Job Description:

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.

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.

The Role

To own the demand generation campaign strategy and performance marketing execution for the Cornerstone, designing and delivering integrated, high-impact campaigns that drive measurable pipeline contribution across both core and new business acceleration priorities.

This role blends marketing craft and commercial performance: developing campaign thinking, audience targeting, messaging strategy and creative performance frameworks, then executing, optimising and improving results through insight-led iteration.

Why This Role Matters

This is a high-impact role at a pivotal point in Cornerstone’s growth. As the business expands its propositions and sharpens its commercial focus, this role will play a key part in turning strategy into demand — building campaigns that not only raise awareness, but also generate quality engagement, stronger leads and measurable pipeline contribution. It’s an opportunity to shape how Cornerstone shows up in the market, bring more consistency and creativity to performance marketing, and help create a smarter, more connected campaign engine that supports both immediate priorities and long-term growth.

What You’ll Do

Own demand generation strategy across core propositions, launches and growth programmes, translating commercial priorities into integrated campaigns that drive pipeline impact.
