Sr. Digital Twin Engineer

Career Area:

Technology, Digital and Data

Job Description:

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.

What You Will Do:

• Simulation Development: Develop the simulation logic and behavioral models governing machine and system behavior.

• Real‑Time 3D Visualization & Omniverse Engineering: Create high‑fidelity 3D models, scenes, and environments using NVIDIA Omniverse, USD, and Omniverse Kit‑based pipelines.

• Validation & Testing of Models and Digital Twins: Develop and execute model validation and verification plans, ensuring digital twins are accurate and numerically stable.
• Integration & Platform Engineering: Integrate simulation components with current Caterpillar models, data systems, and digital twin frameworks. Contribute to toolchain and pipeline design, including scripting utilities, automated test frameworks, and modular code libraries.

What You Will Have:

• 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
• Digital Twin Tooling & Ecosystem Support:  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.
• Innovation & Technology Leadership: Assist in evaluating emerging tools and frameworks to expand Caterpillar’s simulation and digital‑twin capabilities

Top Candidate Will Have:

Decision Making and Critical Thinking: Knowledge of the decision-making process and associated tools and techniques; ability to accurately analyze situations and reach productive decisions based on informed judgment.

Effective Communications: 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.

Digital Twin Development: Knowledge of development tools and activities; ability to produce software products or systems in line with product requirements.

• Conducts walkthroughs and monitors effectiveness and quality of the development activities.
• Elaborates on multiple-development toolkits for traditional simulation and digital twins.
• Has participated in development of multiple or large digital twins development.
• Contrasts advantages and drawbacks of different development languages and tools.
