Strong command of ICH E6, E8, E3 guidelines and FDA regulatory documentation requirements
Advanced degree in life sciences, pharmacy, or related discipline (PhD, PharmD, or MS preferred)
Ability to work independently, manage multiple deliverables, and thrive on compressed timelines
Experience with cell therapy, gene therapy, or autoimmune/immunology programs is a strong plus
