Genesis-World: Core Simulation Engine Engineer
About The Position
Genesis-World is an open-source, general-purpose simulation platform for physical AI from Genesis AI. It features a unified multi-physics engine supporting rigid bodies, FEM, MPM, particles, cloth, and fluids, along with an advanced real-time renderer, Nyx, and comprehensive sensor simulation, including advanced tactile simulation. The platform is Python-first, runs on various hardware, and utilizes an in-house JIT compiler, Quadrants, to target multiple GPU and CPU architectures. Genesis-World aims to accelerate robotics development by providing a simulation environment that runs significantly faster than real hardware and correlates well with on-hardware results, enabling physical AI to improve at the speed of compute.
Requirements
- Strong Python engineering skills 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 to reason about compilation caching, kernel dispatch, and startup cost.
- Comfort debugging across a full platform matrix: Windows, Linux, and macOS, on x86 and arm64, over CUDA, AMD, and Apple Metal.
- Experience with open-source practices: triaging issues, reviewing external pull requests, and communicating with a community.
- An understanding of physics and robotics to grasp the workings and usage of a simulation platform like Genesis-World.
Nice To Haves
- Experience with other robotics simulators (Drake, MuJoCo, Newton, Isaac, RaiSim, Jiminy, Brax).
- Experience with PyTorch.
- Experience with other JIT compilers such as Triton, JAX, or Numba.
- Experience with 3D tooling and interactive editors (Maya, Blender, Houdini).
- Familiarity with serialization formats (USD, glTF, MJCF/URDF).
- Experience with C++, CUDA, or Metal.
- Experience in developer relations or community work.
Responsibilities
- Build the software engineering backbone of Genesis-World to ensure reliability, maintainability, and a frictionless user experience.
- Act as a core maintainer of Genesis-World, with shared stewardship of the entire platform.
- Collaborate with the physics team to enhance the infrastructure, tooling, APIs, and architecture surrounding their algorithms.
- Address challenges in making JIT-compiled engine testing scalable.
- Develop solutions to make any bug reproducible, including bit-exact simulation dumps and automatic generation of standalone reproduction scripts.
- Enhance the first-class support for autodiff, working closely with the compiler team.
- Develop features for editing scenes at frozen time, enabling instant iteration on layout without full build cycles.
- Make the simulator extensible through first-class plugins for physics solvers and interactive viewer backends.
- Implement clean abstractions for motors and MIMO transmissions at the interface between users and the physics engine.
- Modify the engine to make time a local variable, allowing for independent environment stepping and adaptive timesteps.
- Implement events triggered by physics to make scenes more dynamic.
- Refactor legacy subsystems, strengthen typing, enforce consistent coding style, reduce Python overhead on hot paths, implement full scene serialization, and improve telemetry and replay.
- Review issues and pull requests with the core team.
- Answer questions from users and contributors.
- Participate in adoption efforts.
