Sr. Digital Twin Engineer

Caterpillar•Irving, TX

7d•Onsite

About The Position

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.

Requirements

Knowledge of effective presentation tools and techniques to ensure clear understanding; ability to use summarization and simplification techniques to explain complex technical concepts in simple, clear language appropriate to the audience.
Understanding of effective communication concepts, tools, and techniques; ability to effectively transmit, receive, and accurately interpret ideas, information, and needs through the application of appropriate communication behaviors.
Knowledge of effective self-management practices; ability to manage multiple concurrent objectives, projects, groups, or activities, making effective judgments as to prioritizing and time allocation.
Bachelor’s degree in computer science, Software Engineering, Robotics, or a related field.
Basic experience developing digital twins or simulation 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.
Hands-on programming skills in C++ and Python
Experience in validating simulation models and digital twins using test data correlation, scenario-based testing, regression testing, and telematics/real-world data.
Knowledge of 3D scene construction, rendering concepts, and UI development for real-time visualization.

Responsibilities

Develop the simulation logic and behavioral models governing machine and system behavior.
Create high-fidelity 3D models, scenes, and environments using NVIDIA Omniverse, USD, and Omniverse Kit-based pipelines.
Execute model validation and verification plans, ensuring digital twins are accurate and numerically stable.
Contribute to toolchain and pipeline design, including scripting utilities, automated test frameworks, and modular code libraries.
Work hands-on with multiple digital-twin platforms, such as NVIDIA Omniverse (primary environment), CARLA, Siemens NX/Teamcenter/Plant Simulation, Dassault 3DEXPERIENCE, Ansys Twin Builder, or similar, Unity or Unreal Engine.
Integrate data, models, or external simulation engines into unified digital-twin experiences.
