As a Software Engineer, you will help build AI systems that achieve levels of performance that were previously impossible. This means strong engineering fundamentals—designing and optimizing core ML systems, writing highly reliable low-level code, and advancing the algorithms and infrastructure that power our models. The end goal in every project is the same: push the frontier forward. The Compiler/Kernels team is responsible for the performance-critical software stack that brings OpenAI’s custom silicon to life. We design and build the compilers, languages, and high-performance kernels that allow researchers to fully exploit our first-party accelerators. This includes advancing Triton and its backend, developing new compiler passes, and creating the tooling needed to write fast, correct, and deeply optimized kernels for brand-new hardware. We partner closely with the hardware team to unlock new capabilities and ensure our custom silicon can support the next generation of frontier models.
