We are looking for an experienced Senior Data Engineer to join a Data & Analytics (DnA) team. You will design, build, and operate production-grade data products across customer, commercial, financial, sales, and broader data domains. This role is hands-on and heavily focused on Databricks-based engineering, data quality, governance, and Dev Ops-aligned delivery.

You will work closely with the Data Engineering Manager, Product Owner, Data Product Manager, Data Scientists, Head of Data & Analytics, and IT teams to transform business requirements into governed, decision-grade datasets embedded in business processes and trusted for reporting, analytics, and advanced use cases.

• Design, build, and maintain pipelines in Databricks using Delta Lake and Delta Live Tables.
• Implement medallion architectures (Bronze/Silver/Gold) and deliver reusable, discoverable data products.
• Ensure pipelines meet non-functional requirements such as freshness, latency, completeness, scalability, and cost-efficiency.
• Own and operate Databricks assets including jobs, notebooks, SQL, and Unity Catalog objects.
• Apply Git-based Dev Ops practices, CI/CD, and Databricks Asset Bundles to safely promote changes across environments.
• Implement monitoring, alerting, runbooks, incident response, and root-cause analysis.
• Enforce governance and security using Unity Catalog (lineage, classification, ACLs, row/column-level security).
• Define and maintain data-quality rules, expectations, and SLOs within pipelines.
• Support root-cause analysis of data anomalies and production issues.
• Partner with Product Owner, Product Manager, and business stakeholders to translate requirements into functional and non-functional delivery scope.
• Collaborate with IT platform teams to define data contracts, SLAs, and schema evolution strategies.
• Produce clear technical documentation (data contracts, source-to-target mappings, release notes).

• 6+ years in data engineering or advanced analytics engineering roles.
• Strong hands-on expertise in Python and SQL.
• Proven experience building production pipelines in Databricks.
• Excellent attention to detail, with the ability to create effective documentation and process diagrams.
• Solid understanding of data modelling, performance tuning, and cost optimisation.

• Hands-on experience with Databricks Lakehouse, including Delta Lake and Delta Live Tables for batch/stream pipelines.
• Knowledge of pipeline health monitoring, SLA/SLO management, and incident response.
• Unity Catalog governance and security expertise, including lineage, table ACLs, and row/column-level security.
• Familiarity with Databricks Dev Ops/Data Ops practices (Git-based development, CI/CD, automated testing).
• Performance and cost optimization strategies for Databricks (autoscaling, Photon/serverless, partitioning, Z-Ordering, OPTIMIZE/VACUUM).
• Semantic layer and metrics engineering experience for consistent business metrics and self-service analytics.
• Experience with cloud-native analytics platforms (preferably Azure) operating as enterprise-grade production services.
