EC Business Growth Lead Manager

Belong is hiring a lead manager to drive the major EC marketplaces for its refurbished smartphone sales business, with Amazon as the main platform and Rakuten and Yahoo also included. The role covers strategy development and execution aimed at maximizing sales and profit.

Day-to-day responsibilities include analyzing market, competitor and company data; determining prices that generate profit; controlling inventory; and identifying issues through quantitative analysis of sales, profit margins and inventory turnover. The role also includes planning campaigns, measuring their results, and increasing customer acquisition and sales in coordination with existing EC and business development members.

EC marketplace operation experience is not required. The posting seeks someone who has carried responsibility for sales or profit in an operating company and has repeatedly used data to drive practical, fast-moving PDCA cycles. Marketplace-specific operational knowledge and customer support processes can be learned after joining from internal business development and EC operations professionals.

The role supports the B2C refurbished smartphone business “Nicosuma,” which sells, purchases and rents reused smartphones. The successful candidate will learn the product flow, including how devices are sourced and sold, then may progress from operating within marketplace rules to changing those rules through improved sourcing methods or new sales schemes. A future career path may include leading expansion at overseas locations such as the United States.

The work location is the Tokyo head office in Akasaka, Minato-ku. The company states that the location may change to a company-designated place, including a place used for remote work. An office move to the area around Aoyama-itchome Station is planned for autumn 2026, with work continuing at the current location until the move. The selection process consists of document screening, two to three interviews, a reference check and an offer meeting.
