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). 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. Technical 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 covered Key 2 locations : Existing DMZ infrastructure all exists in London and Manchester, so ideally either of those. Operational Requirements Reporting 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, emails Knowledge Transfer / Handover Expectations when Service Concludes: Fully documented knowledge articles/handover
