Vision: To be the UK’s leading digital infrastructure partner, enabling a fully connected future
Mission: Deliver reliable, high quality site access, infrastructure and services that support our customers’ evolving connectivity needs.
About us
For almost two decades, Cornerstone’s infrastructure has quietly supported the UK’s mobile networks. Whilst we continue to strengthen that foundation and extend its reach, we’re in an exciting period of acceleration and product development that will see us enable more connectivity and compute to more communities and industries across the UK.
You’ll be the go-to person for big, complex estate partners—think Network Rail, TfL, utilities, councils and airports building long-term relationships and landing the deals that keep our sites live (and growing).
You’ll negotiate acquisitions and renewals, steer estate management, and be the calm escalation point when commercial or property issues heat up. You’ll also spot new ways to unlock value across portfolios (site-sharing, smart collaborations, better use of real estate) and drive projects from idea to delivery—on time, on budget and to a high standard.
Why This Role Matters
Our network only works if we have the right sites, in the right places, on the right terms and that’s exactly what this role protects and unlocks. You’ll keep critical portfolios secure and service-ready, turning complex property negotiations into continuity for our customers and confidence for our shareholders. Just as importantly, you’ll spot smarter ways to use real estate, improve how we deliver, and help the business grow faster, safer and more efficiently.
