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
