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.

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.

Our connected ecosystem brings together massive volumes of high-quality data to create a foundation where engineers like you can build and deploy against.

If this work motivates you, we invite you to join our team. In these roles, you’ll work at the intersection of the physical and digital worlds. You’ll help design and deliver intelligent systems that enable machines to perceive their environment, make informed decisions, and support safer, more productive operations.

What You Will Do:

• Developing detailed architecture deliverables to solve business problems.

• Designing an application's technical infrastructure, such as specific databases, programming languages, utilities, and testing approaches

• Leading the evaluation and deployment of new technologies to add or enhance existing digital technical capabilities.

• Participating in addressing business requirements for applications and collaborating with cross-functional teams to deliver digital solutions that meets business results.

What You Will Have:

• Requirements Analysis: Knowledge of tools, methods, and techniques of requirement analysis; ability to elicit, analyze and record required business functionality and non-functionality requirements to ensure the success of a system or software development project.

• Analytical Thinking: Knowledge of techniques and tools that promote effective analysis; ability to determine the root cause of organizational problems and create alternative solutions that resolve these problems.
  • Platform Architecture: Knowledge of technologies and methods to design processing mechanisms and roadmaps to execute business application systems; ability to design these roadmaps and deploy supportive interfaces for end-users to access related systems, in accordance with standards and processes.
  • Target Architecture: Knowledge of target architecture; ability to develop the IT blueprint and roadmap while aligning the architecture and processes with business strategies and objectives.
  • 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.

  Top Candidates Will Have:

  • Simulation Engine Architecture – Typically 8+ years in software engineering with ownership of a production simulation platform for autonomous vehicles or robotics: core abstractions, deterministic execution, replay and closed-loop modes, SIL/HIL integration.
  • Omniverse and Game Engines – Hands-on NVIDIA Omniverse / Isaac Sim (Kit, OpenUSD, PhysX, RTX) and/or Unreal Engine as a simulation foundation; Applied Intuition, CARLA, Isaac Lab, MuJoCo, or Project Chrono a plus.
  • High-Fidelity Physics – Multibody dynamics, contact and friction, deformable terrain and granular material, track/tire-ground interaction, hydraulics and powertrain; models calibrated and validated against test data.
  • Sensor Simulation – Physically based camera, LiDAR, radar, GNSS, and IMU models including dust, weather, noise, and calibration effects, validated against real sensor logs; exposure to 3D Gaussian Splatting / NeRF.
  • World and Scenario Simulation – Large outdoor terrain and geospatial environments; procedural and generative scenario generation with coverage tied to the ODD; familiarity with ASAM OpenSCENARIO and SOTIF / ISO 26262.
  • Reinforcement Learning and Neural Simulation – Gym-style RL environments and large-scale closed-loop training (Isaac Lab, Ray); understanding of world foundation models (NVIDIA Cosmos) alongside physics simulation.
  • Scale and Performance – Simulation on GPU clusters and cloud (Kubernetes, Slurm, Ray, CUDA) with a record of improving throughput, determinism, and cost per simulation.
  • Software Engineering – Expert modern C++ and strong Python; gRPC / Protocol Buffers, Bazel or CMake, CI/CD for large monorepos; Rust or CUDA a plus.
