Principal Cloud Network Architect in Cardiff

i Quila is a rapidly growing technology company specialising in advanced networking, telecommunications, automation and AI-driven network intelligence solutions.

As we continue to expand our global footprint and deliver large-scale solutions with leading telecommunications providers and enterprise customers, we are seeking an exceptional Principal Cloud Network Architect to lead the design and delivery of our next-generation cloud networking platform.

This is a rare opportunity to shape a carrier-grade architecture that integrates cloud, telecommunications and AI technologies at scale.

This is a senior, high-impact role for someone who wants to influence platform architecture, work directly with major telecommunications partners and help build carrier-grade cloud networking services at international scale.

You will be responsible for designing, implementing and operating a highly scalable networking platform hosted within Microsoft Azure that integrates with major telecommunications providers and other carrier partners.

The role combines deep cloud networking expertise with service provider technologies.

You should be equally comfortable discussing BGP with a carrier architect, designing Azure landing zones, deploying EVPN/VXLAN infrastructures, leading technical governance and guiding complex customer-facing projects.

You will act as the senior technical authority for network architecture, cloud connectivity, automation and operational governance.

You will help define the strategic direction of the i Quila platform, support customer engagements with major telecommunications providers and enterprise organisations, and provide architectural leadership across engineering, operations and commercial discussions.
