At CGI, you’ll help clients modernise critical data landscapes through secure, controlled migration to the cloud. As a Senior Data Architect, you’ll shape migration strategy, define ETL approaches and ensure data quality, governance and resilience are built into every stage of delivery. Working closely with multidisciplinary teams, you’ll translate complex technical needs into practical solutions that deliver measurable outcomes.
