Anyone AI is recruiting experienced GPU Kernel Engineers for a specialized project focused on reviewing, debugging, and evaluating high\-performance compute kernels used in AI workloads.

We’re looking for engineers with hands\-on experience writing and optimizing kernels across frameworks such as CUDA, Triton, NKI, or Pallas, with a strong understanding of numerical correctness, GPU performance, memory optimization, and benchmarking.

What You’ll Work On
-----------------------

You’ll work with GPU and accelerator kernel tasks involving:

  • Kernel implementation and debugging

  • CUDA and Triton optimization

  • Translation between kernel frameworks

  • Hardware migration

  • Operator fusion

  • Performance profiling and benchmarking

  • Numerical correctness verification

  • Compilation and runtime debugging

  • Memory hierarchy optimization

  • Kernel\-level AI workload performance
You’ll assess whether implementations are technically correct, efficiently designed, reproducible, and appropriately optimized for the target hardware.

What We’re Looking For
--------------------------

  • 3\+ years of hands\-on experience developing, optimizing, or debugging GPU or accelerator kernels

  • Strong experience with at least two of the following:
+ CUDA
+ Triton
+ NKI / AWS Neuron
+ Pallas / JAX
  • Strong understanding of GPU performance optimization

  • Experience with kernel profiling tools such as Nsight, NCU, roofline analysis, or framework\-native profilers

  • Understanding of:
+ Memory bandwidth
+ Compute throughput
+ GPU occupancy
+ Shared memory
+ Register pressure
+ Memory coalescing
+ Bank conflicts
  • Strong understanding of floating\-point numerical correctness and tolerance thresholds

  • Experience debugging kernel compilation and runtime issues

  • Ability to distinguish software defects, environment problems, and genuine optimization challenges
Relevant Experience
-----------------------

Candidates should have experience with several of the following types of work:

  • Writing kernels from technical specifications

  • Translating kernels between CUDA, Triton, or other frameworks

  • Migrating kernels across hardware platforms

  • Debugging incorrect kernel implementations

  • Optimizing kernel performance

  • Fusing multiple operations into optimized kernels
Nice to Have
----------------
  • Experience across both NVIDIA GPU and custom accelerator ecosystems

  • Experience with AWS Trainium, TPU, JAX, or other accelerators

  • Compiler engineering experience

  • Familiarity with MLIR, XLA, or intermediate representation lowering

  • Contributions to GPU or ML kernel libraries

  • Experience with cuBLAS, cuDNN, Triton community kernels, or JAX/XLA custom calls

  • Experience with AI model evaluation, RLHF, or technical benchmark development
What You’ll Be Responsible For
----------------------------------
  • Reviewing GPU and accelerator kernel implementations for correctness

  • Comparing outputs against reference implementations

  • Evaluating numerical tolerance thresholds

  • Reviewing kernel benchmarks and determining whether comparisons are fair

  • Identifying performance bottlenecks and optimization opportunities

  • Assessing whether performance targets are realistic given hardware limits

  • Reviewing kernel translations and hardware migrations

  • Identifying compilation, driver, memory, shape, and runtime issues

  • Determining whether technical tasks are genuinely difficult or incorrectly configured

  • Providing clear, actionable technical feedback
Engagement
--------------

Work Type: Remote

Engagement: Part\-time, project\-based consulting

Focus: GPU kernels, performance engineering, debugging, and technical evaluation

This role is ideal for engineers who enjoy working close to the hardware, optimizing GPU workloads, debugging low\-level performance issues, and pushing AI compute systems toward their performance limits.
