## About the role

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.

## What they're looking for

- Someone with a strong background in reinforcement learning with hands-on experience training agents
- Someone with experience building LLM agents, tool use and other agentic systems
- Someone with familiarity in GPU programming concepts and a willingness to get down to the ISA
- Someone proficient in PyTorch or JAX
- Someone with the ability to design and run experiments that produce trustworthy results
