About the Role

You will push the physics of Genesis-World forward, shipping production-ready simulation capabilities that matter for the company's internal needs. This involves applied research from algorithm to merged, tested, documented code that real robot-learning pipelines depend on, with occasional groundbreaking research through academic collaborations. The core of the job is making the engine measurably better across five axes: Speed, Completeness, Fidelity, Versatility, and Scalability.

Responsibilities

Ship production-ready simulation capabilities that matter for the company's internal needs.
Conduct applied research from algorithm to merged, tested, documented code.
Make the engine measurably better across speed, completeness, fidelity, versatility, and scalability.
Invent physics level-of-detail (LOD).
Develop solutions for heterogeneous environments.
Implement adaptive timesteps per island.
Couple everything efficiently and accurately.
Develop more scalable constraint solvers.
Unify contact resolution.
Handle closed kinematic loops without constraints.
Write physics in plain Python and ensure Quadrants makes it fast on every backend.
Validate physics through analytical closed forms, other engines, and real-world data.

Requirements

A physicist and an engineer at once.
Ability to judge a method by its production viability at real scale.
Relentlessly hunt down insignificant defects.
A strong background in physics-based simulation, preferably related to robotics: RBD, FEM, MPM, SPH, IPC, XPBD, VBD, ABD, plus constrained optimization and numerical integration of stiff systems.
A track record of shipping simulation code that others rely on, in an engine, in industry, or in a research codebase used beyond its authors.
Solid HPC programming (CPU and/or GPU).
An instinct for what makes a numerical method fast in practice, beyond complexity classes.
Rigor in validation: analytical closed forms, cross-engine consistency, real-world data.
Publications in simulation, graphics, or robotics venues (SIGGRAPH, ICRA, IROS, CoRL, RSS) are a plus.
Contributions to an open-source physics engine are a plus.

About the Company

Genesis AI is building Genesis-World, an open-source, general-purpose simulation platform for physical AI.
Genesis-World features a unified multi-physics engine supporting rigid bodies, FEM, MPM, particles, cloth, and fluids.
The platform includes an in-house renderer, Nyx, for real-time photorealistic rendering.
It supports a wide range of sensors and advanced tactile simulation.
The engine is powered by an in-house JIT compiler, Quadrants, which optimizes code for various backends including CUDA, AMD ROCm, Apple Metal, Vulkan, x86, and ARM64.
Genesis-World is designed for massively batched GPU simulation for learning at scale and complex non-batched scenes.
The platform is central to Genesis AI's strategy to overcome the evaluation bottleneck in scalable robotics.
The goal is to establish Genesis-World as the go-to simulator for physical AI.
