Scientist/Senior Scientist, Protein Purification


About Dragonfly
Founded in 2015 by Dr. Tyler Jacks, head of the Koch Institute at MIT, Dr. David Raulet, one of the world's leading experts in Natural Killer (NK) cell biology, and Bill Haney, a longtime tech entrepreneur and investor, Dragonfly Therapeutics develops novel first-in-class therapeutics targeted at Natural Killer cells and other cells of the innate immune system. Our therapies are designed to counterbalance immune suppressive factors present in the tumor microenvironment and mobilize anti-cancer immune responses, and are expected to be potent as single agents as well as in treatment combinations with existing cancer immunotherapies – such as T cell treatments.  Dragonfly’s Scientific Advisory Board and founders are major figures in cancer biology and immunology, and launched Dragonfly to harness the power of the immune system to provide breakthrough cancer treatments for patients.
Scientist/Senior Scientist, Protein Purification
We are looking for a highly motivated and talented biochemist to join our Biologics team. The successful candidate will be responsible for developing, implementing and performing protein purification of a wide variety of bispecific and trispecific antibody formats. He/She will be a key player in providing comprehensive biochemical characterization and developability assessment of different therapeutic candidates. The successful candidate will work with Dragonfly’s talented team to discover and develop therapies that stimulate immune responses against solid and hematologic cancers.
