Job Description

About Genesis AI

Genesis AI builds the simulation platform powering the next generation of robotics and embodied AI. Our flagship product, Genesis World, is a unified multi-physics simulation engine paired with Nyx, our in-house GPU-accelerated, path-traced photorealistic renderer. Together they provide a platform for training robotics and embodied AI at scale; letting teams simulate complex physical worlds with high fidelity and speed, from a laptop to datacenter-grade GPUs, and close the gap between simulation and the real world.

About the Role

We're hiring a Senior QA Engineer to own quality across Nyx and the Genesis World engines. You'll split your time evenly between hands-on exploratory testing and enhancing our automated test infrastructure. Because both systems run on GPUs and underpin robotics training and scientific workloads, correctness goes beyond "does it run": it's about visual fidelity, numerical accuracy, determinism, and reproducibility across hardware.

We're especially looking for someone with strong knowledge of 3D environments, assets, and rendering, who can reason about what "visually and physically correct" actually means.

What You'll Do

  • Maintain and evolve our automated test suites for the Nyx renderer and the Genesis World physics engine.
  • Develop image-comparison / perceptual-diff tooling to catch rendering regressions, and validation harnesses to catch simulation drift.
  • Validate numerical correctness, determinism, and reproducibility across GPUs, drivers, and CUDA versions.
  • Perform exploratory and manual testing on 3D scenes, assets, and complex multi-physics scenarios that are hard to automate.
  • Set up quality gates in CI for prebuilt wheels across platforms (Linux, Windows, Python 3.10–3.13).
  • Triage, reproduce, and clearly document defects; partner with engineers on root cause.

What We're Looking For

  • 5+ years in software QA, with strong experience in both test automation and exploratory testing.
  • Solid 3D environment and asset knowledge, with familiarity with rendering and simulation/physics.
  • Strong Python and C++ skills; comfortable reading performance-sensitive code.
  • Understanding of testing challenges in GPU and floating-point systems; non-determinism, tolerance-based assertions, hardware/driver variance.
  • Experience building test infrastructure in CI/CD and managing cross-platform builds.
  • Excellent debugging instincts and clear, reproducible bug reports.

Nice to Have

  • Experience with GPU programming, or ray/path tracing concepts.
  • Background in computer graphics (PBR, color management, perceptual image metrics).
  • Familiarity with physics or scientific simulation.
  • Robotics or sim-to-real experience.

About Genesis AI

Genesis AI is a global full-stack robotics company building general-purpose robots with human-level intelligence and capabilities. Led by a world-class team obsessed with excellence at every level, Genesis AI is pushing the boundaries of robotics and AI to unlock a new era of human productivity.

We are a new generation of robotics builders, united by a shared mission to push the boundaries of physical AI. Our team brings together the minds behind many of the most significant advances in robotics and AI in recent years — spanning the full stack.

We introduced generative simulation, created foundational platforms such as Genesis, Jiminy, Flightmare, GVBD Voxels, and invented the IPC algorithm. We led the development of the first multimodal models at Mistral AI and Apple Intelligence. We co-created UMI and Diffusion Policy, pioneered reinforcement learning frameworks for superhuman drone racing, and scaled robotic data systems at NVIDIA GR00T. We built cross-platform GPU compilers such as VeriGPU, DeepCL, Coriander, and the original PyTorch. We also built industry-leading rendering engines at Google, Epic and Unity. Now, we’ve come together at Genesis AI to close the loop, and build what’s next.
