Senior Research Engineer- Performance Optimization
Palo Alto, California
Engineering /
Full Time /
On-site
We are looking for engineers with significant problem solving experience in PyTorch, CUDA and distributed systems. You will work with Research Scientists to build & train cutting edge foundation models on thousands of GPUs.
Responsibilities
- Ensure efficient implementation of models & systems for data processing, training, inference and deployment
- Identify and implement optimization techniques for massively parallel and distributed systems
- Identify and remedy efficiency bottlenecks (memory, speed, utilization) by profiling and implementing high-performance CUDA, Triton, C++ and PyTorch code
- Work closely together with the research team to ensure systems are planned to be as efficient as possible from start to finish
- Build tools to visualize, evaluate and filter datasets
- Implement cutting-edge product prototypes based on multimodal generative AI
Experience
- Experience training large models using Python & Pytorch, including practical experience working with the entire development pipeline from data processing, preparation & data loading to training and inference.
- Experience optimizing and deploying inference workloads for throughput and latency across the stack (inputs, model inference, outputs, parallel processing etc.)
- Experience with profiling CPU & GPU code in PyTorch, including Nvidia Nsight or similar.
- Experience writing & improving highly parallel & distributed PyTorch code, with familiarity in DDP, FSDP, Tensor Parallel, etc.
- Experience writing high-performance parallel C++. Bonus if done within an ML context with PyTorch, like for data loading, data processing, inference code.
- Experience with high-performance Triton / CUDA and writing custom PyTorch kernels. Top candidates will be able to utilize tensor cores; optimize performance with CUDA memory and other similar skills.
- Good to have experience working with Deep learning concepts such as Transformers & Multimodal Generative models such as Diffusion Models and GANs.
- Good to have experience building inference / demo prototype code (incl. Gradio, Docker etc.)
- Please note this role is not meant for recent grads.
