MUSINSA is a Korean fashion marketplace operator founded in 2001, now operating community, magazine, storefront, creator spaces, and resale channels. The tech stack spans consumer (React, TypeScript) and backend infrastructure (Java, Spring, PostgreSQL, MongoDB, AWS/GCP/Azure), with active adoption of GitOps tooling (ArgoCD, Karpenter, KEDA) and AI coding assistants (Claude, Copilot, OpenAI). Engineering-led hiring (48 roles) focused on senior IC positions signals infrastructure-heavy scaling—active projects center on real-time recommendation APIs, multi-platform core integration (OCMP), and MSA migration, while pain points cluster around traffic handling and large-scale data pipeline management.
