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 & OutcomesBusiness 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).Deliverables or KPI’s (e.g. uptime %, response times, resolution targets, etc) • 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.RequirementsTechnical Environment Key Technologies, Platforms or Vendors where experience is required:• Core Networking• Enterprise LAN/WAN/SD-WAN architecture and design.• Routing & switching (L2/L3), Wi-Fi controllers/enterprise deployments.• Network performance engineering (capacity planning, QoS, traffic engineering).• Security Expertise• Firewalls, VPNs, IDS/IPS, secure segmentation, Zero Trust architecture.• Threat detection/response, SIEM integration, incident response.• Compliance frameworks (ISO 27001, NIST, GDPR).• Cloud & Hybrid Networking• AWS/Azure/GCP networking (VPC/VNet, Transit Gateway, cloud firewalls).• Hybrid integration, secure tunnels, SASE/SD-WAN.• Platforms & Tools• Cisco, Arista, Aruba, ClearPass, Infoblox, Mist, Fortinet, Check Point.• Security Service Edge (Zscaler ZIA, ZPA, ZDX, ZIdentity, Cloud/Branch Connector).• Monitoring/automation (SNMP, NetFlow, Ansible, Terraform); packet analysis (Wireshark).• Soft Skills• Stakeholder communication, documentation/reporting, leadership/mentoring.Number of locations / Sites coveredKey 2 locations : Existing DMZ infrastructure all exists in London and Manchester, so ideally either of those.Operational RequirementsReporting Requirements (Monthly Reporting / Dashboards / Reviews):• Regular stand up meetings and ad hoc project meetings• Programme governance: EICTH Futures; tollgates for key decisions/milestones.• Weekly status report: progress, risks/issues, decisions required.• Stakeholder reviews: Architecture (TDA), InfoSec, Service Assurance, Commercial.Communication Channels (Teams / Slack / Ticketing / Emails):MS Teams, emailsKnowledge Transfer / Handover Expectations when Service Concludes: Fully documented knowledge articles/handover
