Senior Data Scientist

Senior Data Scientist - Modelling and Portfolio Performance Sydney or Melbourne What you will enjoy about us You will enjoy working in a technology-led fintech where modelling sits at the heart of the product - not in a back-office function.

You will enjoy owning problems end-to-end. Not just training models, but understanding how they behave in production, how they drift, and how they influence real portfolio performance.

You will enjoy being close to decision-making. This role works directly with the CTO and engineering, where ideas move quickly and models ship fast.

You will enjoy breadth. Our data science team works across multiple problem types - credit, behavioural modelling, performance analysis and optimisation - not just one narrow ML specialism.

You will enjoy impact. When you improve something here, you see it in live metrics.

The kind of work you will be doing

Build and refine credit and behavioural models

Run deep exploratory analysis across complex, messy datasets

Monitor production models and diagnose performance shifts

Analyse portfolio trends and identify performance leakage

Partner closely with engineers to deploy and iterate

Influence commercial and product decisions with structured modelling insight

This is hands‑on modelling inside a live product environment.

You will enjoy this if

You prefer product companies over institutional environments

You like models that ship and evolve - not models that sit in approval cycles

You care about statistical rigour and commercial outcomes equally

You are comfortable working inside engineering sprint cycles

You have seen real-world model behaviour and learned from it

You likely come from a tech‑led fintech, SaaS, scale‑up or consulting background where modelling directly influenced product or revenue performance.

What we work with

AWS

Airflow

Python for analysis

JavaScript and TypeScript in product

Experience deploying and monitoring models in production environments will feel natural here.

What this role is not It is not a regulatory modelling function. It is not a slow‑cycle corporate risk seat. It is not a pure research or GenAI experimentation role.

It is modelling that matters - commercially and immediately - inside a growing technology business.
