Job Description

Parallel Domain is accelerating the development of autonomous systems through high-fidelity simulation and synthetic data generation. Our platform produces labeled sensor data--including camera, lidar, and radar streams--that helps teams train, test, and validate machine learning models at scale. With capabilities for both open- and closed-loop simulation, our tools provide configurable, realistic environments that unlock faster, safer iteration for AI systems.

We support a wide range of industries, including automotive, aerial robotics, agriculture, warehouse logistics, and security. Our customers--such as the Toyota Research Institute and Woven Planet--use Parallel Domain to improve perception systems and bridge the gap between simulation and the real world. Whether enabling virtual testing of autonomous vehicles or generating diverse edge-case scenarios for robotics, we help customers build smarter AI, faster.
