Woven by Toyota is building mobility for a safer, happier and more sustainable world. A subsidiary of Toyota, Woven by Toyota develops and invests in new technologies, software, and business models that transform how we live, work and move. With a focus on software-defined vehicles, automated driving, data-driven intelligence, security, mobility services, embedded platforms, AI, and more, we build on Toyota's legacy of trust and safety to deliver mobility solutions for all.
For nearly a century, Toyota has been delivering products and services that improve lives. Its earliest offerings, which automated the simple manual task of weaving, have evolved into the safe, reliable, connected automobiles we enjoy and depend on today. Woven by Toyota is an integral part of Toyota’s vision for the next 100 years—a world where mobility is easier, safer and more enjoyable for more people.
Our unique global culture weaves modern Silicon Valley innovation and time-tested Japanese quality craftsmanship and operational excellence. These complementary strengths enable us to develop and deliver cutting-edge technology at scale—optimizing for safety, advancing clean energy and elevating well-being. We envision a human-centered future where world-class technology solutions expand global access to mobility, amplify the capabilities of drivers, and empower humanity to thrive.
The Toyota Woven City is a fully-connected ecosystem powered by hydrogen fuel cells to be built at the base of Mt. Fuji in Japan. It is envisioned as a “living laboratory” and “ever evolving,” incorporating various types of cutting-edge technologies. At the same time, it is also “human-centric;” that is, it is expected to keep people safe and comfortable.
Woven City’s R&D team will develop innovative products and services using technologies developed by Toyota Motor Corporation.
Our mission is to:
1. Develop services and products for Woven City
2. Expand capabilities through long-term R&D
Toyota Motor Corporation has been involved in a variety of technological development in the robotics, energy, and automotive domains for a long time. Our team will leverage Toyota’s hardware expertise in these fields to create new value by developing software on top of this.
Our team will develop innovative services that are essential to the city. As a first-party developer, we will also build a foundation upon which third-party partners can participate. Therefore, we are responsible for not just the applications but also the core software and capabilities.
Our team consists of many highly experienced members with international work experience. We strive to be open-minded as we create a new culture with members from various backgrounds and nationalities. Our global team works closely with the Toyota Motor Corporation and the Toyota Research Institute in North America to develop our technologies and products.
We are seeking talented people to join us as we take on new challenges to create new products and services for the Toyota Woven City.

We’re looking for an engineer who is excited about making a simulator for various “smart city” activities and which enables testing of mobility, logistics, and other services without a physical environment. With hands-on experience and deep knowledge about network communications, you are expected to design and develop the network interfaces between numerous components in the digital-twin software system. This “digital-twin” simulator will initially be used as a testing platform for Woven City before its construction is complete, and will remain as a virtual mirror of the city to allow 1st and 3rd parties to test within the city environment before actually deploying their hardware.


  • Design, implement, and maintain network architecture for a large-scale software simulator
  • Work with other component teams to define interface requirements and test network connections
  • Optimize network performance and identify bottlenecks
  • Troubleshoot network issues and devise solutions
  • Work with other engineers to improve overall system performance
  • Document network architecture and procedures


  • Bachelor's degree in Computer Science or related fields
