Senior Engineer - Data & Insights

Help modernise critical billing and pricing systems within a leading financial services environment

We're looking for a Senior Engineer - Data Migration & Billing Platforms to join a high-impact transformation initiative, helping migrate a legacy billing platform to a modern internally developed SaaS solution. This role is ideal for a hands-on engineer who enjoys solving complex data migration challenges, building reliable processing pipelines, and working with large-scale financial and billing datasets. While you'll be working in an AWS-hosted environment, this is not a traditional cloud data engineering or analytics role. Instead, you'll focus on data transformation, migration, validation and reconciliation to ensure the successful transition between critical billing platforms.

What you'll be doing

• Design and develop data migration and transformation pipelines to support the transition from a legacy eBilling platform to a modern SaaS billing solution.
• Build multi-stage data processing workflows that ingest, validate, enrich and transform billing and transaction data.
• Develop file-processing solutions, including CSV ingestion and generation of fixed-format output files.
• Create configuration-driven mapping frameworks to translate legacy billing structures into target platform formats.
• Implement complex pricing, fee and billing calculations, including GST treatment and payment fee structures.
• Develop robust data validation, reconciliation and exception-handling processes.
• Manage reference data, eligibility matrices, lookup tables and rate catalogues.
• Build automated testing frameworks and regression suites to ensure data quality and migration accuracy.
• Work closely with business, technology and domain stakeholders to deliver reliable migration outcomes.

What you'll bring

Strong experience delivering complex data migration, transformation or integration projects.

• Advanced Python development skills (highly preferred).
• Experience with Snowflake or Databricks.
• Experience designing and building ETL and data processing pipelines.
• Strong understanding of data mapping, transformation and reconciliation techniques.
• Experience working with structured data formats including CSV, fixed-width or batch processing files.
• Strong SQL skills and experience managing reference data and lookup tables.
• Experience implementing data validation, error-handling and data quality controls.
• Strong testing discipline, including automation, reconciliation and regression testing.
• Familiarity working within AWS environments.

Highly Desirable

• Banking, payments or financial services experience.
• Understanding of payment and billing products such as: BPAY RTGS Direct Entry NPP International Money Transfers (IMT).
• Experience working with billing, pricing or charging platforms.
• Understanding of GST treatment within financial or billing systems.
