Senior / Lead SaaS Product Manager

This product management role is responsible for Pro One, an operational improvement SaaS for field-service businesses. The role focuses on understanding customer problems, proposing and expanding possible solutions, deciding product direction, preparing PRDs, managing development progress, tracking post-release KPIs, and improving the product development and improvement process while establishing best practices. The scope of duties may change to other work defined by the company.

Pro One is a vertical SaaS product for the short-term construction market, created from discussions with service providers using Mitsumore. It is designed to manage work across sales, construction management, and back-office operations in one system. Functions include report and estimate creation, customer management, and schedule management. The product is intended for use by companies ranging from large enterprises to small and medium-sized businesses and by both management and field staff.

The product supports customer-side customization within the SaaS, reducing the need for company-specific custom development and allowing organizations with limited initial budgets to start using it quickly. The posting states that research with field operators and a US company providing a similar service informed the product design, including a user interface that reduces administrative work such as handling invoices in different formats. The stated result is a 30% reduction in administrative work.

Required experience is at least two years of product management. Preferred experience includes coordinating smoothly with internal and external stakeholders and handling a broad range of product-owner responsibilities, such as strategy planning and management. English-speaking ability is listed as a preferred skill, with TOEIC 800 or above given as a guideline because some engineers speak English. The role also calls for independently identifying customer problems and opportunities, understanding customer operations deeply, presenting solutions, exchanging opinions, communicating smoothly with team members, and moving projects forward.

The position offers experience building a business-to-business vertical SaaS product, launching a new business, solving complex industry-specific problems, and developing products in a global environment. It is a permanent full-time position in Ginza, Chuo-ku, Tokyo. The office is approximately five minutes from Higashi-Ginza Station, six minutes from Ginza Station, nine minutes from Shimbashi Station, three minutes from Tsukijishijo Station, and eight minutes from Shiodome Station.
