CJ OliveNetworks Tech Stack
IT services and digital transformation for South Korea's largest conglomerates
CJ OliveNetworks is a 1,001–5,000-person IT services firm owned by the CJ conglomerate, built on 25+ years of systems integration and operational IT. The tech stack is backend-heavy (Oracle, Java, Spring Boot, Kafka, PostgreSQL) with emerging adoption of Kotlin and SAP S/4HANA, while still maintaining older stacks (Objective-C replacement signals modernization). The hiring mix is heavily senior-weighted (75% of open roles) and engineering-concentrated, but with decelerating velocity—suggesting mature internal systems and a shift toward advisory or managed-services delivery rather than large-scale project hiring.
