Flatiron Research Fellow - Software, Center for Computational Quantum Physics

About the Role

Directed by Antoine Georges and co‑directed by Andrew Millis, the Center for Computational Quantum Physics (CCQ) at the Flatiron Institute is a leading international center for the study of equilibrium and non‑equilibrium many‑body quantum systems. The Flatiron Research Fellow‑Software position is a postdoctoral role focused on the design and implementation of scientific software that supports CCQ’s research programs, including major open‑source libraries such as TRIQS, AFQMC, and ITensor.

The appointment is initially for two years, with the possibility of a third‑year renewal based on performance. The position is based in New York City, with a principal office at the foundation’s offices, and may be eligible for subsidized housing within walking distance of CCQ. Anticipated start date is between late August 2027 and early November 2027.

Responsibilities

• Develop, implement, maintain, and support scientific software, contributing to one or more existing CCQ code bases.
• Perform theoretical and computational research related to many‑body quantum systems.
• Assist in organizing CCQ and Flatiron‑wide collaborative activities, including seminars, workshops, and meetings.
• Participate actively in the preparation of manuscripts and conference presentations.
• Mentor undergraduate and graduate students as appropriate.
• Share expertise and provide training and guidance to CCQ staff and visitors.

Minimum Qualifications

• Ph.D. in a relevant field (e.g., theoretical condensed matter physics, computational physics, materials science, theoretical or computational chemistry, applied mathematics, computer science).
• Demonstrated expertise in software and algorithm development, computational methods, data analysis, modeling, machine learning, high‑performance and parallel computing, or scientific simulation.
• Proficiency with modern programming languages such as C++, Python, or Julia.
• Ability to conduct independent research and collaborate effectively in a team environment.
• Effective oral and written communication skills.

Compensation and Benefits

The full‑time annual compensation for this position is $95,000. In addition to the salary, the Simons Foundation provides an outstanding benefits package.
