Brand Marketing Manager

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.

Build the brand that drives our next phase of growth

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.

This is a new role

As we accelerate into new products, new markets, and new opportunities, brand will play a defining role in what our success will be. This is a new role, it isn’t about stewardship. It’s about building a brand that actively drives growth.

The Role

You’ll lead brand marketing at Cornerstone, building awareness, trust, and preference with the audiences that matter most, and creating the conditions for demand to grow.

You’ll define how we show up, what we stand for, and how we bring that to life; consistently, creatively, and with impact.

Why This Role Matters

We’re not just growing, we’re evolving.

This role will shape how we’re understood in the market, how we differentiate, and how we win in new spaces.

It’s a chance to build a brand with real commercial impact, and see the results of your work quickly.

What You’ll Do

• Own the brand marketing strategy and roadmap aligned to strategic priorities, core growth, and new products/verticals.
• Create high-impact campaigns that cut through at the top and middle of the funnel.
• Turn strategy into clear positioning, sharp messaging and compelling creative themes.
• Keep the brand “always on” with thought leadership, market education, and trust-building campaigns.
• Build integrated campaigns across launches, category education, and “always‑on” brand.
• Partner with Product, Sales, Content and Performance to turn attention into pipeline.
• Ensure a strong, consistent brand across all channels and key touchpoints.
• Constantly test and refine – measure and optimise tracking awareness, engagement, and market impact.

What You’ll Bring

You’re a B2B brand marketer who knows how to make complex propositions land and drive results.

You can shape smart, multi‑channel campaigns for complex propositions, craft clear positioning and messaging people actually remember, and write briefs creatives love. Most importantly, you get how brand sets the stage for demand generation to do its best work.

You know B2B brand and upper‑funnel marketing inside out, especially launches, new markets, and messaging that sticks. You’re a natural storyteller who can brief brilliantly, bring stakeholders with you, and ship great work without dropping the details. You’ve led brand campaigns before, worked with studios/agencies, and partner smoothly with performance and content teams to turn attention into action.
