Join NVIDIA DevTech to profile, analyze, and optimize GPU-accelerated energy workloads (seismic processing, reservoir simulation, power grid simulation). Responsibilities include CUDA kernel and memory optimization, multi-GPU/multi-node scaling (MPI+NCCL), building benchmarks and reference implementations, and supporting customer engagements. Requires 5+ years in GPU/HPC optimization and strong C/C++ and Python skills on Linux.
