Careers

Most of what we make is never seen, and the people who make it are used to that. They are engineers who like to know that a controller they designed will still be running when they retire, technicians who can repair a board made before they were born, and field engineers who are called when equipment must not stop.

Hosaka recruits new graduates in Japan every April and experienced people throughout the year in every Group company. Recruitment of new graduates is conducted in Japanese; please see our Japanese website.
