Design, build, and optimize distributed PyTorch training systems for multi-node GPU clusters. Profile and eliminate performance bottlenecks across data pipelines to GPU kernels, implement low-level CUDA/cuDNN/Triton kernels, tune CPU/GPU/memory/network utilization, and develop monitoring and debugging tools for large-scale training runs.
The summary above was generated by AI
What You’ll Do
  • Drive down wall-clock time to convergence by profiling and eliminating bottlenecks across the foundation model training stack stack, from data pipelines to GPU kernels

  • Design, build, and optimize distributed training systems (PyTorch) for multi-node GPU clusters, ensuring scalability, robustness, and high utilization

  • Implement efficient low-level code (CUDA, cuDNN, Triton, custom kernels) and integrate it seamlessly into high-level training frameworks

  • Optimize workloads for hardware efficiency: CPU/GPU compute balance, memory management, data throughput, and networking

  • Develop monitoring and debugging tools for large-scale runs, enabling rapid diagnosis of performance regressions and failures

What You’ll Bring
  • Deep experience in distributed systems, ML infrastructure, or high-performance computing (8+ years)

  • Production-grade expertise in Python

  • Low-level performance mastery: CUDA/cuDNN/Triton, CPU–GPU interactions, data movement, and kernel optimization

  • Scaling at the frontier: experience with PyTorch and training jobs using data, context, pipeline, and model parallelism

  • System-level mindset with a track record of tuning hardware–software interactions for maximum utilization
