What we need:
Reporting to the Director of Digital Infrastructure Operations, the Principal Network Architect owns the end-to-end network architecture across Digital Edge’s WAN, backbone, data centre, interconnection and hybrid cloud environments. The role combines deep network expertise with a practical understanding of compute, operating systems, virtualisation, storage and application dependencies to deliver high-performance, resilient services.
The architect will translate business and workload requirements into integrated designs, evaluate trade-offs across infrastructure domains, and lead delivery with systems, platform, security and application teams. Success is measured by end-to-end service performance, availability, recoverability, operational efficiency and lifecycle cost.
Key responsibilities:
1. Holistic Infrastructure Architecture
- Own integrated architecture, reference designs, and roadmaps connecting physical and optical infrastructure, IP networks, compute, storage, and platforms.
- Map application flows and service dependencies; define capacity, latency, availability, security, recovery, and lifecycle cost requirements.
- Document design trade-offs, migration plans, acceptance criteria and operational ownership for each architecture decision.
- Establish and govern network architecture standards, design principles and an architecture review process, ensuring new builds and expansions across the regional portfolio conform to approved designs.
- Develop CapEx and OpEx business cases, total cost of ownership models and multi-year network budgets to support new data centre builds and capacity expansion.
2. Systems and Platform Design Considerations
- Apply a working understanding of Linux, server hardware, CPU and memory resources, virtualisation, and containers to network design decisions; hands-on engineering of these platforms remains with the systems and platform teams.
- Assess how host networking, TCP/IP behaviour, NICs, MTU, virtual switches, load balancers, DNS, and time synchronisation affect service delivery.
- Account for storage access, I/O performance, replication, clustering, and backup traffic when designing bandwidth, latency, and recovery requirements.
- Engage systems and application specialists during design to understand host, storage, and service dependencies, and review workload test results to confirm network designs meet performance requirements.
3. Network Service Architecture and Technology Selection
- Architect WAN, backbone, data centre, internet and cloud connectivity as an integrated end-to-end design across sites, carriers and markets, supporting both IPv4 and IPv6.
- Select the appropriate routing, switching, overlay and transport technologies for each service type, such as internal infrastructure, customer interconnection, data centre interconnect and cloud connectivity, based on scale, resilience, latency, security, operational complexity and cost.
- Define routing and traffic-control architecture principles, including domain hierarchy, policy, segmentation, traffic engineering and convergence, proving each principle with working reference configurations before engineering teams complete detailed design and rollout.
- Maintain a technology selection framework and service design patterns that map service requirements to approved technologies, reviewing them as technologies and business needs evolve.
- Architect customer interconnection services, including cross-connects, internet exchange, IP transit and cloud on-ramps, and support sales and solutions teams with customer-facing technical design and pre-sales engagement.
4. Physical Infrastructure and Optical Transport
- Define cabling and physical infrastructure standards, including patching, labelling, route diversity and acceptance testing, ensuring the physical design supports the resilience and capacity needs of each service.
- Select the appropriate optical transport approach for each service type, such as dark fibre, DWDM or managed wavelength services, based on capacity, reach, latency, protection and cost.
- Validate optical and physical designs through link budget validation, transceiver interoperability and acceptance testing before handover to engineering for build and rollout.
5. Service Performance and Resilience
- Engineer high throughput and predictable latency, jitter, and packet loss through capacity planning, QoS, traffic engineering, and system tuning.
- Align network redundancy and convergence with host clustering, application failover, storage replication, and recovery time and recovery point objectives.
- Design failure domains and diverse paths; validate service behaviour during peak load, maintenance, and link, device, host, or site failures.
- Define service-level indicators and objectives, telemetry, and performance baselines spanning network and systems components.
- Architect network security controls in partnership with the security team, including segmentation, zero-trust access, firewalling, DDoS mitigation, MACsec and IPsec encryption, and secure management-plane design.
6. Technical Leadership and Delivery
- Lead design reviews, proofs of concept, migrations, and production readiness across infrastructure, platform, security, and application teams.
- Produce reference configuration snippets for each design and prove them in a lab or proof-of-concept environment on target platforms, demonstrating the design is workable and operational before handover to engineering for full build and rollout.
- Guide complex fault isolation across physical, optical, network, operating system, and platform layers, working with domain specialists.
- Mentor engineers, maintain clear design and operational documentation, and explain architectural decisions to technical and non-technical stakeholders.
- Act as the senior technical escalation point for complex or major network incidents, participating in on-call escalation as required, and lead post-incident reviews that identify systemic and architectural root causes, resolving them through corrections to reference designs, standards and permanent corrective actions.
7. Automation and AI Operations
- Champion network automation and NetDevOps practices, including infrastructure as code using Terraform and Ansible, a network source of truth, CI/CD pipelines for configuration changes, pre-change validation and streaming telemetry, driving configuration consistency and lifecycle management across the estate.
- Define the architecture and governance for AI-assisted network operations, including AI agents connected to network automation, telemetry and source-of-truth platforms through the Model Context Protocol (MCP), with guardrails such as read-only defaults, human approval for changes, role-based access and audit logging.
8. Vendor and Commercial Management
- Own the Request for Proposal (RFP) process with OEMs and partners, defining technical requirements, evaluation criteria and scoring models to give full visibility of competing solutions and a like-for-like technical and commercial comparison.
- Shape vendor and carrier strategy, providing input to commercial negotiations and managing strategic OEM, partner and carrier relationships.
