Software Engineer, Backend | Part-time job search app

【 About the company 】

The company's mission is to "create an infrastructure that expands life's possibilities through 'work'" and is developing businesses such as "Timee," a part-time job application for people with limited free time.

In recent years, the declining birthrate and aging population have led to a serious shortage of people to engage in labor, and at the same time, the burden on workers has been increasing.
The company's "Timee" can solve management issues related to "people" that companies are facing, such as resolving labor shortages and improving the workplace environment.

Also, the company aims to fundamentally change the way people work, to solve the problems faced by the traditional part-time and temporary employment industry, and to create a world in which each individual can work when they want and spend more time on their own.

Five years after its release, the service has surpassed the following
・Number of users: 5 million
・Number of stores: 130,000
・Number of companies using the service: 46,000 companies

The company plans to continue its efforts to create an infrastructure that enriches the time of each and every individual through a variety of approaches that go beyond "work".
