• Develop curated data models in a medallion (bronze/silver/gold) architecture using Delta Lake, ensuring data quality, lineage, and reusability across analytics and AI use cases
• Develop and optimise SQL and PySpark transformations for high-volume datasets, with strong attention to performance, cost, and reliability
• Operationalise pipelines through Azure DevOps and/or GitHub Actions, embedding automated testing, deployment, and observability into the data delivery lifecycle
• Implement data quality checks, monitoring, and alerting across critical data products, working with platform engineering on lineage and cataloguing (e.g., Microsoft Purview, Unity Catalog)
• Collaborate with data architects to align pipelines with the enterprise data model and governance standards, including PII handling, retention, and access controls relevant to insurance regulation
• Work closely with analytics, actuarial, and data science teams to translate business requirements into robust data products and self-service datasets
• Participate in code reviews, design sessions, and Agile ceremonies, contributing to engineering standards and continuous improvement of the data platform

Requirements

• Bachelor's degree in Computer Science, Information Systems, Engineering, or a related technical field
• 3-5 years of hands-on experience as a Data Engineer or in a closely related role, delivering production data pipelines
• Proven track record of building cloud-native data solutions in Agile/Scrum environments
• Strong experience with Microsoft Azure data services: Azure Data Factory, Azure Synapse Analytics, Azure Data Lake Storage Gen2, and Azure SQL
• Hands-on experience with Databricks and Apache Spark (PySpark), including Delta Lake and the medallion architecture
• Advanced SQL skills and solid Python development for data engineering workloads
• Familiarity with CI/CD pipelines using Azure DevOps and/or GitHub Actions, infrastructure-as-code (Terraform or Bicep), and Git-based workflows
• Understanding of data modelling (dimensional, Data Vault, or lakehouse patterns) and data governance concepts including data quality, lineage, and security

Nice to have:

• Experience in regulated industries (insurance, banking, healthcare
• Working knowledge of Google Cloud data services
