We build the fastest GPU compiler in the world. Most compilers have to preserve correctness at every transform, constraining how far they can search, while we prove correctness at the end instead, allowing us to search a far wider space, with agents, with RL, with anything that works and still guarantee the result. It’s why we hold #1 on NVIDIA’s own kernel benchmark across hundreds of production kernels.
We’re hiring a Member of Technical Staff for GPU Kernel Engineering to establish and push the envelope on what the hardware can actually do before any search ever runs. To this extent, you’ll write and hand-optimize kernels that execute during pre-training, post-training and inference, across NVIDIA, AMD, TPU and Trainium. You’ll then take those learnings and convert them into structures the compiler can search: instruction sequences, scheduling strategies, cost signals, to ensure that the ceiling you worked for by hand can become the floor for the search finding kernels everywhere else.
You’ll have access to better tooling than anywhere else because we own the stack all the way down to the ISA, allowing us to create kernels that others can’t even express. For example, our custom LLVM backend emits cubins directly, without a PTX handoff or ptxas doing our scheduling, letting us write kernels that have no expression in CUDA at all. Our team understands the hardware better than anyone else, to this extent we’ve built a bit-exact software model of Blackwell’s tcgen05.
You’ll be writing kernels that ship immediately on runs such as pre-training AlphaFold v3 at 3.4× the throughput, post-training robotics models on Trainium or running our custom RL rollout engine on TPU at multi-100B parameter scale.
