About the Team

Our mission at OpenAI is to discover and enact the path to safe, beneficial AGI. The team builds the performance-critical systems that allow OpenAI's models to run efficiently across a diverse set of AI accelerators.

About the Role

As a Software Engineer, Trainium, you will help bring OpenAI's inference workloads to AWS Trainium and build the software stack required to run cutting-edge frontier models efficiently on the platform. This is a deeply technical, cross-stack role spanning kernels, compilers, and model execution.

In This Role, You Will

  • Build and optimize OpenAI's inference stack for AWS Trainium.
  • Develop high-performance kernels for critical model operations and workloads.
  • Extend and improve compiler support to efficiently target Trainium hardware.
  • Build the systems necessary to execute and optimize the model forward pass on Trainium.
  • Profile workloads and identify bottlenecks across kernels, compiler-generated code, runtime, and model execution.
  • Partner with inference and ML systems teams to bring new models and architectures onto Trainium.
  • Work across the hardware/software boundary to unlock performance and capabilities from specialized AI accelerators.
  • Own complex performance and systems problems end-to-end, from investigation through production deployment.

We're Looking for a Track Record Of

  • 3+ years of relevant engineering experience, ideally in ML systems, compilers, kernels, runtimes, or performance engineering.
  • Strong systems programming fundamentals and experience writing performance-critical software.
  • Experience working with GPU, TPU, Trainium, or other specialized accelerator architectures.
  • Ability to reason about performance across multiple layers of the stack, from hardware and kernels through compilers and ML frameworks.
  • Owning technically ambiguous problems end-to-end and learning new hardware and software domains as needed.
