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.

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 tool chains.

• 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.
• 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 3
  
  DEXPERIENCE, 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.
• Digital Twin Development: Knowledge of development tools and activities; ability to produce software products or systems in line with product requirements.
• Conduct walkthroughs and monitor effectiveness and quality of the development activities.
• Elaborate on multiple‑development toolkits for traditional simulation and digital twins.
• Have participated in development of multiple or large digital twins development.
• Contrast advantages and drawbacks of different development languages and tools.
• Estimate and monitor development costs based on functional and technical requirements.
• Provide consulting on both selection and utilization of developers' workbench tools.

• Communicating Complex Concepts: 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.
• 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.
• Managing Multiple Priorities: 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.
• Strategic Thinking: Knowledge of the importance of “big picture” thinking and planning; ability to apply organizational acumen and competitiveness to identify and maintain focus on key success factors.
• Influencing Through Expertise: Knowledge of effective influencing tactics and strategies; ability to use these to deepen expertise and impact or challenge decisions within and outside the organization.

• Simulation Development: Develop the simulation logic and behavioral models governing machine and system behavior.
• Real-Time 3D Visualization & Omniverse Engineering: Create…
