- You’ll design and build of data observability and data quality by design into all Data pipelines, promoting self-testing pipelines that proactively identify processing issues or discrepancies.
- You’ll build solutions that pipe transform data into data lake storage areas, physical database models and reporting structures across data lake, data warehouse, business intelligence systems and analytics applications.
- You’ll build physical data models that are appropriately designed to meet business needs and optimise storage requirements, ensuring maximum re-use.
- You’ll carry out unit testing of own code, peer testing of others code to ensure appropriate quality, and be responsible for completeness and integrity of solutions delivered on the data platform(s).

- Synapse Analytics - Experience designing and implementing tables, schemas, stored procedures and data models within Synapse dedicated SQL pools, with knowledge of Synapse architecture and performance.
- Version Control & CI/CD – Expertise in Git-based workflows and CI/CD for data platforms, including branching strategies and automated deployments via YAML pipelines.
- Unit Testing – Experience implementing unit testing for data pipelines to ensure code quality and reliability.
- Data Architecture – Experience designing and implementing data models within modern lakehouse architectures, including dimensional modelling (Kimball) for scalable analytics.
- Data Quality – experience embedding data quality by design into data pipelines, incorporating validation rules, cleansing, and transformation logic to deliver trusted, high-quality data products.
- Azure Cloud Architecture – Experience designing and governing secure, scalable Azure environments, leveraging network isolation (Virtual Network, Private Link, Firewall), identity and access controls (RBAC, PIM), and effective resource organisation (subscriptions, resource groups, tagging, cost management).
- Microsoft Entra ID – Experience in implementing identity and access management for cloud data platforms, including security groups and service principals for secure authentication and authorisation.
- Infrastructure-as-Code – Experience designing and implementing infrastructure using declarative approaches (e.g. Terraform, Bicep), enabling automated, repeatable, and consistent cloud deployments.
