We're REA

REA Group ( is not your average digital business. From humble beginnings in a garage in Melbourne’s east in 1995, we have grown into a leading global digital business, specialising in property.

With bold and ambitious goals, we are changing the way the world experiences property. No matter where you're at on your property journey, we're here to help with every step - whether that's finding or financing your next home.

Our people are the key to our success. At the heart of everything we do, is a thriving culture centred around high performance and care. We are purpose driven and collaborative, which drives innovation and our ability to make a real impact.

The Data Science teams’ mission is to propel REA’s strategy through data and data science, driving largest & most engaged audiences, unparalleled data insights, and superior customer value. We combine our extensive behavioural data with property, listings, content and market data (and more) to understand our audience, customers and the market. These rich insights are then used to provide consumers personalised, relevant, contextual and timely marketing communications, content and experiences. We also use them to provide unique and powerful insights to our customers and partners, helping them better understand their audiences, leads, markets and product performance.

To do this, we develop, engineer, manage and maintain a range of machine learning models and processes, from classification models to deep learning algorithms, recommendation engines and more.

The Data Science team work closely with many teams across the business, including several teams in Consumer Product & Experience, Customer Product & Experience, PropTrack and Data Services, among others.

Support in the Design of, and then independently code, test, and deploy data science product pipelines using AWS SageMaker, Docker, Airflow, Python, BigQuery SQL, and other technologies.

Develop appropriate machine learning models to extract insights to help improve property valuations, predict user behaviour, and build personalised consumer experiences using recommendation engines.

Productionise new machine learning models and pipelines based on both structured and unstructured data (eg image and text).

Maintain and enhance existing MLOps capabilities in both the experimentation and productionisation of models, including the creation and maintenance of required cloud infrastructure.

Enable and build data and model visualisation tools for analytics and business support.

Support the design of data products in consultation with internal stakeholders

Lead and deliver project slices

Support the Senior and Lead ML engineers in ensuring quality and teamwork is being fostered in the Data Science team

Proven relevant commercial experience in ML engineering, data science or similar roles.

Tertiary qualifications in ML or data engineering, software development, data science OR equivalent experience.

Competency in Python, SQL, and/or other relevant software/languages. We’re happy for you to learn the particulars on the job, but you need to be able to code.
