About the role

  • Big, hard problems are what Path tackles every day, and our people are our greatest asset to get that job done.
  • Emulate robot trajectories both with and without physical models.

Responsibilities

  • Implement and validate physics-based sensor simulation models (structured light, depth, RGB, stereo, etc.) within platforms such as NVIDIA Isaac Sim, Blender or Unreal Engine, producing outputs that closely match real sensor behavior.
  • Build photorealistic scene rendering pipelines that account for sensor placement on the robot end-effector.
  • Develop synthetic data generation pipelines producing annotated ground-truth (point clouds, depth maps, segmentation masks) at scale.
  • Implement domain randomization strategies (lighting, material variation, sensor noise, viewpoint perturbation) to improve sim-to-real transfer for downstream perception models.
  • Collaborate with perception teams to ensure rendered outputs meet dataset requirements and write high-quality Python code.
  • Lead the design and validation of high-fidelity, photorealistic sensor render pipelines grounded in real sensor characterization data and validated against physical measurements.
  • Own the sim-to-real validation framework: define quantitative benchmarks and go/no-go criteria for when synthetic sensor data is ready to feed production model training.
  • Drive 3D asset and environment pipeline strategy, including CAD-to-simulation workflows, SDF/URDF asset management, material library management, and procedural scene generation for weld cell environments across Gazebo, Isaac Sim, and Unreal Engine.
  • Define strategy for when and how to use each simulation platform (Gazebo for ROS-integrated functional testing, Isaac Sim or Unreal Engine for photorealistic synthetic data generation) and build workflows that span them coherently.
  • Build the Path Forward

Requirements

  • Software Proficiency: Strong Python skills for building production-grade simulation tooling and plugins.
  • Simulation Platforms: Hands-on experience with NVIDIA Isaac Sim, Unreal Engine, Blender or Gazebo (Classic/Ignition).
  • Generative AI: Experience with generative image AI (e.g., diffusion models) and its application in synthetic data generation.
  • Architect the sensor rendering strategy for the Perception team, defining which sensor modalities, material models, and environmental conditions must be simulated to support perception across the full weld cell workflow.
  • Hands-on experience with NVIDIA Isaac Sim, Unreal Engine, Blender or Gazebo (Classic/Ignition).
  • Experience with generative image AI (e.g., diffusion models) and its application in synthetic data generation.
  • 3D data and assets: Experience with mesh representations, material authoring, and CAD-to-render workflows using formats such as URDF, SDF, or USD.

Nice to have

  • Familiarity with simulating industrial phenomena like arc flash, weld spatter, and thermal emission.
  • Experience with generative AI (diffusion models) and procedural geometry for scalable 3D mesh generation.
  • Prior work in manufacturing or automotive simulation and cloud-based render farm infrastructure.
  • Experience with GPU-accelerated rendering or cloud-based render farm infrastructure.
  • Why You'll Love It Here
  • Free lunch every day
  • 401K through Empower
  • We encourage unique thinking and are dedicated to creating a diverse and inclusive environment.

Skills

  • Mentor engineers on rendering best practices, physically based material modeling, Gazebo plugin development, and synthetic data methodology.

Compensation

  • Rendering & Assets: Solid understanding of Physically Based Rendering (PBR) and experience with 3D assets (URDF, SDF, USD).
