Core Simulation Engine Engineer

• Build the software engineering backbone of Genesis-World, making the simulation codebase reliable, maintainable, and frictionless


• Serve as a core maintainer with shared stewardship of the whole platform


• Scale testing for a JIT-compiled engine and reduce compilation bottlenecks


• Make simulation bugs reproducible through bit-exact dump/reload across machines and backends


• Automatically generate standalone reproduction scripts from failing runs


• Make autodiff first-class by driving requirements for engine and compiler integration


• Enable editing of scenes at frozen time without rebuilding scenes or compiling the engine


• Create extensible plugins for physics solvers and interactive viewer backends, including Nyx


• Develop clean abstractions for motors and MIMO transmissions


• Decentralize simulation clocks and timesteps to the sub-scene level


• Implement physics-triggered events and interactions


• Refactor legacy subsystems, strengthen typing, standardize coding style, reduce Python overhead, and improve serialization, telemetry, and replay


• Review issues and pull requests with the core team


• Answer questions from users and contributors


• Support adoption of Genesis-World

Requirements

• Strong Python engineering on large codebases, including architecture, refactoring, typing, packaging, and performance profiling


• Experience with developer tooling, test infrastructure, or CI at scale


• Fluency with JIT compilation, code generation, or GPU computing stacks sufficient to reason about compilation caching, kernel dispatch, and startup cost


• Comfort debugging across Windows, Linux, and macOS, on x86 and ARM64, over CUDA, AMD, and Apple Metal


• Open-source experience, including triaging issues, reviewing external pull requests, and communicating with a community


• Comfort with physics and robotics and an understanding of how a simulator such as Genesis-World works and is used


• Opinions about API design


• Bonus: experience with Drake, MuJoCo, Newton, Isaac, RaiSim, Jiminy, or Brax


• Bonus: PyTorch, Triton, JAX, or Numba


• Bonus: 3D tooling and interactive editors such as Maya, Blender, or Houdini


• Bonus: serialization formats such as USD, glTF, MJCF, or URDF


• Bonus: C++, CUDA, or Metal


• Bonus: developer relations or community work

Core Competencies
