Software Engineer - Data | Data Mesh & Lakehouse

About the Role

We are looking for a Software Engineer - Data to join a central Data Delivery team building the foundation of a global Data Mesh platform based on a Lakehouse architecture.

You will work on the engineering layer responsible for ingesting, processing and provisioning source-aligned data products into central data catalogs, enabling teams across the organisation to consume trusted data for analytics, reporting, machine learning and other data-driven applications.

A key part of the platform is enabling scalable data consumption through zero-copy data sharing, while maintaining strong governance, security and data quality standards.

What You'll Be Working On

• Design and build scalable batch and streaming data pipelines.
• Develop ingestion solutions for source-aligned data products.
• Work with Apache Spark and Databricks within a modern Lakehouse environment.
• Implement data ingestion strategies including Full Loads, Delta Loads and Change Data Capture (CDC).
• Build and maintain streaming pipelines using technologies such as Kafka, Flink or Confluent.
• Manage datasets stored across Google Cloud Storage and Azure Blob Storage.
• Enable secure zero-copy data sharing through technologies such as Databricks Unity Catalog and BigQuery.
• Implement data governance and access-control models including RBAC and attribute-based access control.
• Design solutions capable of handling complex schema evolution, including backward and forward compatibility.
