Job Description
ROLE SUMMARY
This scientific leadership role sits within Pfizers Biotherapeutics Pharmaceutical Sciences organization and is part of the Pharmaceutical Research & Development (PhRD) department. As Principal Scientist you will lead formulation development and physico-chemical characterization efforts for Pfizers biotherapeutics portfolio which includes antibody-drug conjugates (ADCs) nucleic acid delivery systems monoclonal antibodies antibody constructs proteins and vaccines.
Initially focused on supporting the ADC portfolio this role requires working in a dynamic interdisciplinary environment to advance preclinical clinical and commercial development programs. You will be responsible for scale-up and technology transfer activities ensuring robust and scalable formulation strategies that meet regulatory and manufacturing requirements.
The ideal candidate will contribute to regulatory documentation by generating source materials for formulation selection and characterization. Success in this role demands exceptional time management strong communication skills and meticulous attention to detail. A broad understanding of analytical methodologies biophysical characterization techniques and formulation design principles is essential along with experience in process development and drug delivery technologies.
ROLE RESPONSIBILITIES
You will be responsible for conducting experiments to support the development evaluation and characterization of formulations processes components and delivery technologies for a wide range of therapeutic modalities. These include but are not limited to candidate molecules derived from mammalian and microbial fermentation peptides antibody-drug conjugates (ADCs) and targeted delivery strategies.
This role requires close collaboration with cross-functional teams to advance project goals. You will demonstrate technical awareness across various aspects of drug discovery and development and lead technical project teams that apply characterization and stability data to design dosage forms that meet both clinical and commercial requirements.
You are expected to show a strong drive for learning new techniques a deep scientific commitment and the ability to make impactful contributions within the Pharmaceutical Research and Development (PhRD) team and broader project teams.
Responsibilities include:
Design execute and analyze experiments for existing and novel modalities. Define the appropriate parenteral dosage form formulation process design scale up approaches identify critical parameters and define the design space
Support development of novel characterization techniques to characterize formulations to support process development and formulation design.
Lead experiments to confirm robust process performance across the control space. Compile experimental and analytical results perform data interpretation summarize and report on data with conclusions and recommended next steps
Provide technical representation and subject matter expertise (SME) in cross functional project teams
Provides leadership and mentorship to matrixed program team colleagues
Collect and share relevant academic literature leverage external consultants/SMEs and establish new collaborations with internal groups. Optimize current processes to ensure robust manufacturing of Pfizers biotherapeutic portfolio
