Cosmos Business Systems is a 36-year-old Greek IT services firm running a polyglot stack (Java/Spring, .NET/C#, PostgreSQL, Oracle, React/Angular) across infrastructure, telecom, and software delivery. The hiring mix—weighted toward senior engineers with one leadership role—suggests they're scaling delivery capacity rather than rebuilding. Active focus on public-sector digital transformation aligns with their core customer base (banking, telecoms, government agencies).
