About The Position

The Research Analyst in the Center for Computational Quantum Physics and Center for Computational Mathematics will optimize core numerical libraries that serve as foundational building blocks for scientific applications at the Flatiron Institute. The role focuses on improving performance, portability, and hardware utilization across three key libraries—NDA, PVFMM/DMK, and FINUFFT—as well as performance improvements in codes directly relevant to scientific applications.

Requirements

Proficiency in modern C++ (templates, compile-time programming, concepts)
Understanding of CPU architecture (SIMD instruction sets, cache hierarchy, memory layout)
Experience with performance analysis and benchmarking
Basic linear algebra background
Familiarity with Git-based workflows and CI/CD systems

Nice To Haves

Experience with SIMD intrinsics or vectorization libraries
Exposure to GPU programming (CUDA and/or HIP)
Familiarity with reduced-precision floating-point formats (FP16, BF16)
Understanding of FFT algorithms

Responsibilities

Establish automated CI-based performance tracking and regression detection for NDA
Implement reduced-precision floating-point support (FP16, BF16, FP8)
Tune SIMD vectorization dispatch and extend support for general memory layouts and complex types
Implement expression tree optimization and lazy evaluation for improved SIMD utilization
Develop GPU kernels (CUDA/HIP) for pair potential evaluation in PVFMM/DMK
Create parameter auto-selection heuristics and architecture-specific dispatch for FINUFFT
Explore optimization opportunities within TRIQS CTQMC and DiagMC codes
