Data Architect
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).
