Key Responsibilities 1. Lead Architecture for Brownfield Modernisation

• Analyse and reshape the existing architecture to support new upstream microservices and evolving schema definitions (300+ schemas).
• Design approaches for merging 3-5 years of historical data with newly structured data while maintaining consistent user journeys.
• Identify modernisation pathways that minimise disruption to live services.

2. Data Platform & Integration Architecture

• Define new and/or modify ingestion, transformation, and storage patterns suitable for microservice-based upstream systems.
• Ensure downstream services maintain data quality, lineage, and continuity during schema transitions.
• Design data migration strategies and transient approaches supporting phased, low-risk rollouts.

3. Infrastructure, Security & Network Architecture

• Define the infrastructure and security requirements for safe and compliant connectivity between AWS-hosted services and Azure-hosted DWP environments (e.g., SaSViya).
• Ensure the confidentiality, integrity, and controlled movement of sensitive data across cloud boundaries.

4. Technology Modernisation & Standards Alignment

• Assess existing technology choices (e.g., Kotlin) and recommend migration paths aligned to DWP-approved standards.
• Produce clear technical options, roadmap recommendations, and architectural decision records.
• Advocate for simplification, reduction of technical debt, and alignment to Digital Blueprint and Enterprise Architecture.

5. Leadership, Governance & Stakeholder Engagement * Act as the senior architectural authority across related services. Skills & Experience Required Essential

• Deep understanding of government, public sector, or regulated environments.
• Strong experience of technical authority, security governance and SRE handover
• Experience maintaining critical services while modernising underlying platforms.

• Ability to navigate and implement organisational standards

Hands-on experience re-architecting or migrating technology stacks to standardised platforms.

• Exceptional communication & leadership: able to drive clarity and decision-making in ambiguous contexts.
• Strong experience of technical documentation on Confluence/SharePoint

Desirable

• Experience with event-driven architectures and microservice-based data contracts.
• Knowledge of Kotlin and migration pathways to DWP-standard languages (Java, Python, etc.).
