Position Summary

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.

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

Required Qualifications:

• 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

Preferred Qualifications:

• 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

COMPENSATION AND BENEFITS

• The full-time annual compensation for this position is $75,000.
• In addition to competitive salaries, the Simons Foundation provides employees with an outstanding benefits package.
