Lead Simulation Engr (Digital Twin)
About The Position
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. Help Build the Future of Caterpillar – Be Part of What’s Next in Autonomous Construction Sites At Caterpillar, technology always has a purpose, which is to solve our customers’ toughest challenges. Construction autonomy is one of the most complex challenges in applied AI, and at Caterpillar, advancements in physical AI, simulation, sensing, and edge computing are turning things that once felt impossible—intelligent machines operating in dynamic jobsites—into reality. Role Definition: 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.
Requirements
- Bachelor’s degree in Computer Science, Software Engineering, Mechanical Engineering, Robotics, or a related field.
- 5+ years of experience developing digital twins and simulations to support robotics. This includes machine, vehicle and/or sensor simulation.
- Experience with NVIDIA Omniverse, Isaac Sim, Cosmo, NVIDIA WARP, Newton, and Omniverse‑based pipeline development.
- Knowledge of other digital‑twin and real‑time simulation tools, such as CARLA, Unity, Unreal Engine, Siemens NX/Teamcenter/Plant Simulation, Dassault 3DEXPERIENCE, Ansys Twin Builder etc.
- Strong hands‑on programming skills in C++ and Python for simulation logic, behavior modeling, and tooling.
- Experience with cloud‑based simulation workflows, large‑scale data integration, or distributed simulation pipelines.
Responsibilities
- 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.
