## About the role

Simulation is still a hard sell in robotics. Outside a few success stories, like reinforcement learning for locomotion, most teams skip it, and friction is a big part of why: painful to use, painful to debug. We live that pain ourselves: debugging a failing experiment during policy evaluation takes 30 minutes, and there is no way to automatically generate a standalone reproduction script. That blocks adoption, even internally.

## What they're looking for

- You care about the engineer using what you build as much as the thing itself. A slow test, a cryptic error, a manual step: you see it, you go after the root cause, and you remove it for everyone. You have opinions about API design
- You are comfortable with physics and robotics: the right design choices take a working picture of what a simulator like Genesis-World does, how it works, and how it is used, a picture you can partly build on the job
- Strong Python engineering on large codebases: architecture, refactoring, typing, packaging, performance profiling (py-spy, Nsight, Xcode Instruments, RenderDoc)
- Developer tooling, test infrastructure, or CI at scale
- Enough fluency with JIT compilation, code generation, or GPU computing stacks to reason about compilation caching, kernel dispatch, and startup cost. You will work closely with Quadrants
- At ease debugging across the full platform matrix: Windows, Linux, and macOS, on x86 and arm64, over CUDA, AMD, and Apple Metal (and possibly Intel XPU via Vulkan soon)
