NVIDIA is looking for a passionate, world-class computer scientist to work in its Compute Developer Technology (DevTech) team. In this role, you will research and develop techniques to GPU-accelerate leading applications in high performance computing fields within machine and deep learning, scientific computing, and data processing, performing in-depth analysis and optimization to ensure the best possible performance on current- and next-generation GPU architectures.What you will be doing:Working directly with key application developers (especially LLM) to understand the current and future problems they are solving, creating and optimizing core parallel algorithms and data structures to provide the best solutions using GPUs, through both library development and direct contribution to the applications. This includes training and inference optimization for large language models, directly contributing to frameworks such as Megatron and TRTLLM, SGLang, vLLM...Collaborating closely with the architecture, research, libraries, tools, and system software teams at NVIDIA to influence the design of next-generation architectures, software platforms, and programming models, including by investigating impact on application performance and developer productivity.Engaging in deep optimization of high-performance operators, involving but not limited to CUDA deep optimization, instruction and compiler optimization. These optimizations will directly support customers or be integrated into products like cuDNN, cuBLAS, and CUTLASS...Some travel is required for conferences and for on-site visits with developers.What we need to see:A degree from university in an engineering or computer science related discipline (BS; MS or PhD preferred).2+ working experience is required.Strong knowledge of C/C++ and/or Fortran.Deep knowledge of software design, programming techniques, and algorithms.Expert knowledge of LLM training/inference optimization, including but not limited to development and optimization experience in distributed training/inference, NCCL, NVSHMEM, IB, RoCE, etc.Strong mathematical fundamentals, including linear algebra and numerical methods.Experience with parallel programming, ideally CUDA C/C++ and OpenACC.Good communication and organization skills, with a logical approach to problem solving, good time management, and task prioritization skills.With highly competitive salaries and a comprehensive benefits package, NVIDIA is widely considered to be one of the technology industry's most desirable employers. We have some of the most brilliant and talented people on the planet working with us and our engineering teams are expanding fast. If you're a creative and autonomous computer scientist with a genuine passion for parallel computing, we want to hear from you.
