About The Position

Bristol Myers Squibb is on a mission to discover, develop, and deliver innovative medicines that help patients prevail over serious diseases. Guided by a commitment to rigorous science, integrity, and transformative innovation, BMS is a global biopharma leader dedicated to improving the lives of patients worldwide. In October 2025, BMS significantly expanded its RNA medicines capabilities through the acquisition of Orbital Therapeutics, bringing with it a powerful and differentiated RNA platform that combines circular and linear RNA engineering, advanced delivery technologies, and AI-driven design. This platform is accelerating BMS's efforts to pioneer a new generation of programmable RNA therapies across immunomodulation for autoimmune disease and oncology, next-generation vaccines, and protein therapeutics. As we continue to grow and integrate this delivery platform, we are building out a world-class LNP Process Development team based in Cambridge, MA. If you are passionate about cutting-edge RNA delivery science and want to contribute to medicines that have the potential to transform patient lives in ways not previously possible, we invite you to join us. Position Summary Bristol Myers Squibb is seeking a motivated and detail-oriented Senior Associate Scientist to join our LNP Process Development team in Cambridge, MA. The LNP PD team works to develop, characterize, and implement robust preclinical and clinical manufacturing processes to support Bristol Myers Squibb's exciting pipeline of products. This role is specifically focused on LNP process development, with responsibilities spanning early process development through clinical manufacturing support. This is an excellent opportunity for an early-career scientist to grow within a dynamic, fast-paced environment.
