About The Position

Your Work Shapes the World at Caterpillar Inc. When you join Caterpillar, you're joining a global team who cares not just about the work we do – but also about each other. We are the makers, problem solvers, and future world builders who are creating stronger, more sustainable communities. We don't just talk about progress and innovation here – we make it happen, with our customers, where we work and live. Together, we are building a better world, so we can all enjoy living in it. You’ll build and deploy against one of the most unique data foundations—over 1.6 million connected assets generating real-world data daily. These data and platform capabilities are enabling the development of AI models, edge computing architectures, and software systems that scale across fleets, products, and industries. The result will be a new generation of machines that continuously learn, improve, and deliver performance at scale. 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

Bachelor’s degree in Computer Science, Software Engineering, Robotics, or a related field.
3+ years of experience developing digital twins or simulation with exposure to high‑fidelity modeling, physics‑based simulation, and real‑time visualization.
Experience in system‑level simulation and digital twin technologies.
Experience with NVIDIA Omniverse, including USD workflows, Omniverse Kit/Code, PhysX, or Omniverse‑based pipeline development.
Strong 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.
