Member of Technical Staff, ML Systems

About the Role

Join a technical team building training and inference systems for image, video, and world-model workloads. You will improve performance across GPU kernels, distributed execution, and multi-node training and serving.

What You'll Do

• Optimize training and inference performance for image, video, and world-model workloads.

• Profile and remove bottlenecks at the kernel, memory, system, and cluster levels using Nsight and related tools.

• Implement low-level optimizations in CUDA and Triton.

• Design and improve distributed training and inference engines for diffusion models.

• Improve communication performance across GPUs and nodes using NCCL, RDMA, InfiniBand, RoCE, and disaggregated serving approaches.

• Build benchmarking and regression harnesses to preserve performance improvements in production.

• Co-design kernels, runtimes, and models with hardware considerations in mind.

What We're Looking For

• At least 2 years of experience in deep learning training or inference systems, or distributed systems, including at least 1 year of hands-on ML systems or GPU performance work in a recent role.

• Experience authoring core features in an inference or training framework, such as vLLM, SGLang, TensorRT-LLM, Megatron, or a similar system.

• Direct GPU kernel development experience with CUDA, CUTLASS, Triton, or PTX on NVIDIA GPUs.

• Experience with inference or training performance across GPU kernels, runtimes, or distributed execution.

• Strong computer science and machine learning fundamentals, with a degree in computer science or a related quantitative field.

• Experience optimizing diffusion, video, image, or other multimodal workloads is valuable.
