Senior Software Engineer (Simulation Platform)

Build next-generation digital twin and interactive 3D experiences at Caterpillar in Irving, TX (onsite). In this Senior Software Engineer role, you will design and deliver simulation and visualization capabilities that support Caterpillar’s digital twin initiatives, working primarily with NVIDIA Omniverse and modern C++/Python toolchains across modeling, validation, and integration.

What you’ll work on

• Develop simulation logic and behavioral models that represent machine and system behavior.
• Build high-fidelity 3D models, scenes, and environments using NVIDIA Omniverse, USD, and Omniverse Kit-based pipelines.
• Create and run model validation and verification plans to ensure digital twins are accurate and numerically stable.
• Integrate simulation components with Caterpillar models, data systems, and digital twin frameworks.
• Design and contribute to the toolchain and pipeline including scripting utilities, automated test frameworks, and modular code libraries.
• Work hands-on across multiple digital-twin platforms, including NVIDIA Omniverse (primary), CARLA, Siemens NX/Teamcenter/Plant Simulation, Dassault 3DEXPERIENCE, Ansys Twin Builder, or similar, plus Unity or Unreal Engine.
• Integrate data, models, or external simulation engines into unified digital-twin experiences.
