Job summary

Caterpillar Inc. is seeking a Simulation Engineer to build and scale the simulation engine for autonomous construction machines at their Irving, TX site.

You will develop the framework, orchestration, and scalability to support high-fidelity simulations of machines, jobsites, and sensors using NVIDIA Omniverse and modern C++/Python. Collaborative across autonomy, controls, and field teams, you will deliver robust, scalable simulation tooling.

Qualifications

• Bachelor's degree in Computer Science, Software Engineering, Robotics, ML, or related field.
• 3+ years of Python experience; C++ strongly preferred.
• 2+ years of software development in simulation, robotics, game engines, distributed systems, or autonomous systems.
• Experience building multi-threaded and multi-process networked systems with deterministic behavior and reliable message delivery.
• Experience running containerized workloads in cloud environments, including job orchestration, CI integration, and data I/O with Docker, AWS Batch, and S3.
• Capable of writing clear, concise documentation that accurately captures system design.

Responsibilities

• Cross-Functional Simulation Workflow Development: Work across autonomy, controls, and field engineering teams to develop and validate simulation workflows.
• Scalable Software Development: Write maintainable, scalable, and well-tested code in Python and C++ with clean, well-documented interfaces.
• Scenario-Based Simulation Tooling: Create tooling for scenario-based simulation workflows, including scenario authoring, test automation, and validation plans against real-world data.
• NVIDIA Omniverse Pipeline Development: Work in NVIDIA Omniverse, including USD workflows, Omniverse Kit/Code, PhysX, and Omniverse-based pipeline development.

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.

Career Area

Technology, Digital and Data

Help Build the Future of Caterpillar

At Caterpillar, technology always has a purpose, which is to solve our customers' toughest challenges. Through Cat Technology, we are solving problems by building the intelligence layer that connects machines, data, and people to make jobsites safer, more productive, and more sustainable. By combining deep domain expertise in physical systems with software, connectivity, autonomy, and AI, we deliver solutions that work in the real world - on real jobsites, at global scale.

Be Part of What's Next in Autonomous Construction Sites

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 Engineer builds the simulation engine behind Caterpillar's autonomous construction machines, developing the framework, simulation components orchestration and scalability enablement to support scenario-driven, high-fidelity machine, jobsite, and sensor simulations at scale in NVIDIA Omniverse to evaluate and improve autonomous systems.

The engineer will leverage NVIDIA Omniverse, modern C++/Python, and game engine principles to build the platform that will support the integration of robotic behaviors, autonomy systems, and sensor data into immersive visualization platforms.

Responsibilities
