Meet the Team
Join our dedicated Customer Network Support (CNS) team supporting mission-critical enterprise and public sector customers with strict UK Data Sovereignty mandates. We serve as the vital bridge connecting sovereign customer environments with Cisco’s global technical ecosystem and worldwide TAC. Operating at the forefront of network engineering, high-stakes incident management, data governance, and AI-driven support operations, our team ensures customer networks run securely, reliably, and with full regulatory compliance.
Your Impact
As a Senior Network Support Engineer, you will act as the primary interface for customers with UK Data Sovereignty concerns into global Cisco support services. In this high-impact role, you will analyse and de-sensitise critical customer network data to safely route complex issues to the appropriate global Cisco Support and TAC teams, and serve as the conduit conveying remediation plans back to the customer for full resolution.
AI adoption and enablement are central to the delivery of this role. You will leverage AI-assisted tools, intelligent data sanitisation utilities, and modern analytics to accelerate incident triage, automate log de-sensitisation, enhance root-cause analysis, and drive operational efficiency. As a senior member of the team, you will also provide vital support and mentoring to fellow engineers—enforcing consistency, quality, and Continual Service Improvement (CSI) across all team service deliverables.
At Cisco, we’re revolutionizing how data and infrastructure connect and protect organizations in the AI era – and beyond. We’ve been innovating fearlessly for 40 years to create solutions that power how humans and technology work together across the physical and digital worlds. These solutions provide customers with unparalleled security, visibility, and insights across the entire digital footprint.
Fueled by the depth and breadth of our technology, we experiment and create meaningful solutions. Add to that our worldwide network of doers and experts, and you’ll see that the opportunities to grow and build are limitless. We work as a team, collaborating with empathy to make really big things happen on a global scale. Because our solutions are everywhere, our impact is everywhere.
We are Cisco, and our power starts with you.
