Senior Research Associate, Platform Biology

Cambridge, MA USA

Apriori Bio is an early-stage biotechnology company with an ambitious and exciting mission: to lay the foundation for Global Pathogen Shield™ protective interventions that can neutralize a wide range of the most dangerous and rapidly evolving infectious pathogen threats. The company is developing a revolutionary approach to this challenge and recruiting a team of top-tier scientists to build what it believes will be a powerful, first-in-category R&D platform.

Apriori Bio was founded by Flagship Pioneering, a biotechnology company that invents and builds platform companies, each with the potential for multiple products that transform human health or sustainability. Since its launch in 2000, Flagship has originated and fostered more than 100 scientific ventures, resulting in more than $90 billion in aggregate value. Many of the companies Flagship has founded have addressed humanity’s most urgent challenges: vaccinating billions of people against COVID-19, curing intractable diseases, improving human health, preempting illness, and feeding the world by improving the resiliency and sustainability of agriculture.

Flagship has been recognized twice on FORTUNE’s “Change the World” list, an annual ranking of companies that have made a positive social and environmental impact through activities that are part of their core business strategies, and has been twice named to Fast Company’s annual list of the World’s Most Innovative Companies.
