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 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 be part of a team that is addressing the critical task of rejuvenating our pipeline with innovative, differentiated First-In-Class/ Only-In-Class programs in the years to come. This will be addressed by generation of strong data packages from target hypotheses derived from academic outreach and initiatives. You will be an essential member of this team and creatively design and execute key experiments to address the basic and translational biology of novel drug targets, their molecular pathways, and their connection to human disease. You will support projects in one or more therapeutic areas of interest to Pfizer including Immunology, Oncology, Immuno-Oncology, Neurodegenerative Disease, etc.

With your deep knowledge in the discipline, you will be an active team member who influences at the project team level. You will be using your scientific judgment to adapt standard methods and techniques by applying prior work experience and consulting others. Your ability to plan will help in preparing short-term work activities on projects. Your creativity in developing novel processes and new ideas will be used frequently. You will undertake mentoring activities to guide your team members.

It is your innovative scientific temperament that will help in making Pfizer ready to achieve new milestones and help patients across the globe.

The Discovery Fibrosis Group in the Inflammation and Immunology Research Unit (I&I) is looking for a motivated, innovative and enthusiastic researcher to join our group in studying the interplay between macrophages and fibrosis and developing novel therapeutics for the treatment of fibrotic diseases. This Senior Associate Scientist will work in a matrix structure within the department supporting both in vitro and in/ex vivo studies that investigate mechanisms for fibrosis and novel targets and assets for the Discovery Fibrosis Group. The ideal candidate will have an immunology background and the drive to learn new assays and technics. The candidate will be a key contributor in delivering data and recommendations for decisions of proposed and active fibrosis programs.

The Senior Associate Scientist will support a cross-disciplinary team of scientists focusing on inflammation and fibrosis. The team collaborates across research units to develop novel therapeutics at the intersection between immunology and these respective disciplines. He/She will help conduct experiments in breaking areas of science, collaborate with others to employ cutting edge technologies including high-parameter flow cytometry, optical microscopy, high content screening, systems immunology and single cell RNA techniques.

How You Will Achieve It

  • Contribute to achievement of goals of the team and influence at the work group/project team level.
  • Apply technical skills and functional knowledge to projects/ assignments within own work group/ project team independently and proactively.
