About the job

Designs, implements, and maintains high-performance kernels to improve throughput and latency for training and inference, especially for long-context workloads.

What you'll do

  • Design, implement, deploy, and maintain kernels, with responsibility for production reliability and correctness.
  • Optimize kernel performance for long-context behavior, including memory utilization, data movement, and sustained throughput.
  • Evaluate porting kernels to alternative hardware and co-design with training, inference, and RL teams.

What they ask for

  • Low-level programming experience targeting AI accelerators such as NVIDIA Blackwell or Google TPUs.
  • Experience developing and optimizing GPU kernels using frameworks such as NCCL, MSCCLPP, CUTLASS, CuTeDSL, Triton, Quack, or Flash-Attention.
  • Deep expertise in computer architecture, low-level machine optimizations, and code generation.

Nice to have

  • Experience with Pallas, Mosaic, or Mojo.
  • Breadth across machine learning.
