Principal Scientist

WHY PATIENTS NEED YOU

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.

WHAT YOU WILL ACHIEVE

You will be a computational chemist as an integral member of Medicinal Chemistry teams to apply computational techniques to impact drug discovery projects.

You will generate and evaluate hypotheses to assist molecular design decisions and influence project direction by deploying and/or developing computational methods and workflows.

A strong understanding of fundamental physical chemistry, biophysical chemistry, statistical mechanics, macromolecular structures and function, and familiarity with relevant modern computational models and strong scripting skills are required.

HOW YOU WILL ACHIEVE IT

• As an independent researcher and integral member of project teams, you will apply your experience and knowledge to determine the appropriate computational techniques to best drive projects forward.

• You will apply a wide variety of computational approaches including docking, cofolding, molecular dynamics, foundational AI models, both physics and AI/ML approach methods to conformational analyses, hit identification/optimization, structure-based drug design, ligand-based design, pharmacophore models, and QSAR modeling to generate and evaluate hypotheses and influence design decisions.

• You will also develop novel computational approaches and workflow to solve project-specific and general challenges in drug discovery

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.
