Role Profile: Data Migration Architect
The Data Migration Architect is responsible for defining, leading, and assuring the end-to-end migration of complex enterprise data from a legacy platform to modern cloud-based architecture. This role combines technical expertise with architectural leadership, governance, and stakeholder engagement to ensure successful, secure, and efficient data migration solution.
Key Responsibilities
- Lead the design and delivery of large-scale data migration, including the migration of high-volume, complex datasets (e.g. ~400GB) from a legacy Oracle data architecture to a more decomposed, cloud-based PostgreSQL environment.
- Provide architectural leadership to extend and refine existing approved High-Level Designs (HLDs), ensuring robust, scalable, and future-proof solutions for evolving data migration requirements.
- Guide and support data engineering teams, ensuring development aligns with agreed architectural patterns and standards, and any required design changes are appropriately made and governed.
- Collaborate closely with client stakeholders to define and agree solutions across security architecture, development, and testing within AWS cloud environments.
- Act as the solution owner for data migration, coordinating across client and third-party organisations to ensure technical integrity, security, development and testing, ultimately leading to successful delivery of the data migration solution.
- Lead architecture governance activities within programme and enterprise forums including presenting solutions to client governance boards such as security, data, and technical design authorities.
- Work in partnership with delivery management to identify and manage technical dependencies across the wider programme, ensuring alignment and timely resolution.
