Toyota is redefining what it means to move. We're challenging the current state of mobility by enhancing the movement of people, goods, information and energy. Centered around three core concepts - A Living Laboratory™, Human-Centered, and Ever Evolving City™ - Woven City serves as a test course for mobility to fulfill our purpose of well-being for all.
We do this by bringing together a diverse community of people with a shared passion for the future of mobility to co-create, develop and refine innovative products and services. This cross-section of social infrastructure, mobility, and people provides a unique opportunity for inventors, residents and visitors to interact seamlessly with new technologies throughout daily life in an environment that emulates a real city.
People Empowerment AI is part of Woven City Management. We develop AI products that draw on people's experiences and knowledge to support learning, decision-making, and invention. Our goal is to deliver useful services for people working in Woven City, Inventors, Weavers (residents), and the wider Toyota Group.
Our team offers the opportunity to develop products in the setting of a real city, working closely with users and experts from different disciplines. In a small team, you will contribute from problem discovery through development and validation, refining products while seeing how they create value for people.
