Associate Director Finance

Who We Are

Flagship Pioneering is a biotechnology company that invents and builds platform companies that change the world. We bring together the greatest scientific minds with entrepreneurial company builders and assemble 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 advance biotechnology by uniting life science 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 each aligned around an institutionalized process that enables us to innovate and transform for the benefit of people and planet. 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. Position Summary The Associate Director, Finance, will be a key member of the Flagship Pioneering finance team, responsible for supporting financial planning, reporting, accounting, forecasting, and operational finance activities across primarily the Pioneering Medicine’s ( PM ) portfolio of internal and partnered programs. This individual will partner closely with PM leadership, program teams, functional leaders, and cross-functional finance and accounting stakeholders to provide financial insight, strengthen budget discipline, and support timely, high-quality decision-making in a dynamic biotechnology environment.

The role will manage core finance activities across assigned PM entities and programs, including budget-to-actuals, cash flow monitoring, management reporting, forecasting, close support, collaboration partner reporting, and ad hoc analysis. The Associate Director will also help improve finance processes, reporting standards, systems, and controls.
