High Performance Computing Intern

High Performance Computing Intern

The Scientific Computing Core (SCC) manages supercomputing resources and provides high performance computing (HPC) expertise to all centers at the Flatiron Institute, developing tools broadly useful to the scientific community as a whole.

The intern will work on a project at the intersection of astronomy and high-performance computing. The project will be selected based on the intern's skills and interests, but possible directions include:

• Development of a Python software package with a compiled, parallelized backend to compute the two-point correlation function using SIMD CPU acceleration;

• Development of a Python package leveraging the Flatiron Institute Non-Uniform Fast Fourier Transform (FINUFFT) to accelerate measurement of the cosmological power spectrum;

• Contributing to the development of C++ exascale cosmological N-body simulation software.

In addition to the project work, the intern may perform other duties or tasks as assigned or required.

The internship will take place in-person at the Simons Foundation’s offices in New York City from June 1, 2026 – August 14, 2026.

Applicable travel assistance to New York City and a supported temporary housing option while in New York City may be available.
