• Cloud Platform Architecture
• Define and maintain target-state architecture for Microsoft Azure, cloud and hybrid technology platforms.
• Define reference architectures and reusable patterns for Azure landing zones, Management Groups, subscriptions, networking, identity, compute, storage, monitoring and governance.
• Establish architectural principles and guardrails covering Azure Policy, RBAC, PIM, private connectivity, resource organisation, logging and platform governance.
• Define architecture patterns that enable scalable, secure and consistent technology delivery across FSCS.
• Provide architectural direction for cloud migration, modernisation and re-platforming initiatives.
• Assess new Azure services and cloud technologies and provide recommendations for their adoption.
• Ensure cloud architecture balances security, resilience, scalability, performance, operational supportability and cost efficiency.
• Define architectural direction for Infrastructure as Code and automated cloud provisioning, including Terraform and Azure Dev Ops.
• Hybrid Infrastructure Architecture
• Define target-state architecture for FSCS hybrid infrastructure and its integration with Microsoft Azure.
• Define target-state architectural patterns and standards for core infrastructure services, including technologies such as Active Directory, Entra ID, DNS, DHCP and PKI.
• Provide architectural direction for compute, virtualisation, storage and associated platform technologies.
• Define secure and resilient integration patterns between cloud, on-premises and third-party environments.
• Develop architecture roadmaps supporting infrastructure modernisation and reduction of legacy technology.
• Identify architectural dependencies, constraints and technical debt associated with hybrid infrastructure.
• Network & Connectivity Architecture
• Define target-state network architecture across cloud and hybrid environments.
• Define reference architectures and patterns for Azure networking, routing, segmentation, firewalls, private connectivity, VPN, load balancing and application delivery.
• Define network architecture aligned with FSCS Zero Trust principles and security requirements.
• Provide architectural direction across Azure networking, Cisco technologies, Zscaler and associated network and security platforms.
• Define secure connectivity patterns between Azure, on-premises infrastructure, Saa S services, third parties and external services.
• Establish architecture standards and principles for network resilience, segmentation, availability and secure connectivity.
• Security Architecture & Technical Controls
• Define cloud platform and infrastructure security architecture aligned with FSCS security policies, enterprise architecture principles and regulatory requirements.

• Provide architectural direction for Microsoft Defender, Sentinel and associated Microsoft security technologies.
• Define identity architecture covering Entra ID, Conditional Access, PIM, RBAC, MFA, SSO, managed identities and workload identities.
• Define architectural patterns for Azure Firewall, WAF, DDo S Protection, Key Vault, encryption, certificates and secrets management.
• Define architecture patterns aligned with Zero Trust principles across identity, networks, applications and cloud platforms.
• Ensure security, vulnerability management, hardening, logging and monitoring requirements are incorporated into reference architectures and solution designs.
• Work closely with Information and Cyber Security to ensure platform architectures align with security policies, standards and risk requirements.
• Resilience, Backup & Disaster Recovery
• Define architecture principles and patterns for availability, resilience, backup, recovery and disaster recovery.
• Define appropriate resilience and redundancy patterns for critical cloud and hybrid platforms.
• Ensure architecture supports agreed recovery objectives and operational resilience requirements.
• Define reference architectures for backup, replication, failover and recovery capabilities.
• Identify architectural risks and single points of failure and recommend appropriate design improvements.
• Architecture Governance & Design Authority
• Act as a key member of the Technology Design Authority and relevant architecture governance forums.
• Define and maintain cloud platform, infrastructure and security architecture principles, standards, reference architectures and patterns.
• Provide architectural review and design assurance for technology solutions and major changes.
