What You’ll DoAssess the existing data landscape, including source systems, data flows, interfaces, dependencies and workloads.Define the target architecture across data ingestion, storage, transformation, modelling and consumption.Design raw/landing, curated and business-consumption data layers.Establish patterns for batch, incremental and near-real-time ingestion into AWS and Snowflake.Guide the migration of data pipelines, transformations and workloads from on-premises platforms.Define standards for enterprise data products, analytical models and semantic layers.Establish data quality, reconciliation, lineage, metadata and governance requirements.Define security controls covering RBAC, encryption, masking, privacy and auditability.Set requirements for performance, scalability, availability, recoverability, observability and cost optimisation.Establish Snowflake performance and FinOps principles, including warehouse sizing, workload isolation and query optimisation.Define operational-readiness requirements, including monitoring, alerting, runbooks and managed-service handover.Provide technical leadership, design assurance and architecture governance throughout delivery.
What You’ll BringStrong hands-on Snowflake architecture experience, including warehouses, databases, schemas, tables, views, stages, Snowpipe, Streams and Tasks.Strong AWS data architecture knowledge across ingestion, storage, data lake and integration services.Deep understanding of data warehousing, lake/lakehouse architecture, ETL/ELT and data integration.Experience designing migrations from on-premises platforms to cloud-based data platforms.Strong dimensional and relational modelling skills, including data products and semantic layers.Experience with data quality, reconciliation, metadata, lineage, cataloguing and governance.Knowledge of IAM/RBAC, encryption, masking, privacy controls and secure data architecture.Experience with CI/CD, DataOps and automated deployment patterns.Strong Snowflake performance engineering and cloud cost-optimisation expertise.The ability to produce target-state architectures, migration designs, data-flow diagrams, architecture standards, decision records and reusable patterns.Experience defining operational-readiness, monitoring and production-support models.Strong stakeholder engagement skills across business, data, security, risk, engineering and operations teams.Banking, financial services or highly regulated enterprise experience is strongly preferred.Snowflake and AWS architecture or data engineering certifications are highly regarded.Experience with TOGAF, Power BI, enterprise semantic models, data catalogue platforms or integration tooling would be advantageous.
Why Apply?This is a high-impact opportunity to shape the future data architecture of a major banking environment, work with modern Snowflake and AWS technologies, and guide a complex transformation from design through to production.
If you are an experienced Data Architect with strong Snowflake, AWS and data-modernisation expertise, we would welcome your application.
