[EC Platform] PHPエンジニア
職種Position System Engineers / Infrastructure Engineers / Web Engineers / Game Developers
会社概要Company profile This is a company that supports the liquidation of corporate inventory based on large volumes of actual transaction data from Amazon, ヤフオク!, and others.
The group operates a variety of services, including an AI-based service that proposes the "market value" of products for retailers and manufacturers struggling with inventory, a market price information service for individuals who purchase and sell such inventory as a "side business," and the provision of operational efficiency tools.
They continue to expand their business with a BtoB wholesale platform, a tool for streamlining integrated EC operations, a socially conscious EC site, and more.
The company's strength lies in its network for distributing products around the world, and its ability to bring together and integrate over 700億件 of EC and physical store product transaction data with over 100万アカウント of small B (small-scale sole proprietors / side business workers). AI analyzes "where and at what price a product will sell," and small B sells it off, reducing the risk of products being discarded as excess inventory. The cumulative number of customer business-use accounts has surpassed 100万件 and continues to increase every month; as the shift to EC accelerates, demand is likely to grow even further.
