# Software Engineer, AI Tooling

What MatX is Building MatX's mission is to make the world’s best AI models run as efficiently as allowed by physics, bringing the world years ahead in AI quality and availability. We build custom silicon for training and running the world's largest AI models, with hardware/software co-design across ISA, RTL, simulator, compiler, and kernels. The AI tooling team sits across that whole stack and owns the agent harnesses and shared workflows that turn general-purpose coding agents into ones maximally useful on each layer. About the position Frontier agents are stronger on our Rust and Python than on our Bluespec and SystemVerilog. What context, tools, and checks make an agent trustworthy on a testbench or a timing report, and how do you know? Very few people anywhere have worked through these questions on a chip that has to tape out, with the engineers who sign off on it working next to them. You'd work side-by-side with our hardware engineers, learn how RTL design, design verification (DV), and physical design (PD) work here, codify what's already working, and build what's missing. What You'll Do Here: Close the gap where agents are worst at hardware engineering work. Pair with RTL,
