Senior Scientist, Assay Development

What if… you could join an organization that creates, resources, and builds life sciences companies that invent breakthrough technologies to transform health care? In today’s healthcare system, disease diagnosis often relies on invasive procedures, such as biopsies, which enable direct interrogation of cellular and tissue health at the suspected source of disease. Due to their invasiveness, cost, and general inconvenience to the patient, biopsies are often conducted after onset of symptomatic disease presenting one of the largest barriers to delivering interventions early in disease progression when they are likely to be most impactful. Flagship Labs 103, Inc. is a privately held early-stage company that is building advanced technological and computational platforms to pioneer the detection of cellular dynamics from minimally invasive biospecimens that can be leveraged to connect individuals to the most effective interventions to prevent onset and progression of disease. FL103 was founded by Flagship Pioneering, an innovation enterprise dedicated to originating and developing companies that invent breakthrough technologies that transform health care, agriculture, and sustainability. Since Flagship’s founding in 2000, the firm has originated and fostered more than 100 scientific ventures including Moderna Therapeutics, Generate Biomedicines, and Indigo Agriculture.
