Senior Performance Engineer
The Senior Performance Engineer joins the STG group within the AGI Lab to address complex system-level challenges for AI/ML workloads. This role involves building and operating representative AI environments, including agentic workflows, distributed inference systems, and MoE deployments. You will collect workload traces and performance data to identify bottlenecks across compute, memory, communication, and scheduling resources while evaluating how emerging workloads interact with accelerator architectures. The position requires proficiency in Python and C++, along with experience using Nsight Systems and Nsight Compute to optimize workloads on NVIDIA GPU platforms. Candidates must possess a deep understanding of LLM inference and training systems, as well as familiarity with frameworks like PyTorch, vLLM, SGLang, TensorRT-LLM, DeepSpeed, Ray, or Megatron-LM. You will collaborate on hardware-software co-design to improve the performance and scalability of next-generation AI infrastructure.
