To be successful in this role, we are looking for candidates with the following qualifications and attributes:

• A degree in Computer Science, Information Technology, Business Information Technology, Data Engineering or a comparable field, or equivalent professional experience.
• 5+ years of relevant experience in data engineering, including substantial hands‑on experience with Microsoft Azure or another major cloud platform.
• Hands‑on experience with modern data platforms such as Microsoft Fabric, Azure Synapse Analytics, Databricks or Snowflake.
• Strong SQL skills and practical experience with Python for data engineering, automation or testing.
• Strong understanding of modern data architectures, including data warehouses, data lakes and Lakehouse patterns.
• Strong data‑modelling skills, particularly relational and dimensional modelling; familiarity with additional modelling approaches is beneficial.
• Ability to design, troubleshoot and optimize data transformations, SQL workloads and data pipelines for performance, reliability and maintainability.
• Experience with Power BI, semantic models or comparable analytics and visualization technologies is an advantage.
• Experience with Git, automated testing and CI/CD practices for data and analytics solutions.
• Experience with relevant Azure services such as Azure Data Factory, Azure Functions, Logic Apps, Synapse Analytics or Azure Automation is an advantage.
• Knowledge of streaming, event‑driven architectures or real‑time analytics is an advantage.
• A collaborative and proactive mindset, strong communication skills, and the ability to take ownership while continuously learning and sharing knowledge.
