About the role
- The Simulation & Digital Twin Engineer will design, develop, and integrate simulation and visualization capabilities that support Caterpillar's next‑generation digital twin, machine behavior modeling, and interactive 3D experiences.
- This role combines simulation engineering, real‑time visualization, and 3D scene‑building using NVIDIA Omniverse and modern C++/Python toolchains.
- The engineer will build the behavioral logic, physics integrations, and visualization layers that enable accurate, high‑performance representations of Caterpillar machines, job sites, and workflows.
Responsibilities
- Simulation/Digital Twin Development: Develop and deploy the simulation logic and behavioral models governing machine and system behavior.
- Implement real‑time simulation algorithms, including kinematics, dynamics, and control‑system interactions.
- This includes integration of physics engines (e.g., PhysX, Omniverse Physics, or equivalent) to support realistic behavior and machine-environment interactions.
- Simulation Quality: Develop and execute model validation and verification plans, ensuring digital twins are accurate and numerically stable.
- Real‑Time 3D Visualization Engineering: Create high‑fidelity 3D models, scenes, and environments such as NVIDIA Omniverse.
- Develop interfaces that connect simulations to real‑time visualization, dashboards, and operator‑focused experiences.
- Implement automated test pipelines and document model correlations, limitations, and validation scoring.
- Integration & Platform Engineering: Contribute to toolchain and pipeline design, including scripting utilities, automated test frameworks, and modular code libraries.
- Collaborate across data engineering/architecture, autonomy, product groups, and engineering to ensure interoperability and alignment with business needs.
- Digital Twin Tooling & Ecosystem Support: Evaluate and implement new simulation libraries and real‑time rendering technologies that enhance simulation fidelity and performance.
Requirements
- Knowledge of technical aspects of simulation products
- Bachelor's degree in Computer Science, Software Engineering, Mechanical Engineering, Robotics, or a related field or equivalent experience.
- 5+ years of experience developing digital twins or simulation‑based systems in industries such as technology, aerospace, defense, heavy machinery, or automotive, with exposure to high‑fidelity modeling, physics‑based simulation, and real‑time visualization.
- Experience with NVIDIA Omniverse, including USD workflows, Omniverse Kit/Code, PhysX, or Omniverse‑based pipeline development.
- Experience with cloud‑based simulation workflows, large‑scale data integration, or distributed simulation pipelines.
