Information Services Tech Stack

National system integrator for Bulgarian public administration and government IT

Information Technology & Services Sofia 501–1,000 employees Founded 1970 Public Company

Information Services is Bulgaria's state system integrator, built on a heavy Microsoft and VMware foundation (Active Directory, Exchange, Entra, 365, Hyper-V) supplemented by AWS RDS and open-source Linux. The stack is mature and operations-focused rather than innovation-driven. Current hiring velocity is accelerating with engineering-heavy demand (7 of 13 open roles), concentrated at mid and junior levels, suggesting scaling of delivery capacity rather than architectural pivot—consistent with their active projects in CI/CD implementation and large-scale system builds.
