EPAM Systems

hpc cuda optimization engineer

In short

This senior-level, fully remote role focuses on designing and optimizing CUDA kernels for large-scale scientific and engineering applications at EPAM Systems. It requires deep GPU computing expertise including CUDA, PTX, memory hierarchy optimization, and distributed/multi-GPU computing with MPI, NCCL, and NVSHMEM. The work involves high-performance C++ and Python development, GPU profiling, and debugging complex performance issues, with Oil & Gas domain experience (RTM/FWI, seismic imaging) considered a plus.
