What you will do

Let's do this! Let's change the world!

Amgen is seeking a highly motivated Senior Principal Scientist for their Discovery Analytical Chemistry group in their state-of-the-art research and development facility in Genome Valley, India.

The Principal Scientist will lead analytical strategy and execution for drug discovery-stage projects, enabling medicinal chemistry and early candidate selection through deep expertise in analytical and separation sciences. This role bridges synthetic and analytical chemistry, ensuring rapid, reliable characterization of novel compounds and intermediates that drive Amgen's small molecule discovery pipeline.

Key responsibilities:

• The successful candidate will lead and manage the Synthetic Separations group, providing strategic direction, technical leadership, and mentorship to staff while prioritizing workloads, optimizing team performance, and serving as both a people manager and subject matter expert in synthetic separations.
• Design and qualify automated workflows enabling rapid turnaround and consistent data quality for purification and analysis of diverse compound libraries.
• Utilization of a diverse set of instruments and technologies, such as (but not limited to) HPLC, SFC, MS, mass-directed purification, and preparative-scale SFC and LC is necessary.
• Lead library purification efforts across multiple scales, ranging from microgram-level purification of screening compounds to hundreds of milligrams for advanced characterization.
• The successful candidate is also expected to assist in research efforts directed at improving process efficiencies, expanding the range of assays and applications, building state-of-the-art analytical capabilities, and improving technologies and infrastructure.
