Role Overview
We are seeking an experienced Hybrid Cloud & Network Security Architect to lead the design and definition of a secure, scalable hybrid cloud edge and DMZ hosting architecture. The role is architecture-led and outcome-focused, responsible for defining target state designs, security controls, governance alignment, and delivery planning to enable future migration phases.
This is a hands-on architecture and design role, not an implementation-only position.
Key Objectives & Outcomes
Business Objectives (what outcomes are you looking to achieve through this service):
· Target Architecture Document for cloud edge and DMZ hosting (including diagrams, logical and physical topology).
· Hybrid Connectivity Design Principles and Standards (DNS-based policy, Zero Trust segmentation, firewalling).
· Detailed Bill of Materials (vendor/platform options, sizing, licence models, costs to Class 4 estimate).
· Delivery Project Plan (work breakdown structure, stage gates, dependencies, critical path).
· Security & Compliance Controls mapping (ISO 27001, NIST, GDPR alignment).
· Risk Register and Mitigation Plan (including security risks during migration).
· Stakeholder Engagement & Governance Plan (EICTH Futures tollgates, comms plan).
· Migration Strategy outline (phasing, cutover options, rollback), to inform later phases.
In-Scope Activities:
· Establish full inventory of services impacting hybrid flows and analyse existing traffic patterns.
· Target architecture design for cloud edge, DMZ hosting model, and hybrid connectivity (including DNS-based policy enablement).
· Network & security BoM definition (hardware, software, licences), and delivery project plan with stage gates.
· Liaison with internal teams (Digital Distribution, Connectivity, Architecture, InfoSec, Service Assurance, Commercial) to define cross-connects, circuits, and governance alignment.
· Assessment of hyperscaler scope (AWS in baseline; Azure/GCP to be evaluated) and interconnection locations (carrier-neutral DCs/IX presence).
