【Job Description】

■About the company
The company was established in February 2024 as a wholly owned subsidiary of Exawizards, Inc. and plans to develop a medical software product called a programmed medical device (SaMD) that fully utilizes AI and software technology, targeting not only the medical field but also the healthcare field. As the first of the new products, it has developed software for dementia diagnosis that can be used from smartphones, and plans to develop and offer several more products in the future.

■Background of Establishment of New Company
Exawizards has nurtured diverse business assets and seeds in the health and medical fields, including dementia, frailty, and locomotive syndrome, through the development of proprietary multimodal AI technologies, strategic acquisition of intellectual property, joint research and clinical research with academia for the development of programmed medical devices (SaMD), and joint planning and development projects with several major pharmaceutical companies.
As a mid- to long-term trend in the healthcare domain, there is now a serious increase in social security costs, diversification of health and medical needs, and widening regional disparities in medical services. Under such circumstances, there are high expectations for social implementation of digital technologies and services that utilize AI to fundamentally solve these social issues, not only in the medical field, but also across industry boundaries.
In order to respond to these social demands, the company plans to create a unique set of products and services and promote cross-industry social implementation. At the same time, the company will further strengthen compliance with related laws and regulations, quality control, data management, and other aspects of its business related to health and medical themes in order to solve the social issues it aims to address.

■Attractiveness of this position
By utilizing AI technology, you will be able to experience SaMD (medical SW) development from the ground zero phase, one of the fields that is currently attracting the most attention in Japan and abroad for dementia.
By developing services that lead to solutions not only for dementia, but also for various other diseases and social issues, you will gain a wide range of experience in the medical and health field, not limited to a single disease or medical field.
It is an environment where you can improve your skills by working with engineers with diverse skills, such as AI engineers and SW engineers.
