* Real-time processing: Implement and optimise streaming workloads using Kafka, Event Hub and Spark Streaming to ensure low-latency data availability for life-critical monitoring.
* Governance & compliance: Enforce strict data quality frameworks and maintain PII/PHI compliance, ensuring the integrity of sensitive healthcare and operational data.
* Visualisation & reporting: Collaborate with stakeholders to design and deploy the “Master Dashboard” using Power BI, utilising DAX and semantic models for actionable insights.
*Requirements:*
* Azure mastery: Deep expertise in the Azure Ecosystem, specifically Databricks, Azure Data Factory (ADF), Synapse and Unity Catalog.
* Data engineering: Proficiency in Python, PySpark and Spark SQL for ETL/ELT pipeline development.
* Time-series expertise: Proven experience handling real-time, high frequency data feeds (e.g. aviation, sensor or industrial data)
* Schema design: Advanced knowledge of Star and Snowflake Schemas and Lakehouse architectures.
* Quality assurance: Hands-on experience with data validation tools like Great Expectations and observability platforms like Grafana.
* DevOps: Familiarity with CI/CD processes using Azure DevOps or GitHub Actions.
*Preferred Qualifications:*
* 6+ years of experience in data engineering with a focus on resilient, high availability systems.
