## Description

The Simulation & Digital Twin Engineer will design, develop, and integrate simulation capabilities that support Caterpillar's next-generation of robotics. This role combines simulation engineering, real-time visualization, and 3D scene-building using NVIDIA Omniverse and modern C++/Python toolchains. This is a senior hands-on role which will plan, architect and lead and mentor., * Develop simulation for construction machines, jobsites and sensors (Camera, LIDAR, RADAR etc.) in NVIDIA Omniverse.

 * Integrate simulation components with current Caterpillar simulation models, data systems, and digital twin frameworks.
 * Create high-fidelity 3D models, scenes, and environments using NVIDIA Omniverse, USD, and Omniverse Kit-based pipelines.
 * Collaborate with the simulation and robotics teams to define and implement a simulation Omniverse based platform with existing simulation tools.
 * Contribute to toolchain and pipeline design, including scripting utilities, automated test frameworks, and modular code libraries.
 * Develop interfaces that connect simulations to real-time visualization, dashboards, and operator-focused experiences.
 * Ensure performance optimization for large-scale scenes, complex mechanical models, and multi-machine workflows.
 * Develop and execute model validation and verification plans, ensuring digital twins are accurate and numerically stable.
 * Active reduce the real to sim gap by comparing simulation outputs to real machine test data, telematics, and historical performance metrics.
 * Evaluate emerging tools and frameworks to expand Caterpillar's simulation and digital-twin capabilities.
