TIER IV Tech Stack

Open-source autonomous driving platform and commercialization services

Motor Vehicle Manufacturing Tokyo, Shinagawa-ku 201–500 employees Founded 2015 Privately Held

TIER IV develops Autoware, an open-source autonomous driving software stack, and provides turn-key commercialization services for autonomous vehicle deployments. The tech stack reveals a mature systems-level operation: C++, ROS 2, PyTorch, and safety-critical standards (ISO 26262, AUTOSAR) dominate, paired with cloud infrastructure (AWS, GCP, Azure) and emerging CI/CD adoption—indicating a transition toward faster release cycles. The engineering-heavy org (39 engineers vs. 4 data, 2 sales) with active projects spanning algorithm development, MLOps, and Linux kernel work confirms TIER IV is building infrastructure, not a closed platform.
