Senior Software Engineer, City OS - IoT

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.

Toyota’s 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 a diversity of cutting-edge technologies. It will be the world’s most programmable city. At the same time, it is also ‘human-centric’, serving the needs of its citizens and keeping people safe, comfortable, and happy.

Our mission is to create the digital heart of Woven City: a software platform called “CityOS”. All digitally connected services in the city will be orchestrated and delivered on this platform. The technical challenge is huge and includes creating state-of-the-art systems for collaborating microservices, identity, authentication, privacy, security, data broking, IoT control, and much more. The platform will be open to third-party inventors who will collaborate with us to unlock the potential of the world’s smartest city.

In particular, the IoT team is responsible for building services and flows to manage IoT devices through their entire lifecycle. We empower inventors to deliver on their mission with modern technologies exploring new paradigms.
