Role Summary
We are seeking a Technical Architect to lead the design and assurance of a large-scale, real-time data aggregation platform delivering open, secure and standards-compliant digital services for government, industry, and consumers.
This role will support the end-to-end architecture lifecycle, from Discovery through to BAU, ensuring the solution meets non-functional requirements for real-time data ingestion, validation, aggregation, and dissemination. The platform will be accessed by a wide spectrum of stakeholders, including commercial organisations, regulated entities, and government authorities.
You will collaborate with multi-disciplinary teams to deliver a cloud-native, API-first solution, incorporating multiple input channels and enforcing strict data quality, governance, and availability SLAs.
Requirements
Key Responsibilities
Discovery & Design

• Lead technical discovery, mapping the current state and identifying suitable architectural approaches for real-time data aggregation and distribution.
• Design secure, resilient architecture across infrastructure, applications, data pipelines, APIs, and user access.
• Evaluate and recommend technologies for multi-channel input (e.g. API, web, IVR, SMS) and automated validation against business rules and compliance thresholds.
• Produce architecture deliverables including HLDs, LLDs, interface specifications, data flows, security zones, and deployment models.

Alpha & Beta Phases

• Define and evolve prototypes for service components in line with government service standards.
• Architect the back-end for ingesting, cleansing, validating and aggregating structured data at national scale.
• Implement modular, microservices-based patterns supporting interoperability and scalable integration.
• Collaborate with DevOps teams to build CI/CD pipelines, test automation, IaC, and container orchestration.
• Define SLAs, KPIs, and technical acceptance criteria for Alpha and Beta service assessments.
• Support accessibility and usability alignment with WCAG and GOV.UK standards.

Public Launch & BAU

• Finalise architectural patterns for live rollout and BAU support, ensuring regulatory and security compliance.
• Define observability architecture, including real-time monitoring, logging, anomaly detection, and alerting.
• Support governance boards and internal service assessments through the provision of architectural documentation and assurance.
• Lead technical response to incidents, performance tuning, and compliance testing (e.g. penetration testing, accessibility audits, disaster recovery).
• Guide change control, scalability reviews, and future enhancements post go-live.

Essential Skills & Experience

• Extensive experience (5+ years) as a Technical Architect designing and delivering digital platforms for public services, regulated data, or open data sharing.
• Strong background in cloud-native architecture (AWS/Azure/GCP), with hands-on understanding of:

• Event-based and batch data ingestion
• Secure API design, throttling, caching, OpenAPI standards
• High-availability architectures with resilience and failover

• Identity and access management frameworks (OAuth2, RBAC)
• Data lineage, metadata, governance and retention
• Service level management (SLAs, KPIs, thresholds, alerts)

Desirable Skills

• Experience with real-time public-facing data services, regulatory data platforms, or high-volume open data feeds.
• Experience of cross-departmental digital transformation, including interaction with enforcement bodies and data consumers.
• Knowledge of government assurance processes including internal governance boards, DPIAs, and service spend approvals.
• Exposure to observability tooling, data quality dashboards, and continuous service improvement practices.

Qualifications

• Degree in Computer Science, Engineering, or equivalent experience.
• Certifications such as TOGAF, AWS Certified Solutions Architect, Azure Solutions Architect Expert, or equivalent.
