Flagship Labs 63 Inc. (FL63) is a privately held, well-funded, early-stage platform biotechnology company that is leveraging emerging insights in RNA biology to develop a novel class of human therapeutics.

FL63 was founded by Flagship Pioneering, an innovation enterprise that conceives, resources and grows first-in-category life science companies. The firm’s institutional innovation foundry, Flagship Labs, is where teams of scientific entrepreneurs systematically evolve ideas and turn previously undiscovered areas of science into real-world ventures. Flagship has created over 100 scientific ventures resulting in >$19 billion in aggregate value, 500+ issued patents, and >50 clinical trials for novel therapeutic agents. Flagship’s portfolio companies include Moderna, Rubius Therapeutics, and Indigo Agriculture.

FL63 is a highly dynamic, entrepreneurial and innovation-driven organization seeking to hire a highly motivated and experienced research associate to join our Cell Biology team for performing cell/molecular biology assays to support the drug discovery program and cell line maintenance.
