Hitachi Tech Stack

Infrastructure and industrial systems modernization via IT/OT integration

IT Services and IT Consulting Tokyo, Japan 10,001+ employees Public Company

Hitachi is a massive infrastructure and industrial conglomerate modernizing legacy systems at scale. The tech stack reveals a classic enterprise migration pattern: replacing mainframe and COBOL with cloud-native architectures (AWS, Azure, GCP) and containerization (Kubernetes, Istio), while actively adopting SAP S/4HANA, Infor, and Java. The hiring composition—dominated by senior engineers (461 of 496 in engineering) with concentrated focus on application migration, mainframe-to-cloud transitions, and core system refresh projects—signals a company restructuring its internal platform as both a competitive capability and a service offering to customers.
