the important role of generating viruses such as human parainfluenza virus (HPIV), human cytomegalovirus (HCMV), influenza viruses, and SARS-CoV-2 under BSL-2 and BSL-3 conditions. Primary responsibilities will include maintaining mammalian cell culture, optimizing virus propagations in cells to produce high titer stocks for vaccine efficacy research, performing virus characterization assays, and coordinating with teams across the site to ensure viral reagent needs are met. You will manage and update reagent inventories, plan and execute production of virus batches, and organize virus distributions to other groups within Pfizer to meet critical deadlines supporting vaccine research and development. Other responsibilities will include collaborating on data and information transfer between groups, development and integration of laboratory immunoassays, and supporting high throughput assay activities and testing for clinical and non-clinical research programs.

Your strong foundation in general scientific practice and its principles and concepts will help in meeting critical deadlines. You will be relied on as a technical contributor to assess the assigned tasks and make decisions that involve direct application of your knowledge. It is your hard work and focus that will make Pfizer ready to achieve new milestones and help patients across the globe.
