Cornerstone Tech Stack

UK mobile infrastructure operator managing 5G rollout and network assets

Telecommunications Theale, England 201–500 employees Founded 2012 Privately Held

Cornerstone operates UK mobile infrastructure at scale, serving tens of millions of voice and data customers across network sites. The hiring mix tilts toward ops and engineering roles (9 of 19 open headcount) with manager-level seniority concentrated there, reflecting active operational scaling during 5G deployment. Stack is enterprise-standard (Power BI, Tableau, SQL, Azure, AWS, GCP) with notable gaps in DevOps/containerization tooling, suggesting infrastructure remains largely manually managed rather than fully automated.
