Job Description ■Business Overview
In this position, you will be assigned to the CareWiz business, which offers services for the caregiving sector.
CareWiz operates under the mission: “Leveraging AI and systems to realize a diverse super-aged society.” By providing technology-driven services, CareWiz enables caregivers to focus more on people and less on administrative burdens.

One of the core products, CareWiz Toruto, is an AI-powered physical function analysis service developed using AI technology and the expertise of physical therapists. It allows users to easily visualize physical functions—such as gait and oral movement—simply by recording a video with a smartphone.
The results are displayed in an easy-to-understand communication sheet, which can be shared directly with users, their families, and care managers. Additionally, it promotes smoother collaboration among staff by enabling communication through video-based assessments.
The service has already been introduced in over 700 care facilities and municipalities across Japan, supporting simpler and more evidence-based gait analysis and on-site assessments.

Currently, CareWiz Toruto has been implemented in approximately 800 care facilities across Japan, achieving an 80% reduction in the time required for physical function assessments (*1).
Additionally, 95% of users who experienced gait analysis expressed a desire for regular assessments (*2).
The number of individuals analyzed has now surpassed 100,000, demonstrating the widespread adoption and impact of the service.

■Role Overview
You will be responsible for both Tech Lead duties and product design in the development of CareWiz Toruto.
Across multiple projects related to Toruto, the Tech Lead is expected to ensure system and code quality as well as architectural design, while also collaborating with the PO/PM to lead product design.
