Full-Stack Prototype Engineer, Mobility Vision, Woven Products

Woven City – Mobility Products / Employee / Hybrid

Woven by Toyota is enabling Toyota's once-in-a-century transformation into a mobility company. Inspired by a legacy of innovating for the benefit of others, our mission is to challenge the current state of mobility through human-centric innovation — expanding what "mobility" means and how it serves society. Our work centers on four pillars: AD/ADAS, our autonomous driving and advanced driver assist technologies; Arene, our software development platform for software-defined vehicles; Woven City, a test course for mobility; and Cloud & AI, the digital infrastructure powering our collaborative foundation. Business-critical functions empower these teams to execute, and together, we're working toward one bold goal: a world with zero accidents and enhanced well-being for all.

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. Our mission is to identify the customer needs through careful validation and create new products and services to help transform Toyota into a Mobility Company. In a dynamic and uncertain environment, members are expected to take initiative, adapt proactively, and drive their work autonomously to deliver impact. If you're detail-oriented, but thrive in an environment where you need to be scrappy, this team might be right for you. While our team is diverse in nationality, language, and gender, we also value and respect the culture of Toyota. We follow a hybrid workstyle, combining office and remote work. Additionally, depending on future circumstances, day trips or work assignments in Woven City (Susono, Shizuoka Prefecture) may be required.

Responsibilities

• Rapidly prototype and iterate on mobile applications (iOS/Android) using Flutter or native frameworks to validate product ideas with real users in fast-paced cycles.
• Design and implement scalable cloud backends using Node.js, Python, or Go, integrating necessary services like geolocation, map APIs, and storage for functional end-to-end prototypes.
• Integrate AI models and APIs developed by collaborating teams into backend systems to deliver intelligent user-facing features.
• Develop and maintain REST/GraphQL APIs to enable seamless communication between frontend and backend components across platforms.
• Collaborate cross-functionally with UX researchers, designers, and product managers to translate conceptual ideas into working systems and ensure technical feasibility early in the development process.
• Deploy prototypes with basic CI/CD and observability setups, ensuring systems are testable, maintainable, and extensible toward production-ready implementations.

Minimum Qualifications

• 5+ years of experience in software engineering, with a focus on mobile and backend development in early-stage product environments
• Proven ability to rapidly prototype and iterate on mid- to high-fidelity solutions using technologies such as image-based AI, geolocation/map services, and cloud platforms (e.g., AWS, GCP)
• Experience in end-to-end system development, including REST/GraphQL API design and integration of AI APIs (e.g., LLMs, ML inference servers)
• Strong collaboration skills, with a track record of working effectively with product managers, UX researchers, and cross-functional teams
• Excellent problem-solving skills and the ability to propose scalable and practical technical approaches in ambiguous and fast-paced environments
• Business-level English and Japanese communication skills
