We are seeking a Lead Data Migration Architect to lead the design, assurance, and delivery of secure, cloud‑based data migration solutions for UK Central Government departments. The role combines architectural strategy with hands‑on migration delivery oversight and testing governance, shaping target‑state data platforms while ensuring data is migrated accurately, securely, and efficiently within regulated, security‑conscious environments.
This role places a strong emphasis on data migration validation, ETL testing, and pipeline assurance, particularly within AWS‑based Data Lakehouse architectures. You will be responsible for defining and governing end‑to‑end migration testing strategies, ensuring successful transition of data from legacy data warehouses to modern cloud platforms. This position will suit an architect who can operate across both enterprise data architecture and modern cloud‑native migration patterns, and who values precision, data quality, governance, and technical rigour. Candidates must be eligible for SC clearance (existing SC clearance desirable; BPSS minimum required).
Responsibilities- Design end‑to‑end data migration architectures from legacy systems to cloud platforms.
- Define migration strategies including bulk data loads followed by incremental/delta processing, and re‑platforming and repointing of data pipelines.
- Lead migration programmes from legacy data warehouses to AWS Data Lakehouse architectures.
- Design migration frameworks covering data extraction, transformation, and loading (ETL/ELT); data staging, reconciliation, and validation; migration orchestration and monitoring.
- Define and govern end‑to‑end migration testing strategies.
- Testing end‑to‑end ETL/ELT data pipelines on AWS, including AWS Glue‑based solutions.
- Validate data feed pipeline migrations and repointing to new AWS Data Lakehouse architectures.
- Oversee testing of pipelines underpinned by AI ETL accelerators, Python/PySpark, SQL transformations, and YAML‑driven configuration frameworks.
- Validate bulk migration loads followed by incremental/delta data processing from legacy data warehouses.
- Define and implement data reconciliation frameworks, data completeness and accuracy checks, transformation validation rules, and regression testing across migration cycles.
- Establish automated testing frameworks for large‑scale data migration assurance.
- Strong experience with AWS cloud‑native data platforms, including AWS Glue, S3‑based data lakes, and Lakehouse architectures using Apache Iceberg.
- Familiarity with data lake and lakehouse patterns; event‑driven and streaming architectures where relevant to migration.
- Understanding of where modern migration approaches add value versus traditional ETL patterns.
- Tailored benefits that support your physical, emotional, and financial wellbeing.
- Learning and Development opportunities for continuous growth and development.
- Flexible work options.
- Recent experience as a Lead Data Migration Architect, Lead Data Architect, or Data Solutions Architect in migration‑focused programmes.
- Demonstrated ownership of end‑to‑end data migration strategy, execution, and testing assurance.
- Experience operating in consulting, systems integration, or delivery partner roles.
- Proven leadership of cross‑functional migration teams, including engineers, testers, and architects.
- Experience working within UK Central Government or ALBs strongly preferred.
