Principal Backbone & Edge Architect

About Nscale

Nscale is the GPU cloud engineered for AI. We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers. Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.

At Nscale, our AI Infrastructure team plays a critical role in building the global network infrastructure that powers our GPU cloud platform, enabling reliable, high-performance connectivity across our data centres, customers, cloud partners, and global backbone.

We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you'll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you'll be contributing to building the technology that powers the future.

We are hiring a Principal Network Backbone & Edge Architect to serve as the senior technical design authority for Nscale's global network infrastructure.

You will design, validate, and own the technical standards governing our transport networks — from GPU data centre edge through WAN and backbone transport to cloud exchange connectivity and Internet peering.

This is a highly influential individual contributor role. While you won't have direct reports, your architectural decisions will define what gets built, how it gets built, and how Nscale's global network evolves.

You'll work across our global network organisation and engage directly with carriers, technology vendors, hyperscalers, and enterprise customers. We're looking for someone equally comfortable developing detailed architecture and design standards, evaluating emerging network technologies, and being hands‑on in a data centre validating a new backbone node.
