• Apply dbt for transformation of ingested data within the Snowflake environment
• Monitor, troubleshoot, and optimise integration pipelines for performance and reliability
• Document integration architecture and maintain data lineage across the pipeline estate

• Hands‑on Fivetran experience: connector configuration, pipeline management, and troubleshooting
• Strong Snowflake experience: understanding of how data lands, is structured, and is consumed
• Experience with dbt for data transformation within a Snowflake environment
• Understanding of modern ELT architecture and data pipeline design principles
• Experience migrating or replacing legacy integration platforms (Mulesoft, Informatica, SSIS, or similar)
• Ability to work across technical and business stakeholders in a programme environment
• Python scripting for automation or custom connector development

Nice to Have

• Direct Mulesoft experience: understanding the existing landscape being replaced is a significant advantage
• Experience with Census or similar reverse ETL tooling
• Familiarity with event‑driven integration patterns (Kafka, Azure Event Hubs)
• Retail or e‑commerce domain experience
