GEK TERNA Group of Companies Tech Stack

Infrastructure and energy group executing major Greek development projects

Construction Athens, Attiki 5,001–10,000 employees Founded 1969 Privately Held

GEK TERNA is a diversified construction and infrastructure group managing ~8,000 employees across Greece and international markets. The tech stack reveals a heavy SAP footprint (ERP, S/4HANA migration underway, FI/SD/MM modules) paired with specialized project-delivery tools (Oracle Primavera, Revit, AutoCAD, VISSIM traffic simulation)—a pattern typical of large-scale infrastructure operators juggling procurement, financials, and site coordination. Active hiring is engineering-concentrated, with leadership gaps in MEP (mechanical, electrical, plumbing) technical oversight, signaling scaling pressure on delivery-critical functions.
