Job Description

Contract: 3 months (initial)

Daily rate: £700

Location: Onsite – London (primary), with engagement across London & Manchester environments

Working Hours: 9:00–17:00, Monday to Friday

Engagement Type: Contract

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).
