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.

Highly flexible, hybrid working. Melbourne or Sydney based. Salary negotiable to $200k + Super. Australian work rights are essential. Apply with your CV?
