Vision: Cornerstone’s leading digital infrastructure partner
About the Role
Korps an industry-leading digital infrastructure company, we enable a fully connected future. Our mission? Deliver reliable, high-quality site access, infrastructure, and services to meet the UK’s evolving connectivity needs.
For almost two decades, our work has supported the nation’s mobile networks. Now, our future is accelerating — creating more connectivity faster, for more communities and industries.
This is a high-visibility, cross-functional role focused on HSQE (Health, Safety, Quality, Environment) Supplier Governance. You’ll:
