• Support data migration and modernisation programmes, including lifting and shifting legacy data warehouses, consolidating data domains and enabling self-service analytics

• Ensure solutions meet regulatory, compliance and security requirements relevant to banking and financial services (e.g. GDPR, local reporting, auditability)

• Produce high-quality architecture artefacts, technical specifications, runbooks and operational documentation for stakeholders and support teams

• Engage with client stakeholders to translate business requirements into technical designs and pragmatic implementation roadmaps
