About the Role
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 DevOps-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.
Key Responsibilities
1. Design, build, and maintain pipelines in Databricks using Delta Lake and Delta Live Tables.
2. Implement medallion architectures (Bronze/Silver/Gold) and deliver reusable, discoverable data products.
3. Ensure pipelines meet non-functional requirements such as freshness, latency, completeness, scalability, and cost-efficiency.
4. Own and operate Databricks assets including jobs, notebooks, SQL, and Unity Catalog objects.
5. Apply Git-based DevOps practices, CI/CD, and Databricks Asset Bundles to safely promote changes across environments.
6. Implement monitoring, alerting, runbooks, incident response, and root-cause analysis.
7. Enforce governance and security using Unity Catalog (lineage, classification, ACLs, row/column-level security).
8. Define and maintain data-quality rules, expectations, and SLOs within pipelines.
9. Support root-cause analysis of data anomalies and production issues.
10. Partner with Product Owner, Product Manager, and business stakeholders to translate requirements into functional and non-functional delivery scope.
11. Collaborate with IT platform teams to define data contracts, SLAs, and schema evolution strategies.
12. Produce clear technical documentation (data contracts, source-to-target mappings, release notes).
Essential Skills & Experience:
13. 6+ years in data engineering or advanced analytics engineering roles.
14. Strong hands-on expertise in Python and SQL.
15. Proven experience building production pipelines in Databricks.
16. Excellent attention to detail, with the ability to create effective documentation and process diagrams.
17. Solid understanding of data modelling, performance tuning, and cost optimisation.
Desirable Skills & Experience:
18. Hands-on experience with Databricks Lakehouse, including Delta Lake and Delta Live Tables for batch/stream pipelines.
19. Knowledge of pipeline health monitoring, SLA/SLO management, and incident response.
20. Unity Catalog governance and security expertise, including lineage, table ACLs, and row/column-level security.
21. Familiarity with Databricks DevOps/DataOps practices (Git-based development, CI/CD, automated testing).
22. Performance and cost optimization strategies for Databricks (autoscaling, Photon/serverless, partitioning, Z-Ordering, OPTIMIZE/VACUUM).
23. Semantic layer and metrics engineering experience for consistent business metrics and self-service analytics.
24. Experience with cloud-native analytics platforms (preferably Azure) operating as enterprise-grade production services.
