• Monitor and troubleshoot pipelines, batch processes, and production data environments. 

• Apply security, governance, access-control, and credential-management best practices. 

• Improve pipeline resilience through effective monitoring, error handling, restartability, and recovery. 

• Optimise data workloads for performance, scalability, and cost. 

• Develop reusable components and patterns for ingestion, transformation, validation, and monitoring. 

• Prepare governed and trusted datasets for analytics, reporting, AI, and machine-learning use cases. 

• Collaborate with clients and internal stakeholders to translate business requirements into practical technical solutions. 

• Identify opportunities to modernise legacy processes, reduce manual effort, and improve operational efficiency. 

• Maintain technical documentation, data lineage, business rules, and operational runbooks.
