Senior Scientist - Cancer Cell Biology

Pfizer • San Diego, CA

1d • Onsite

About The Position

Pfizer’s purpose is to deliver breakthroughs that change patients’ lives. Research and Development is at the heart of fulfilling that purpose—translating science and technology into therapies and vaccines that matter most. Whether in discovery, development, or clinical research, you will be a key contributor to our mission of bringing best‑in‑class medicines to patients worldwide. The Pfizer Oncology Research Unit (ORU) is working to change the trajectory of cancer by translating breakthrough discoveries into transformative medicines for patients. The Oncogene & Cancer Vulnerabilities (O&CV) group, within the Tumor Biology division, applies cutting‑edge science and innovative technology-first approaches to discover and advance novel cancer therapies. O&CV supports both small‑ and large‑molecule discovery programs, spanning target discovery and validation through clinical entry, serving as biology leaders across oncology portfolio programs. In this role, you will be an integral contributor to efforts aimed at targeting oncogenic drivers and tumor‑intrinsic vulnerabilities using next-generation small and large molecule modalities. You will design, execute, and interpret molecular and cellular experiments—including functional genomics—and integrate data across platforms to inform mechanism of action and resistance mitigation strategies. You will collaborate broadly across Pfizer, communicate findings effectively, and contribute to a culture of scientific excellence and continuous development.
