About the work

A large federal government organisation is building out modern cloud data capability — lakehouse architecture, enterprise-scale pipelines, and curated datasets feeding reporting, analytics, AI and machine learning across the department.

There are two streams, and you can put yourself forward for either:

• Databricks stream — pipelines and ELT/ETL on the Databricks Data Intelligence Platform, Delta Lake and Medallion architecture, Unity Catalog, Databricks Workflows and Databricks SQL.

• Microsoft Fabric stream — pipelines, lakehouse solutions and data products across Fabric Data Factory, Data Engineering, Warehouse and Real-Time Analytics workloads.

This is a lead role. You'll own technical design end to end, mentor across project and operational teams, and work directly with stakeholders to turn business requirements into data solutions that actually get used.

What you'll be doing

• Designing, building and supporting enterprise-scale data pipelines and ELT/ETL solutions

• Building and optimising lakehouse architectures using Delta Lake and Medallion design patterns

• Developing ingestion frameworks for structured, semi-structured and unstructured sources

• Writing scalable transformation processes in PySpark, Spark SQL, Python and SQL

• Implementing data quality, lineage, monitoring and observability capability

• Designing dimensional and analytical data models for reporting and advanced analytics

• Curating trusted datasets that support AI and machine learning workloads

• Applying CI/CD, Infrastructure as Code and automated testing across data engineering solutions

• Providing technical leadership, mentoring and knowledge sharing

What you'll bring

Strong depth across several of the following:

Significant hands-on experience with Databricks and/or Microsoft Fabric

• Advanced PySpark, Spark SQL, Python and SQL

• Delta Lake, Unity Catalog, Databricks Workflows, Databricks SQL

• Lakehouse and Medallion architecture, and modern data engineering patterns

• Azure — ADLS Gen2, Azure Data Factory, Microsoft Fabric

• Integrating data from APIs, databases, SaaS platforms and enterprise systems

• DevOps practice — Git, CI/CD pipelines, automated testing, Azure DevOps

• Data governance, metadata management, data quality frameworks and security controls

• Supporting analytics, AI and ML workloads in an enterprise environment

Experience in an APS or other government environment is well regarded, particularly an understanding of information security, privacy, governance and recordkeeping obligations — but it is not a mandatory requirement, if you're coming from the private sector.

What's in it for you

• 12-month initial contract with 2 x 12-month extension

• Multiple positions available

• Choose your base — ACT, NSW, VIC or QLD, all hybrid with negotiable arrangements

• 40 hours per week maximum

• Estimated start late September 2026

• Baseline clearance minimum
