Member of Technical Staff, ML Systems

About the Role

Join an AI company building systems for training and serving image, video, and world-model workloads. You will improve performance across the stack, from GPU kernels to distributed training and inference engines.

What You'll Do

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

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

• Implement low-level optimizations with CUDA and Triton.

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

• Improve communication performance across GPUs and nodes using technologies such as NCCL, RDMA, InfiniBand, and RoCE.

• Build benchmarks and regression tests to preserve performance improvements in production.

• Collaborate on hardware-aware kernel, runtime, and model design.

What We're Looking For

• Two or more years of experience in deep learning training or inference systems, distributed systems, or related ML systems work.

• At least one year of recent, hands-on experience in ML systems or GPU performance engineering.

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

• Hands-on experience writing kernels for NVIDIA GPUs using CUDA, CUTLASS, Triton, or PTX.

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

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

• Experience with diffusion, video, image, or other multimodal workloads is relevant.
