Sirma Tech Stack

Enterprise data platforms and AI solutions for regulated industries

IT Services and IT Consulting Sofia 501–1,000 employees Founded 1992 Public Company

Sirma is a 33-year-old Bulgarian IT services group (501–1,000 employees) built around data platforms, AI, and industry-specific software. The tech stack—Java, Spring, React, Kubernetes, PostgreSQL, Weaviate—points to a modernizing enterprise backend with semantic search and cloud-native infrastructure. Current hiring is engineering-focused (4 of 5 open roles) at senior and director levels, concentrated in Bulgaria, suggesting active platform development rather than geographic expansion. Acute pain points around data sovereignty, ISO 27001 compliance, and disaster recovery indicate the company is operationalizing AI and data products for regulated verticals (financial services, e-government).
