The Importance of the Role
The Early Research and Process Development (ERPD) group is seeking a Scientist II with experience in biologics preformulation and developability assessment, with a focus on proteins, antibodies, and antibody-oligonucleotide conjugates (AOCs). This individual will support the assessment of developability for lead molecules through comprehensive evaluations, including biophysical characterization, forced degradation, and short-term, long-term, and in-use stability studies.

The successful candidate will leverage high-throughput formulation tools and workflows to characterize product stability across a broad range of conditions, including process buffers, excipients, concentrations, hold times, and temperatures. In collaboration with Analytical Development, the candidate will help define quality attributes and implement stability-indicating assays appropriate for early-stage programs. The Scientist II will also consider route-of-administration factors, such as subcutaneous delivery, during early formulation assessments (e.g., stability and viscosity at high concentrations, potential enabling approaches).

This role requires strong cross-functional engagement, working closely with Upstream and Downstream Process Development, High-Throughput Automation, and CMC Drug Substance/Drug Product teams to foster a collaborative environment that enables the advancement of robust and scalable manufacturing processes. The Scientist II will contribute formulation recommendations to research, pilot-scale, and commercial-scale manufacturing groups and generate scientifically rigorous data packages to inform preclinical and early clinical development and enable downstream CMC strategy for Sarepta's genetic therapy engine.

The Opportunity to Make a Difference

• • Plan and execute formulation experiments to assess and optimize the stability of key intermediates and final products throughout the manufacturing process.
  
  
  • Establish developability profiles for candidate molecules, incorporating considerations for route-of-administration.
  
  
  • Identify formulation-relevant critical quality attributes for key intermediates and drug product candidates and guide the development of stability-indicating assays to monitor them.
  
  
  • Contribute scientific recommendations regarding formulation technologies and instrumentation.
  
  
  • Support cross-functional teams by providing recommendations on product handling and storage considerations.
  
  
  • Prepare and review methods, protocols, and technical reports for regulatory submissions or technology transfer.
  
  
  • Train and support Research Associates in experimental execution, troubleshooting, and data interpretation.
