About the Role
Own a Carrier-Grade Network | Lead Infrastructure Operations | Clear Progression to CTO
We're working with a technically advanced telecoms and communications business that operates its own carrier-grade infrastructure, delivering business-critical unified communications and telephony services across a resilient multi-site environment. As the organization continues to grow, they're looking to appoint an experienced Infrastructure Manager to take ownership of their entire network estate while leading the day-to-day operations of a skilled infrastructure team.
This is a rare opportunity for a senior networking professional who wants to combine hands-on technical ownership with people leadership and operational responsibility. You'll be the senior owner of a complex on-prem infrastructure estate spanning multiple interconnected sites, taking responsibility for everything from BGP operations, peering, RIPE resources, routing policy, and network resilience through to incident management, governance, documentation standards, and team development.
Rather than stepping into a purely managerial position, this role offers the chance to remain deeply involved in the technology while shaping the wider infrastructure function. You'll work closely with senior technical stakeholders, support carrier-grade network operations, drive operational improvements, and play a key role in network architecture, service continuity, disaster recovery planning, and major customer network projects. It's an excellent opportunity for someone who enjoys ownership, leadership, and solving complex networking challenges in a live production telecoms environment.
