• Embed automated validation checks, data quality rules and lineage controls to support governance and trust in the data.
• Prepare clean, structured, production-ready datasets for dashboards, analytics and modelling.
• Work closely with Data Analysts and wider stakeholders to ensure data is available, complete and fit for purpose.
• Create and maintain clear documentation for pipelines, integration flows and core data structures.
• Identify opportunities to automate manual processes, improve efficiency and support continuous improvement across the data platform.
• You'll also contribute to the ongoing evolution of ND&I's data engineering practices, helping us build a modern, resilient and insight-led data environment.

• Strong hands-on experience building ETL/ELT solutions in cloud-based data environments.
• Proficiency in SQL and Python, or equivalent scripting languages used in data engineering.
• Experience with cloud data platforms and orchestration tools such as GCP, Snowflake, Airflow or Azure Data Factory.
• Good understanding of data modelling, data warehousing and integration patterns.
• Experience embedding data quality, validation and lineage controls into engineering processes.
