Enterprise Architect - Tech Resilience

Years of Experience Minimum 10 years in infrastructure, solution or enterprise architecture, including at least 5 years in technology resilience, high availability and disaster recovery architecture. Key Responsibilities • Provide technical architecture support for the definition and evolution of the enterprise resilience and failover architecture. • Assess the current resilience and failover architecture across relevant applications, platforms, infrastructure and dependencies. • Identify architectural bottlenecks, single points of failure, recovery constraints and cross-site dependency risks. • Develop target-state resilience and failover architecture options aligned with rapid recovery objectives. • Evaluate technical options and trade-offs covering availability, recoverability, operability, complexity, cost and implementation risk. • Work with Enterprise Architecture, Technology Platforms, DR/Operations, Cyber Security and application owners to validate architecture assumptions and requirements. • Produce architecture artefacts and recommendations for governance review; operational implementation and DR test execution remain with the accountable platform and operations teams. Required Skills • Strong architecture experience in enterprise resilience, disaster recovery, high availability and failover design. • Knowledge of active-active, active-passive, multi-site and multi-region architecture patterns. • Ability to assess end-to-end application, infrastructure, network, data, integration and cloud dependencies. • Experience defining RTO/RPO-aligned architecture and analysing recovery failure modes. • Strong stakeholder facilitation, technical option assessment and architecture documentation skills. • Experience in regulated financial services or similarly critical environments is strongly preferred. Key Deliverables • Current-state resilience and failover architecture assessment. • Documented architecture risks, bottlenecks, dependency gaps and prioritized remediation considerations. • Target-state resilience and failover architecture covering applications, platforms, infrastructure and critical technology dependencies. • Technical options paper with trade-offs, recommendation and implementation dependencies. • Architecture roadmap and transition considerations for the agreed target state. • Governance-ready architecture pack, architecture decisions and recommendations supporting target-state approval and implementation planning. Certifications & Technical Requirements Certifications Preferred: TOGAF certification and relevant cloud architecture certification such as AWS Certified Solutions Architect or Microsoft Certified: Azure Solutions Architect Expert. Business continuity or resilience certification such as CBCI is advantageous. Preferred Tech Stack Hybrid infrastructure; cloud platforms; virtualization; container platforms; databases; storage and replication; network and load-balancing technologies; enterprise integration and observability capabilities. Tools / Platforms ServiceNow CMDB; Jira; Confluence; Microsoft 365.
