  • Expertise in developing high concentration protein formulations and resolving issues such as aggregation, viscosity, and solubility. Able to identify and mitigate formulation risks including precipitation and chemical degradation.
  • Design experiments, analyze data, and prepare technical protocols, reports, and development summaries.
  • Establish and drive scientific strategy, workflows, and best practices for early- to late-stage biologics formulation development, with the ability to operate independently in a dynamic, fast-paced, client-facing environment with evolving priorities.
  • Serve as a technical subject matter expert (SME) in client engagements, including proposals, presentations, and project reviews; prior line management or informal leadership experience is advantageous.
  • Collaborate effectively with cross-functional teams to align project timelines, priorities, and resource planning.
  • Mentor and develop junior scientists and technical staff, and support onboarding of new team members.
  • Evaluate and implement new technologies and platform approaches to enhance internal capabilities and drive innovation.
  • Ensure compliance with applicable quality, regulatory, and safety standards.
  • Perform additional responsibilities as required to support evolving business and project needs.
  • Occasional travel may be required (by land or air) to attend conferences, seminars, off-site client meetings, and marketing events as needed.

Minimum Qualifications:
  • Master's degree/PhD degree in Biochemistry, Chemistry, or related field and minimum 4-6 years of relevant experience and demonstrated working knowledge of scientific principles.
  • Prior experience in formulation development, stability studies, and analytical characterization of biologics or strong background in biochemical and biophysical characterization of proteins with deep understanding of protein structure and function.
