Design and implement agentic workflows that coordinate data preparation, quality validation, metadata generation, dashboard updates and operational support.
Build and maintain CI/CD pipelines using GitHub Actions.
Design data models, ontologies, taxonomies and common data definitions.
Implement data matching, entity resolution, deduplication and data cleansing solutions.
Build automated data quality, validation, reconciliation and observability controls.
Develop solutions for large and complex datasets using big data and distributed processing technologies.
Support the productionisation and monitoring of machine learning and open-weight models.
Develop production-grade solutions using Python and/or R.
Establish engineering standards, mentor engineers and provide technical guidance.
Ensure data solutions meet security, privacy, resilience and governance requirements.
