Technology, Information and Internet 千葉市稲毛区, 千葉県 1,001–5,000 employees Founded 1998 Public Company

ZOZO operates a multi-service fashion business spanning e-commerce (ZOZOTOWN), a social coordination app (WEAR), and proprietary measurement systems (ZOZOSUIT, ZOZOMAT, ZOZOGLASS). The tech stack reveals a mature, polyglot infrastructure: BigQuery + Google Analytics for analytics, Kubernetes + ECS for orchestration, and PostgreSQL + DynamoDB for persistence. The hiring profile is heavily weighted toward mid-level engineering and legal/ops support, while active projects signal an internal shift—web application replacement and measurement-system consolidation dominate the roadmap, suggesting infrastructure modernization is a near-term focus.
