Senior Data Scientist – Credit & Behaviour Modelling

This is a hands-on Senior Data Scientist role within a product-led fintech building consumer credit and payment products at scale.
The role sits close to core product, credit, and portfolio decisions – not as a side analytics function.

You’ll own credit and behavioural models end-to-end: from data exploration and modelling through to production deployment, monitoring, and real portfolio impact.

Salary: Up to $200k + Super
Location: Sydney or Melbourne (hybrid / remote supported)

What You’ll Be Doing

• Build, extend, and maintain credit and behavioural models used in production

• Own loan portfolio performance, including monitoring drift, stability, and outcomes

• Perform exploratory analysis and clear data visualisation for decision-making

• Partner closely with engineering to productionise models into a TypeScript-led backend

• Coach and mentor engineers and data scientists on data, modelling, and ML practices

Technology Environment

• AWS (Airflow / MWAA)

• Python for analysis and modelling

• JavaScript / TypeScript in the product layer

• SQL for analytical workflows

• Optional but valuable: S3, Glue, Athena, IAM, SageMaker

How This Role Actually Operates

• Reports directly to the CTO

• Small, high-trust team with real autonomy

• Data Science split across Melbourne, with CTO and core engineering in Sydney

• Models are expected to run in production, be monitored, and influence decisions
