About Flagship Pioneering: Flagship Pioneering is a scientific innovation engine that originates and builds platform companies and products 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, exponentially accelerating scientific progress in human health, sustainability, and beyond. As part of our modeling and simulation team, you will partner across the Flagship ecosystem, from newly founded ventures to later-stage portfolio companies, applying mechanistic modeling approaches to help translate bold scientific ideas into transformative therapies. Position Summary: We are seeking a highly motivated individual to provide leadership and hands-on support for modeling efforts (PK/PD/QSP) across Flagship’s diverse drug discovery portfolio. The qualified candidate is expected to support internal and external due diligence work, provide guidance for Flagship platform companies to accelerate timelines from Lead ID to DC and to apply innovative modeling approaches to inform early feasibility concepts. As programs advance, the role extends through Lead OP and pre-IND, integrating modeling workstreams into cross-functional development strategy and, in collaboration with clinical teams, supporting the design and interpretation of emerging clinical data. We are seeking individuals with deep subject matter expertise who are analytical, goal-oriented and committed to maintaining the highest scientific and ethical standards. Strong communication skills and comfort to utilize AI-supported modeling workflows in a dynamic, cross-functional team environment are highly desirable.
