Search Engineer | Job Search Engine Operation

【 About the company 】

The company, which operates a purely domestic job search engine that began in 2015 as a new venture for a major job site operator, made a new start on November 12, 2019 as a joint venture company between Z Holdings Corporation ("Z Holdings") and Bizreach Inc.

The company aims to become the number one job search engine in the industry by combining the search technology of Z Holdings, which has been providing search services as a pioneer in the Internet industry, and the know-how of Bizreach, which has been disrupting industry conventions to create job search services for job seekers.

The business started in 2015 in order to solve the problem of the large number of job openings in the world, which are scattered across various job media and company websites, resulting in a large negative impact on job search.

In December 2020, the company integrated with "Yahoo! Job Search '' to further strengthen the collaboration with Z Holdings. From now, they are aiming to create products which create "new ways of working" that go beyond the framework of a job search engine by collaborating with various assets of Yahoo!
