Careers

FRF positions are initially two-year appointments, renewable for a third year contingent on performance. Fellows will be based, and have a principal office or workspace, at the Simons Foundation’s offices in New York City. Fellows may also be eligible for subsidized housing within walking distance of the Flatiron Institute. The start date is between July 2025 and October 2025.
 
Flatiron Research Fellows are mentored by one or more research scientists. They are also encouraged to carry out an independent research program, to collaborate across the various centers at the institute, to participate in the institute’s vibrant activities such as workshops and seminars, and to mentor students through our summer internship program. They are expected to disseminate their results through scientific publication, conferences, and/or software distribution. Fellows receive a generous travel and research budget, and have access to the institute’s powerful scientific computing resources.

The Simons Foundation is a private foundation established in 1994 in New York City by Jim and Marilyn Simons. With an annual grants and programs budget of $300 million, the foundation’s mission is to advance the frontiers of research in mathematics and the basic sciences. The foundation pursues its mission through its grant-making division, comprising programs in Mathematics & Physical Sciences, Life Sciences, Education & Outreach and autism research, and through its internal research division, the Flatiron Institute.

The Flatiron Institute, an internal research division of the Simons Foundation, is a community of scientists who are working to use modern computational tools to advance our understanding of science both through the analysis of large, rich datasets and through the simulations of physical processes. Our mission is to advance scientific research through computational methods, including data analysis, theory, modeling and simulation.

Applications are invited for either the Research Scientist or Senior Research Scientist level at the Center for Computational Mathematics (CCM), in the Flatiron Institute, in all our active areas of research. These include:

• machine learning, especially the areas of optimization, learning theory, probabilistic modeling, deep learning, and high dimensional data analysis, as well as applications of scientific interest at Flatiron (e.g., cosmological modeling, quantum many-body systems, computational neuroscience)
• statistical methodology, modeling, and inference
• probabilistic and differential programming
• computational physics, including biophysics, statistical mechanics, fluid mechanics, quantum physics, and molecular dynamics
• numerical methods for partial differential equations and integral equations
• signal and image processing, with a particular focus on cryo-electron microscopy
• numerical analysis, including numerical linear algebra and high-order methods
• high performance computing and open source software libraries

Applications are invited for paid, full-time research internships at the Center for Computational Mathematics (CCM) in all our active areas of research. CCM is one of five centers of the Flatiron Institute, an internal research division of the Simons Foundation. Our mission at CCM is to create new mathematical approaches, algorithms and software to advance scientific research in multiple disciplines, often in collaboration with other Flatiron Centers.

Tremendous opportunities exist at the intersection of mathematics, computer science, statistics, and their scientific applications, with the lines between theory, algorithm development and software implementation often blurred. Beyond the creation of new simulation and analysis methods, a major goal of CCM is to make these methods available to the scientific community. The Center also hosts an array of meetings, workshops and conferences, serving as a focal point for the field internationally.
