About Sail Biomedicines:

Sail Biomedicines is harnessing evolutionary and artificial intelligence to revolutionize programmable medicines. Sail’s platform combines first-in-class programmable RNA technology (Endless RNATM 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 building a wealth of data, enabling 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.

The Role:

To fully unlock programmability of RNA medicines, Sail is building a general purpose artificial intelligence (AI) platform to engineer translatable eRNA payloads as well as deployment nanoparticles to shuttle payloads to specific cells of interest. Sail’s AI platform enables optimal design of eRNA-NP formulations with desired, high-dimensional therapeutic requirements. As part of this exciting company, the successful candidate will lead the development and application of cutting edge AI paradigms for machine guided design of RNAs as well as RNA-deployment nanoparticles. The candidate will lead a team of AI scientists and collaborate closely with experimental biology, computational biology, chemistry and clinical application teams to advance our scientific mission towards designing a programmable medicine platform. The candidate should have a strong applied AI background and be impact driven, with a sharp operational acumen.
