Job Summary

Amgen is a leading biotechnology company with a mission to serve patients around the world. As a science-based, patient-focused organization, we discover and develop innovative therapies to treat serious illnesses.

Amgen's Attribute Sciences (AS) department within the Process Development (PD) organization defines the favorable quality characteristics of the therapies it produces and optimizes state-of-the-art analytical tools to guide that development. The Pivotal PD organizations focus is developing and commercializing robust manufacturing processes across a wide range of therapeutic modalities, including (but not limited to) synthetic medicines (oligonucleotides and small molecules), monoclonal and bispecific antibodies, bispecific T-cell engagers ("BiTEs"), and live oncolytic viruses.

Located at our Thousand Oaks, CA office the PD Principal Scientist will work to provide strategic analytical leadership (as an Attribute Sciences team lead and group lead) to teams developing commercializable manufacturing processes for oligonucleotide therapeutics and collaborate closely with Drug Substance and Drug Product colleagues.

Key responsibilities:
  • Supervise a team that provides analytical data to support Drug Substance and Drug Product oligonucleotide therapeutic development, including purity analysis, chiral purity, and structural elucidation using mass spectrometry, Fourier Transform Infrared (FTIR), and Nuclear Magnetic Resonance (NMR)
  • Act as an Attribute Sciences Team lead for an oligonucleotide program in pivotal clinical process development, being responsible for all analytical work to support the program
  • Define the analytical target profile (ATP) for methods used to monitor product quality. Based on the ATP, oversee the development, qualification, remediation, and transfer of analytical methods to Quality Control
  • Manage activities at contract manufacturing and testing sites
  • Author technical reports and analytical Chemistry, Manufacturing and Controls (CMC) sections in regulatory documents. Answer analytical and product quality questions from health authorities
  • Drive product characterization in support of process comparability studies, regulatory filings, regulatory questions, and reference standard qualification
