• Data quality and reliability:Implement automated data quality checks, validations and controls that prevent bad data from silently reaching consumers.
• Performance and cost optimisation:Actively tune Spark workloads, storage layouts and execution patterns with an awareness of cloud cost and runtime behaviour.
• Dual-run and migration delivery:Support and stabilise existing Synapse workloads while contributing to migration and net-new delivery on Databricks.
