Summary
At Caterpillar, technology has a purpose: to solve our customers' toughest challenges. Construction autonomy and Physical AI require trusted digital twins, high-fidelity simulation, scalable GPU computing, intelligent automation, and rigorous validation.
This Principal Engineer role is a hands-on technical leadership position responsible for architecture, critical implementation, engineering standards, cross-team alignment, and mentoring.
Role Purpose
Lead closed-loop simulation for robotics, autonomy, perception, planning, controls, and machine systems, bridging virtual environments with production robotics software and physical-machine testing.
What You Will Do
- Define the technical architecture for robotics and Physical AI simulation.
- Build closed-loop environments for autonomous and semi-autonomous machines.
- Lead Software-in-the-Loop, Hardware-in-the-Loop, and Vehicle-in-the-Loop strategies.
- Integrate ROS 2, autonomy software, machine controls, sensors, and simulation platforms.
- Develop camera, LiDAR, radar, GNSS, IMU, and machine-sensor simulation capabilities.
- Lead scenario generation, replay, regression testing, robot learning, and policy evaluation.
- Establish simulation-to-real correlation, fidelity, timing, determinism, and acceptance criteria.
- Scale parallel robotics simulation, reinforcement learning, and synthetic-data workloads on CoreWeave GPU infrastructure.
Principal-Level Leadership Expectations
- Own a major technical capability across multiple teams and programs.
- Translate ambiguous business and engineering problems into scalable architectures and production software.
- Lead architecture reviews, technical investigations, design decisions, and engineering standards.
- Balance research and prototyping with secure, maintainable, production-ready delivery.
- Mentor senior and developing engineers and support technical hiring and onboarding.
- Partner across simulation, robotics, autonomy, controls, AI, data, cloud, product, and customer-facing organizations.
Required Skills and Experience
- Advanced software engineering experience using Python and one or more of C++, C#, Java, Go, or Node.js.
- Experience with APIs, distributed systems, containers, automated testing, CI/CD, source control, and observability.
- Experience with cloud platforms and cloud-native architectures, including Docker and Kubernetes.
- Demonstrated ability to lead architecture and technical delivery across multiple teams.
- Strong communication, mentoring, problem-solving, and cross-functional collaboration skills.
- Experience using AI-assisted development tools such as GitHub Copilot, Claude, or Cursor.
- Deep hands-on experience with NVIDIA Isaac Sim and Isaac Lab for robotics simulation, learning, training, testing, and validation.
- Expertise with NVIDIA Newton or comparable GPU-accelerated physics engines, including rigid-body dynamics, contacts, friction, terrain interaction, vehicles, and robotic manipulation.
- Experience with NVIDIA Omniverse, OpenUSD, ROS 2, Python, and C++.
- Experience with NVIDIA Replicator for synthetic data and ground-truth generation.
- Experience with NVIDIA Cosmos or comparable world foundation models for Physical AI and sim-to-real workflows.
- Knowledge of perception, localization, planning, control, reinforcement learning, and autonomous-machine systems.
- Experience with SIL, HIL, VIL, real-time systems, coordinate frames, synchronization, and deterministic execution.
- Experience using CUDA, Docker, Kubernetes, NVIDIA Container Toolkit, and CoreWeave or comparable GPU cloud platforms.
Top Candidate / Preferred Experience
- Seven or more years of software development in robotics, autonomy, controls, or simulation.
- Experience with heavy equipment, off-road autonomy, autonomous vehicles, or industrial robotics.
- Experience building automated closed-loop regression environments and measurable sim-to-real correlation.
- Experience optimizing large-scale parallel simulation and robot-learning workloads.
