eir operates Ireland's most extensive telecommunications network, serving approximately 2 million customers across residential, SMB, enterprise, and government segments. The company is actively modernizing its internal tooling—adopting GitHub Copilot while migrating away from Dynamics 365—and hiring heavily in sales (40 roles, mostly junior) alongside a smaller engineering footprint, suggesting a shift toward AI-assisted go-to-market functions and automation templates rather than platform development.
