Quantexa Data Engineer | Contract | Melbourne, Sydney or Canberra (Hybrid)

My client, a global IT services and consulting provider, is looking for an experienced Quantexa Data Engineer to join a data and decision intelligence program.

You’ll build and maintain the data pipelines and integration processes behind the Quantexa platform. That means bringing together data from multiple source systems, resolving entities, and creating trusted, connected views of people, organisations, accounts and transactions. The program sits within a broader data and AI governance context, so data must be accurate, traceable and fit for enterprise risk and compliance use.

Contract summary

• Duration: 6–12 months
• Rate: Negotiable, based on experience
• Work model: Hybrid
• Location: Melbourne, Sydney or Canberra

Key responsibilities

• Ingest and prepare data from multiple internal and external sources for Quantexa
• Design, develop and maintain transformation and processing pipelines
• Map source data into Quantexa data models and entity structures
• Cleanse, standardise, validate and reconcile complex, high-volume datasets
• Configure and support entity resolution, matching and network generation
• Optimise pipelines for performance, scalability and reliability
• Troubleshoot data quality issues and pipeline or platform failures
• Embed data quality, lineage and access controls into engineering processes
• Work closely with architects, BAs, data specialists and governance stakeholders
• Support testing, release, production deployment and ongoing maintenance

Essential skills and experience

• Hands-on experience delivering Quantexa implementations as an engineer or developer
• Strong commercial data engineering background building production pipelines
• Scala and Apache Spark for large-scale distributed processing
• Strong SQL
• Data modelling, mapping and integration across disparate systems
• Understanding of entity resolution (record matching, deduplication, entity linking)
• Experience delivering into production in enterprise environments
• Clear communicator who can explain what they built, how and why

Desirable

• Quantexa certification or delivery through a Quantexa partner practice
• Financial services, financial crime, fraud, AML, risk or compliance data experience
• Network or graph analytics experience
• Cloud data platforms (AWS, Azure or GCP), Elasticsearch, Git and CI/CD
• Data governance exposure (lineage, provenance, data quality frameworks, access controls)
• Government or regulated-sector experience; an Australian Government security clearance may be an advantage, particularly for Canberra

What success looks like

You can point to a project where you received data from multiple source systems, built or modified pipelines to integrate it, resolved data quality issues, implemented entity matching and linking, and delivered a stable, performant solution into production.
