The Senior Scientist will lead studies on colloidal and suspension characterization applying advanced techniques for formulation and process development particularly in biotherapeutics like vaccines.

Job Summary
The Senior Scientist will serve as a subject matter expert in colloidal and suspension characterization. The candidate will be an individual technical contributor within the Biotherapeutics Pharmaceutical Sciences organization supporting formulation and process development for complex biotherapeutic modalities including vaccines. The role requires strong scientific judgment advanced material characterization capability and the ability to derive meaningful structure-property insights that inform formulation design process robustness and product understanding. The successful candidate will apply modern characterization and data analysis approaches to interrogate material attributes product behavior and processing outcomes. This position requires a high level of technical independence cross-functional collaboration and clear scientific communication.
Primary Responsibilities

• Design and execute studies aimed at developing structure-property relationships that clarify how formulation components material attributes and processing conditions influence product performance and manufacturability.

• Apply a range of advanced physical characterization and visualization techniques-including microstructural assessment targeted rheological evaluation and quantitative image or morphology analysis-while selecting the appropriate methods based on scientific need.

• Develop and utilize enhanced data processing approaches (e.g. multivariate analysis computational visualization image derived metrics) to translate complex data into clear mechanistic understanding.

• Integrate experimental findings into formulation and process development strategies supporting identification of critical attributes definition of design spaces and establishment of robust process controls.

• Prepare high-quality technical documentation including study protocols data summaries technical reports and cross-functional presentations ensuring clear articulation of scientific rationale and conclusions.

• Evaluate and implement emerging analytical technologies or workflows that enhance organizational capability in physical characterization material assessment or predictive understanding.

• Provide scientific input to cross-disciplinary project teams contributing to problem-solving technical investigations and data driven decision-making.

Basic Qualifications

• PhD in Pharmaceutical Sciences Chemical Engineering Materials Science Physical Chemistry or a related discipline with 0-3 years of experience M.S. with 7+ years of relevant experience; or B.S. with 10+ years of relevant industry experience.
• Demonstrated experience characterizing complex formulations and interpreting physical property data in a mechanistic context.
• Familiarity with techniques used to characterize physical behavior and microstructure (e.g. colloid characterization microscopy-based methods quantitative imaging).

• Strong data analysis skills including statistical interpretation and integration of multimodal datasets.

• Proven ability to independently design execute and interpret complex studies with scientific rigor.

• Excellent written and verbal communication skills with the ability to present and justify scientific conclusions effectively.

Preferred Qualifications

• Experience with vaccine formulations or other complex biologic drug products.
• Working knowledge of process development principles including scaleup considerations critical attribute identification and risk-based development frameworks.
• A demonstrated track record of scientific impact through publications presentations or technology development.
