2026 Flagship Pioneering Fellowship

What if there were an apprenticeship for scientific imagination? 

Flagship Pioneering is a biotechnology company that invents and builds platform and product companies that change the world. We bring together the greatest scientific minds with entrepreneurial company builders and assemble the capital to allow them to take courageous leaps. Those big leaps in human health and sustainability exponentially accelerate scientific progress in areas ranging from cancer detection and treatment to nature-positive agriculture.    

What sets Flagship apart is our ability to unite scientific and technical innovation, company creation, and capital investment under one roof in a way that is largely without precedent. Our scientific founders, entrepreneurial leaders, and professional capital managers are aligned around an institutionalized process that enables us to innovate and transform for the benefit of people and planet.    

Flagship-founded companies 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 named to Fast Company’s annual list of the World’s Most Innovative Companies three times.  

About the Fellowship 

We are looking for extraordinary, early career scientists, engineers, and physicians for our 2026 class of Flagship Pioneering Fellows. Immersed in our unique company creation process, Fellows start by asking “What if” or “If only.” Working in teams, they combine their scientific and technical instincts with unconstrained creativity to generate novel scientific and technology concepts that push beyond existing scholarship and challenge dogma. Fellows then learn to iterate, challenge, and shape these ideas into unreasonable, compelling hypotheses with the potential to produce pioneering new ventures. 

A summer as a Flagship Pioneering Fellow is an intense, exciting, unrivaled opportunity to learn our pioneering approach to building breakthrough companies that change the world.

• Learn and implement Flagship Pioneering’s unique process of generating and refining actionable, pioneering venture hypotheses
