Codiak BioSciences is seeking a Scientist, Purification (Downstream PD) to develop the company’s novel exosome purification platform. Responsibilities will include providing technical/scientific expertise and leadership in all downstream areas, such as filtration, centrifugation, various types of chromatography, high throughput technology, virus inactivation, formulation, etc.  Background in biochemistry, bioanalytics, virus production and purification will be a plus. Understanding of exosome biology, isolation and characterization will be an additional advantage. This is a unique opportunity for a strong scientist/biochemical engineer to contribute experimentally, as well as intellectually, to both early- and late-stage development of a novel exosome production platform. As part of a start-up, the candidate will be uniquely exposed to the full range of company activities within and outside the lab. The candidate will also play a critical role in helping shape Codiak’s scientific and business direction.

About Our Organization

Codiak BioSciences is leveraging recent advances in the biology of extracellular vesicles and their role in intercellular communication. Codiak aims to become the world’s leading company in developing exosomes as a new therapeutic and diagnostic modality for the treatment of a wide array of diseases, including cancer. Recent discoveries have demonstrated that exosomes derived from normal cells can act as a potent and safe delivery system for multiple therapeutic payloads. These small vesicles, which leave cells and travel throughout the body, can mediate dramatic effects in animal models of disease. The group has also shown that exosomes derived from cancer cells contain specific proteins on their surface that can be used to quickly detect and characterize cancer from a sample of patient’s blood. They can also be used to monitor the response to cancer treatment, and to detect relapses.
