Lead Data Architect

Lead Data Architect
London, United Kingdom

What you'll be doing:
We are seeking a Data Architect to lead the design and delivery of secure, cloud-based data
platforms for UK Central Government departments. The role combines architectural strategy
with delivery oversight – shaping target-state architectures while ensuring they are implemented
pragmatically within regulated, security-conscious environments.
This position will suit an architect who can move comfortably between traditional enterprise

data approaches and modern patterns such as lakehouse, streaming, data mesh and ML-
enabled platforms – and who values clarity, governance and technical rigour.

Candidates must be eligible for SC clearance (existing SC clearance desirable).

What experience you'll bring:
Leadership:
• Recent experience as a Lead Data Architect / Data Solutions Architect or equivalent
senior role.
• Demonstrated ownership of end-to-end data platform design and delivery.
• Experience operating in consulting, systems integration, or delivery partner roles.
• Experience working within UK Central Government or ALBs strongly preferred.
Modern and Enterprise Data Architecture:
You should have practical architecture experience across both established enterprise
approaches and modern data patterns, including:
• Cloud-native data platforms (AWS, Azure, GCP).
• Snowflake, Microsoft Fabric, and/or SageMaker (multi-platform experience
advantageous).
• Data lake and lakehouse architectures.
• Event-driven and streaming architectures.
• Data Mesh and/or Data Fabric principles (applied pragmatically, not theoretically).
• Data product-oriented design approaches.
You understand where traditional patterns remain appropriate – and where modern approaches
add measurable value.
Data Engineering & Platform Understanding:
• Strong knowledge of distributed processing (e.g. Apache Spark).
• Familiarity with Hadoop ecosystem components.
• Working knowledge of SQL and NoSQL technologies.
• Understanding of ETL/ELT design trade-offs.
• Awareness of DevOps practices and CI/CD for data platforms.
• Understanding of how ML/AI workloads integrate into data architectures.
Hands-on coding ability (e.g. Python, Java, R) is beneficial but not required.
Governance, Security and Data Management

• Experience designing within structured architectural governance frameworks.
• Familiarity with government assurance processes and design authorities.
• Strong understanding of data governance frameworks and metadata management.
• Experience designing for GDPR and UK public sector data protection requirements.
• Appreciation of infrastructure considerations and security boundaries in regulated
cloud environments.
Stakeholder Engagement
• Ability to influence architectural direction at senior stakeholder level.
• Clear and structured communicator — able to explain trade-offs and risks.
• Experience leading and mentoring architects and engineers.
• Comfortable operating within programme governance structures.
• Familiarity with Agile delivery models (SAFe, Scrum, Kanban).
