Research Associate II, Preclinical Manufacturing
About The Position
Sail Biomedicines is pioneering the integrative design and deployment of fully programmable medicines to transform patient care. Sail’s platform combines first-in-class programmable circular RNA technology (Endless RNA™ or eRNA), and an industry-leading platform of programmable nanoparticles, utilizing natural components, to unlock comprehensive programming of medicines for the first time. By leveraging cutting-edge eRNA and nanoparticle deployment technology, Sail is also making unparalleled use of AI techniques to identify and design fully programmable medicines that are potent, targeted, versatile, and tunable. Sail was founded by Flagship Pioneering. Sail Biomedicines is seeking a Research Associate II to join our Preclinical Manufacturing team, supporting the production of RNA and lipid nanoparticle (LNP) drug substances and drug products. As part of the Technical Operations group, you will contribute directly to the development and delivery of preclinical materials for both internal and partnered programs. Thisis a hands-on, lab-based role requiring strong experimental execution, attention to detail, and cross-functional collaboration. You will play a key role in advancing scalable RNA and LNP manufacturing processes to enable pipeline progress.
