Responsibilities

  • Build and improve model training services covering pre-training, post-training, and distillation.
  • Optimize distributed training compute, memory, communication, kernels, and execution across large GPU and TPU systems.
  • Diagnose complex performance problems, implement optimizations, and validate improvements.
  • Lead technical work across teams and communicate complex technical tradeoffs.
  • Design training APIs and frameworks, including trainer abstractions, configuration systems, and low-level training primitives.
  • Contribute to optimization and training-algorithm research, including new optimizers, hyperparameter transfer, and scaling-law studies.

Requirements

  • 8+ years of software engineering or ML systems experience, including several years of hands-on distributed training on hundreds or more accelerators.
  • Strong understanding of modern model architectures, particularly transformers, including model computation, memory requirements, and training-cost implications.
  • Hands-on experience with distributed training optimization using PyTorch Distributed, Megatron-Core, JAX/XLA, or equivalent systems.
  • Strong programming skills in Python plus C++, CUDA, Triton, or equivalent performance-oriented technologies.
  • Ability to independently diagnose complex performance problems, implement optimizations, and validate improvements.
  • Proven record of leading technical work across teams and clearly communicating complex tradeoffs.
  • BS, MS, or PhD in Computer Science, Machine Learning, or a related field, or equivalent practical experience.
  • Preferred experience with mixture-of-experts, expert parallelism, long-context models, advanced attention mechanisms, high-performance kernels, compilers, GPU and TPU architecture, distributed communication, and low-precision training such as FP8.
  • Preferred contributions to relevant open-source projects, experience designing training frameworks, optimization and training-algorithm research, and experience training recommendation, multimodal, or diffusion models at scale.
