Summary

In this role, you will be a member of the AI Networking Software team and part of the bigger DC networking organization. The team develops and owns the software stack around NCCL (NVIDIA Collective Communications Library), which enables multi-GPU and multi-node data communication through HPC-style collectives. NCCL has been integrated into PyTorch and is on the critical path of multi-GPU distributed training.

In other words, nearly every distributed GPU-based ML workload in Meta Production goes through the SW stack the team owns. At the high level, the team aims to enable Meta-wide ML products and innovations to leverage our large-scale GPU training and inference fleet through an observable, reliable and high-performance distributed AI/GPU communication stack. Currently, one of the team’s focus is on building customized features, SW benchmarks, performance tuners and SW stacks around NCCL and PyTorch to improve the full-stack distributed ML reliability and performance (e.g. Large-Scale GenAI/LLM training) from the trainer down to the inter-GPU and network communication layer.

And we are seeking for engineers to work on the space of GenAI/LLM scaling reliability and performance.

Responsibilities
  • Tech‑leading the collective communication library development on Meta’s large‑scale GPU training infra with a focus on GenAI/LLM scaling
  • Minimum Qualifications
  • Bachelor’s degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
  • Proven C/C++ and Python programming skills
  • Proven track record of leading successful projects
  • Effective leadership and communication skills
  • Specialized experience in one or more of the following machine learning/deep learning domains:
    Distributed ML Training, GPU architecture, ML systems, AI infrastructure, high performance computing, performance optimizations, or Machine Learning frameworks (e.g. PyTorch)
  • Preferred Qualifications
    • Experience with NCCL and distributed GPU performance analysis on RoCE/Infiniband
    • PhD in Computer Science, Computer Engineering, or relevant technical field
    • Knowledge of GPU architectures and CUDA programming
    • Knowledge of ML, deep learning and LLM
    • Experience with both data parallel and model parallel training, such as Distributed Data Parallel, Fully Sharded Data Parallel (FSDP), Tensor Parallel, and Pipeline Parallel
    • Experience in HPC and parallel computing
    • Experience working with DL frameworks like PyTorch, Caffe2 or Tensor Flow
    • Experience in AI framework and trainer development on accelerating large-scale distributed deep learning models
    Compensation

    $183,997/year to $257,000/year + bonus + equity + benefits
