AWS Trainium / NKI Kernel Expert

Anyone AI

Responsibilities

  • You’ll review and evaluate technical tasks involving:
  • NKI kernel correctness and Trainium-specific development patterns
  • CUDA → NKI kernel migrations
  • Trainium performance optimization and benchmarking
  • Memory management across SBUF, PSUM, and HBM
  • Cross-platform numerical correctness between CUDA/Triton and NKI
  • Trainium-specific performance bottlenecks and optimization opportunities
  • Technical feedback and quality assessment of kernel implementations
  • The work involves determining whether implementations are not only technically correct, but also
  • idiomatic and optimized for Trainium hardware

Requirements

  • 2+ years of hands-on experience

Preferred

  • Experience with the
  • AWS Neuron SDK or Neuron Compiler
  • CUDA or Triton kernel development experience
  • Knowledge of NeuronCore-v2 architecture
  • Experience with FP32, BF16, FP8, and INT8 workloads
  • Experience benchmarking workloads on
  • Trn1 or Trn2 instances

What You’ll Work On

Tile-based computation and DMA scheduling rather than simply translated from GPU-based approaches.

What We’re Looking For

developing or optimizing kernels with the Neuron Kernel Interface (NKI)

Experience working with

AWS Trainium and/or Inferentia2

Strong understanding of

  • Tile-based computation
  • SBUF / PSUM / HBM memory hierarchy
  • Partition dimension constraints
  • DMA orchestration
  • Trainium-specific optimization techniques
  • Ability to evaluate
  • CUDA → NKI migrations

Experience profiling and optimizing workloads on Trainium

  • Understanding of numerical differences across GPU and Trainium backends
  • Strong ability to analyze complex technical implementations and provide clear written feedback

Nice to Have

Familiarity with

nki.language

  • @nki.jit, or XLA custom calls
  • Experience with technical evaluation, AI/ML data projects, RLHF, or rubric-based assessment
  • Engagement

Engagement

Part-time, project-based consulting

Focus

  • AWS Trainium / NKI kernel engineering and technical evaluation
  • This is a strong fit for engineers who have worked deeply with
  • AWS Trainium infrastructure and low-level ML kernel optimization and are interested in applying that expertise to technically challenging AI projects.
