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.
We are looking for system engineers who are excited about helping build the best in class "software first" automotive platform. We envision the Arene platform will change the way vehicles are made. Ideally you would be familiar with the challenges associated with the automotive software lifecycle and are motivated to solve them.
We offer a stimulating and cooperative team environment, where adaptability that doesn't compromise safety is our main priority. Our communication language is English, but we are primarily located in the exciting international metropolis of Tokyo. Our values harmonize the best of "Silicon Valley Innovation" and Toyota Craftsmanship. Relocation support is available.
We learn from each other, as well as support and encourage ongoing training such as:
・New languages: Interested in learning English or Japanese? How about a multitude of software and system development languages like modern C++ and SysML? Our ongoing training program will allow you to build the skills that align with your interests and job function.
・Automotive development: Want to learn about Toyota's Production System and similar methodologies? We will help you build expertise in these areas and put your newly acquired skills to work immediately.
・Software safety and security: We are committed to giving you the training opportunities you need to help us develop automotive software that is safe and secure.
We put a strong emphasis on ethics and team values, which include:
・Be Reasonable
・Work with Integrity
We believe in:
・Creative Ownership
・Grow together through teamwork
・Courage to make history
Ask us what these values mean to us.
