Careers

The Simons Foundation’s Flatiron Institute seeks a full-time Research Fellow position as part of its new initiative, Polymathic AI, Building Foundation Models for Science. Recent advances in machine learning, including Large Language Models and diffusion-based generative models have driven significant advances in Artificial Intelligence. The Flatiron Institute seeks to leverage these ideas to develop the next generation of AI-powered scientific analysis tools, seeking more powerful and more interpretable models with broad applications to many scientific disciplines. Our group includes researchers from multiple scientific disciplines ranging from machine learning, to astrophysics, biology, neuroscience, and quantum computing.

The Center for Computational Biology is seeking an experienced software engineer to be the Project Lead for HumanBase (hb.flatironinstitute.org), a dynamic and interactive web-based platform that supports thousands of biomedical researchers in exploring the molecular mechanisms of human disease. This position is ideal for an experienced engineering leader with bioinformatics experience who thrives on solving complex problems at the intersection of large-scale data, advanced analytics, and scientific discovery. This is a high-impact role that directly advances the study of human genomics and disease.

The successful candidate will lead technical direction and execution, guide other software engineers, and collaborate closely with researchers at the Center for Computational Biology to translate cutting-edge computational biology into robust software tools. The Project Lead will be a hands-on engineering leader with experience in biological data and -omics technology, as well as a complementary skillset that includes both writing high-quality code and managing a small team of software engineers. Success in this role depends on the ability to translate biological questions into computational solutions, collaborate closely with internal scientific stakeholders, and drive technically rigorous projects that advance our understanding of human biology.

The Initiative for Computational Catalysis (ICC) seeks temporary full-time Pre-doctoral Researchers as part of its Pre-Doctoral Program. This program provides graduate students pursuing their PhD in a relevant field the opportunity to be employed at the ICC for 4 months for the purpose of working on a research project with one or more ICC staff mentors. This position will be based onsite at the foundation in New York City.
 
Applicants for this position should indicate in their application one or more potential mentors at ICC and must have the approval of their thesis advisor. Pre-doctoral sessions will be held in the Fall and Spring. Applications submitted by May 29, 2026 will be considered for the Fall 2026 session. Applications submitted by August 28, 2026 will be considered for the Spring 2027 session.

The Center for Computational Quantum Physics (CCQ) of the Simons Foundation’s Flatiron Institute invites applications for multiple Flatiron Research Fellow and Flatiron Research Fellow-Software postdoctoral positions. The initial appointment is for two years with possible renewal for a third year. Starting dates are flexible, typically between August 2027 and November 2027. Applications will be reviewed beginning in Fall 2026 and considered on a rolling basis until the positions are filled. For full consideration, application by October 9, 2026 is recommended.

Flatiron Research Fellows are scientists who have recently completed the PhD and plan work on developing new concepts, algorithms, and codes needed to understand the many-particle quantum problem, and on the physical and chemical properties of systems requiring this new understanding.

The Center for Computational Quantum Physics (CCQ) of the Simons Foundation’s Flatiron Institute hires temporary, full-time Predoctoral Researchers for fall and spring sessions each year. This program provides graduate students pursuing their PhD in a relevant field the opportunity to be employed at the CCQ for four months for the purpose of working on a research project with one or more CCQ staff mentors. This position is based on-site at the foundation in New York City. We will not be accepting applications for the Spring 2027 session but will post for Fall 2027 in February.

Flatiron research fellows (FRFs) in ICC are individuals at the postdoctoral level with backgrounds in one or more of the following areas: theoretical chemistry, materials science, condensed matter physics, machine learning, applied mathematics, or computer science. Reporting to Research Scientists, Associate Research Scientists, or the co-Directors as appropriate, FRFs work on developing and applying new theories, methods, and software to understand the electronic structure and chemical dynamics of reactions in catalysis. Fellows are expected to disseminate their results through scientific publications, production of open-source software, participation in conferences, workshops, and seminars, and through mentorship of undergraduate and graduate students as appropriate. If applicable, an applicant can be hired into a Flatiron Research Fellow-Software position, suitable for a postdoctoral-level scientist with interests more directly aligned to our software and coding efforts.

The initial appointments are generally for two years, with the possibility of renewal for a third year, contingent on performance. FRFs may be eligible for subsidized housing within walking distance of the ICC. The anticipated start date is early September 2027.

Applications are invited for postdoctoral Flatiron Research Fellowships (FRF) at the Center for Computational Mathematics (CCM), in the Flatiron Institute, a division of the Simons Foundation. CCM has around 50 members, including scientists at career stages from recent Ph.D.s through to senior scientists, software engineers, support staff, and visitors. A major goal of the center is to develop the next generation of simulation and analysis methods, and to make them available to the scientific community through collaboration and software development.

The Center for Computational Quantum Physics (CCQ) of the Simons Foundation’s Flatiron Institute, jointly with the Department of Physics at Columbia University, invites applications for a position in the general area of theoretical/computational quantum condensed matter physics. The position is a 50-50 joint appointment between Columbia University and CCQ, with the appointee spending half of her or his effort in each place. At Columbia the opening is at the tenure track Assistant Professor level and, at CCQ, it is at the Associate Research Scientist level. The position is based at the Simons Foundation and Columbia offices in New York City. In order to be considered for this joint appointment, candidates must submit their application both with Columbia and with CCQ. Review of applications will start on or about November 15, 2026 and continue until the position is filled.
