Water Treatment Equipment Maintenance Supervisor

This role manages maintenance of submerged membrane water-treatment equipment at facilities operated by government agencies and plant manufacturers. The equipment treats industrial wastewater from places such as beverage and food factories, as well as domestic wastewater. The work is split approximately evenly between desk work and maintenance activities.

Desk responsibilities include coordinating inspection dates between customers and partner companies, setting inspection items, planning work processes, preparing reports, managing equipment through a remote monitoring system, and attending regular internal meetings. On-site responsibilities include parts replacement, water-quality surveys, directing partner companies during inspection and specialist work, and meeting with customers. Maintenance is mainly scheduled periodic inspection work, and partner companies carry out much of the physical work under direction from this role.

The position works with customers, Kubota as the parent company, and external maintenance partners. The product is Kubota's submerged membrane unit, a membrane filtration system that separates activated sludge from treated water. The company manufactures and maintains these units as part of its water-infrastructure business.

Applicants must have graduated from high school or an equivalent level of education and hold an ordinary driver's license; an AT-limited license is accepted. Experience in construction management or other site-supervision work, field engineering, or employment with a plant manufacturer is welcomed but is not listed as mandatory. Training begins with learning the equipment and work procedures through practical experience. Employees with relevant experience are expected to take about one year to become able to handle the full range of work, while inexperienced employees may take two to three years. Customer accounts are gradually transferred after the employee can conduct inspections independently.

The position is based at the Tokyo office in Chuo Ward, Tokyo. It is a regular employee position with a three-month probationary period, during which pay and working conditions do not change. Working hours are 8:30 to 17:00, including a 45-minute break, for 7 hours and 45 minutes of scheduled work. Overtime is approximately 15 hours per month. Night or holiday work may occur a few times a year depending on the customer, with premium overtime pay provided for applicable hours. Sudden or nighttime call-outs are generally not expected.

Maintenance assignments may require day trips or overnight business trips and can last two days or more; the frequency varies by month. Remote work is available when office attendance is not necessary, including after a business trip or when site work finishes in half a day, subject to attending the office when instructed. Because this is a general-track position, transfers to another company location may occur.

Annual salary is JPY 4.5 million to 5.5 million. The posting also states a monthly base salary from JPY 275,000, determined according to experience and skills. The annual figures include approximately 15 hours of monthly overtime and two bonuses. Benefits include annual salary increases, bonuses, full transportation reimbursement, overtime and business-trip allowances, company housing, position and qualification allowances, an incentive payment, a cafeteria or meal subsidy, savings and employee-shareholding plans, a retirement allowance, uniforms, and support for U-turn and I-turn relocation. Social insurance is provided. Annual holidays total 125 days, including a five-day workweek with Saturdays and Sundays off in principle, public holidays according to the work calendar, paid leave, year-end and summer holidays, Golden Week leave, childcare, nursing-care, and condolence leave.
