Senior Portfolio Asset Manager in Theale

Vision: To be the UK’s leading digital infrastructure partner, enabling a fully connected future. Deliver reliable, high quality site access, infrastructure and services that support our customers’ evolving connectivity needs.

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.

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. 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.

• Own the end-to-end programme: renewals, acquisitions, upgrades and transactions—protecting tenure and continuity.
• Drive performance: delivery, governance, forecasting, and Capex/Opex targets—with clear visibility of progress.
• Partner closely with Property, Estates, Legal, Finance and Operations to get deals done smoothly.
• Improve how we work: process tweaks, governance upgrades, and supplier performance management.
• Manage risk and compliance (company standards, H&S, environment, BC and info security) to avoid surprises and extra costs.

Considerable telecoms property functional knowledge gained from working in a mobile network environment. Experience of telecoms asset management and/or site portfolio management is preferred. Knowledge of property litigation including an understanding of the Electronic Communications Code and Landlord & Tenant Act legislation in the UK. Excellent ability to communicate successfully with people at all levels both inside and outside Cornerstone, both verbally and in writing. Strong planning & organizational ability in delivering business results.
