Senior Associate Scientist (EG90 Lvl2), LNP Process Development

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.
