Scientist I/II, Analytical Development

Position Summary 
The Scientist, Analytical Development will be a key member of the Analytical Development group at PepGen. The successful candidate will have great opportunities to use state-of art instruments for studying various potential drug candidates to ultimately create transformational therapies for patients with neuromuscular disease. The candidate will lead method development and provide analytical support for in-house drug discovery and development activities. The successful candidate also will work very closely with experienced CMC and discovery teams to develop and qualify phase-appropriate analytical methods for various chemical entities like peptides, oligos and PepGen´s proprietary enhanced delivery oligonucleotides (EDOs), which is essential to the quality of therapies for patients. This is lab based role that will be on-site 5 days/week. 


  • Work closely with managers to develop analytical methods (LC-UV and/or LC-MS) for the purity analysis and impurity characterization of small molecules, peptides, Phosphonodiamidite Morpholino Oligomers (PMOs), and Peptide Conjugated Phosphorodiamidate Morpholino Oligomers (PPMOs). 
  • ​​​​​Provide analytical support to internal discovery and development activities, including stability sample analysis/characterization and forced degradation sample preparation and characterization.
  • Write and review analytical protocol and report for in-house analytical activities and prepare analytical source documents to summarize analytical activities for regulatory filing.
  • Perform routine maintenance of analytical equipment, HPLC systems, balance, pH meters, etc.; contribute to new instrument setup.
  • Foster a culture of collaboration, innovation, discovery, and cutting-edge research culture focused on scientific excellence, open communication, and continual improvement. 


  • Ph.D. in Chemistry or related area and 1+ years’ or MS degree and >5 years’ relevant experience in analytical development in pharmaceutical/biotech setting. Title will depend on the experience level of the successful candidate. 
  • Hands-on method development experience in HPLC and MS (e.g. TOF, QTOF, etc.) is a must. 
  • Experience in the method transfer, qualification, and validation of chromatographic methods (HPLC, GC, LC-MS, CE, etc.) is preferred. 
  • Good working knowledge of current Good Manufacturing Practices (cGMPs) or Good Lab Practices (GLP) is a plus.  
  • Familiarity with analytical support for early discovery and formulation development is a plus. 
  • Ability to effectively prioritize and deliver on tight timelines and work in a fast paced/dynamic team environment.
