Senior Principal Scientist, Pre-Formulation and Materials Science

ROLE SUMMARY

This Senior Principal Scientist position will be a strong scientific and leadership role within the Early Formulation Science and Drug Delivery (EFS-DD) group, supporting early-stage drug and drug product design, materials science characterization and strategy, and biopharmaceutics understanding as well as early clinical drug delivery strategy of new small molecules.   

The selected candidate will interface with multi-disciplinary research project teams and cross functional management to provide guidance, input and direction on molecular design, dosage form design, solid form strategy, and biopharmaceutics aspects of pre-clinical and clinical candidate development. The role will also focus on developing and demonstrating leadership and drug delivery strategy skills within the Drug Product Design and Supply department which functions as part of the larger Pharmaceutical Sciences division.  

Key activities/abilities include: 

• Understanding of connectivity of molecular structure, solution kinetics, thermodynamics, diffusion and permeation of molecules across membranes 
• Strong fundamental understanding of molecular and supramolecular interactions of small molecules in aqueous environments 
• Ability and interest to understand and probe molecular/supramolecular interactions of small molecules in common enabling drug delivery technologies; desire to optimize system properties to achieve required delivery profiles for pre-clinical and clinical studies 
• Strong fundamental understanding of principles governing crystallization and polymorph behavior, characterization techniques for crystalline and amorphous solid forms, and impacts of solid form on stability, manufacturability, and bio-performance of small molecule drug candidates and drug products
• Efficient application of existing advanced modeling and simulation tools for predictive performance of oral absorption and systemic exposure (pharmacokinetics) in pre-clinical and clinical studies 
• Development and advancement of the concepts of early translational biopharmaceutics with a focus to improve predictive capabilities by linking in vitro drug and drug product performance attributes to in vivo performance attributes 
• Lead matrix teams of scientists across multiple levels to deliver portfolio and initiative breakthroughs 
• Lead scientific strategy and set direction for advances in oral, small molecule drug delivery through interaction with organizational thought leaders and cross functional management 
• Maintain an awareness of and contribute to current relevant scientific literature 
• Conduct novel scientific research and present significant findings via internal and external presentations or publications

• Knowledge in biology/pharmacology/drug discovery /drug delivery up to Proof of Concept (POC) studies. 
• Small molecule Formulation and/or early Biopharmaceutics, Materials Science, or Pharmacokinetics background, and a strong record of scientific achievement.  
• Experience in using and interpreting biophysical modeling, physicochemical (solubility & dissolution) and biological (passive, transporter mediated, efflux) transport phenomena, design, interpretation, and use of in vitro experiments, or in vivo/in vitro drug metabolism studies, and interpretation of pre-clinical exposure data for the design and selection of new small molecule drug candidates and drug delivery systems 
• A strong interest and motivation to learn and implement new technologies and concepts. 
• A strong interest in leadership  
• Extensive practical experience working within cross-disciplinary teams and achieving results in a matrix environment. 
• Excellent organizational and communication (oral and written) skills.  
• The ability to work independently, as well as collaboratively. 

PREFERRED QUALIFICATIONS 

• Proven track record of supervising, mentoring and coaching scientists. 
• Understanding of drug discovery and development concepts 
• Experience in actively developing and advancing scientific initiatives and external collaborations. 
• Collaborative and effective partnering skills applied in a complex, multi-disciplinary organizational model. 

 
Candidate demonstrates a breadth of diverse leadership experiences and capabilities including: the ability to influence and collaborate with peers, develop and coach others, oversee and guide the work of other colleagues to achieve meaningful outcomes and create business impact.
