About the job
Optimizes inference for visual and other large models by improving GPU performance, model execution, and deployment efficiency.
What you'll do
- Profile model architectures and workloads to identify performance bottlenecks and measure optimization results.
- Develop inference optimizations, including algorithmic improvements and GPU kernels, across single-GPU, multi-GPU, and multi-node systems.
- Build benchmarking and profiling infrastructure, evaluate runtimes and hardware, and help deploy research models efficiently at scale.
What they ask for
- Deep technical ability in efficient ML inference, ML systems, GPU computing, or adjacent research, demonstrated through relevant work.
- Strong understanding of deep learning execution on hardware, including compute, memory, communication, and performance.
- Experience profiling ML workloads, identifying bottlenecks, and delivering measurable performance improvements.
- Strong programming fundamentals in Python, C++, or another systems-oriented language; experience with some combination of PyTorch, CUDA, Triton, TensorRT, vLLM, SGLang, or comparable technologies.
Nice to have
- Experience optimizing large generative, multimodal, vision, or video models.
- GPU kernel development, GPU architecture, inference optimization, model compilation, or multi-GPU/multi-node execution experience.
Tools
Python, C++, PyTorch, CUDA, Triton, TensorRT, vLLM, SGLang
