POSITION TITLE:  Sr. Scientist/Principal Scientist/Associate Director Chemistry, Manufacturing and Control (CMC) Small Molecules


  • Work closely with Calibr’s scientists on development of lab-scale synthetic, analytical and formulation projects.
  • Develop synthetic plans and design and run experiments to test their suitability for large-scale use
  • Manage CMOs in API, formulation and fill/finish development and manufacturing in cost-effective manner. Improve and troubleshoot existing processes to reduce cost and increase reliability, purity, and safety
  • Use simulation or modelling software to analyze extensive data sets and determine how changes in process affect the final product
  • Utilize fundamental process chemistry principles to characterize and solve manufacturing process challenges. Use a variety of analytical methods to monitor reaction processes
  • Define critical quality attributes and establish robust control strategies via comprehensive process parameters assessment.
  • Ensure that regulatory starting materials and API process development and manufacturing activities are conducted in compliance with good manufacturing practices and applicable regulatory requirements by proactively overseeing process development and manufacturing campaigns.
  • Review batch records, process validation plans and protocols, manufacturing campaign reports.
  • Works cross-functionally to deliver regulatory documents and supporting documentation in support of Calibr’s regulatory filings.
  • Prepare technical reports, patent application content, publications and oral presentations as necessary.
