Ingest, transform & govern data

• Ingest data from APIs, files, databases and SaaS sources into data lakes and lakehouses.
• Implement clear and testable transformation logic (data quality checks, deduplication, SCD, CDC, business rules).
• Apply data governance best practices (cataloguing, lineage, RBAC, masking of sensitive data).

Operate & optimize

• Set up CI/CD and deployment pipelines (Azure DevOps / GitHub) for Databricks assets (notebooks, jobs, pipelines, workflows).
• Using Terraform to automated IaaC setup and reusability
• Monitor, optimize and troubleshoot pipelines and clusters for performance, robustness and cost efficiency.
• Help define and implement best practices, coding standards and reusable components within the team.
