Careers

Each summer, the Center for Computational Quantum Physics hires seasonal, full-time research interns interested in developing and implementing the concepts, algorithms and codes needed to understand the quantum mechanical behavior of many-particle systems, and to translate this understanding into useful predictions of the behavior of molecules and materials. Under the mentorship of one or more CCQ scientists during the summer, Research Assistants/Associates will contribute to CCQ research by joining an ongoing research project.

These are paid, temporary full-time positions based onsite at the foundation here in New York City. Applications are accepted from December 1st until mid-January for the upcoming summer.

The Center for Computational Quantum Physics’ (CCQ) Predoctoral Program provides graduate students pursuing their Ph.D. in a relevant field the opportunity to be employed at the CCQ for the purpose of working on a research project with one or more CCQ staff mentors. Applicants for these positions must have the approval of their thesis advisor.
These are paid, temporary full-time positions based onsite at the foundation here in New York City. There are two predoctoral sessions each year- Fall and Spring. Applications for the Fall sessions are accepted from mid-February until early April. Applications for the Spring session are accepted beginning in early July until early September.

The Center for Computational Quantum Physics (CCQ) of the Simons Foundation’s Flatiron Institute invites applications for 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 2026 and November 2026. Applications will be reviewed beginning in Fall 2025 and considered on a rolling basis until the positions are filled. For full consideration, application by October 12, 2025 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.

Flatiron Research Fellows-Software are positions for scientists who have recently completed the PhD , plan work related to the quantum many-body problem that is more directly aligned with our software and coding efforts.

The Center for Computational Quantum Physics (CCQ) of the Simons Foundation’s Flatiron Institute invites applications for an Associate Research Scientist-Software position. In exceptional circumstances appointment at the research scientist level may be considered. The CCQ seeks candidates for the development of a CCQ quantum Monte Carlo software suite devoted to general-purpose, high-performance auxiliary-field quantum Monte Carlo computations, as well as assistance with the development and maintenance of other software suites as needed.
 
Associate Research Scientists-Software at CCQ are typically appointed for an initial 3 year period, with a possible extension for an additional 3 years. Promotion to a non term-limited Research Scientist-Software position is possible upon review. Starting dates are flexible, typically between July and December 2026. For full consideration, application by October 15, 2024 is recommended – review of applications will start soon after that date. Applications will be considered on a rolling basis until the position is filled.

The Center for Computational Quantum Physics (CCQ) and the Initiative for Computational Catalysis (ICC) invite applications for a joint Associate Research Scientist position. Consideration will be given to applicants in areas of research relevant to both centers, such as first-principles electronic structure methods for strongly correlated molecules and materials, quantum embedding for energies and forces, electronic and nonadiabatic dynamics, machine learning, and data-driven approaches to electronic structure and dynamics.

Associate Research Scientists at CCQ and ICC are researchers who develop theoretical concepts, algorithms, and codes, and apply these to obtain new insights into the electronic structure and dynamics of molecules and materials. Associate Research Scientists develop their own research programs and also work in collaboration with other scientists, including postdoctoral fellows. Reporting to the directors of CCQ and ICC, these positions are based at the Simons Foundation in New York City.

The Center for Computational Quantum Physics (CCQ) invites applications for an Associate Research Scientist position at CCQ. Applicants should have a strong background and research agenda in one or several fields of relevance to CCQ, including: computational theories of quantum materials, computational approaches to the quantum many-body problem, machine-learning/artificial intelligence approaches to quantum systems.

Associate Research Scientists at CCQ are researchers who develop theoretical concepts, algorithms and codes, and apply these to obtain new insights into the quantum-mechanical behavior of models, materials and molecules. They develop their own research programs and also work in collaboration with other CCQ scientists including postdoctoral fellows. Reporting to research scientists, and/or the director or co-director of CCQ as appropriate, these positions are based at the Flatiron Institute, Simons Foundation in New York City.
