Machine Learning Engineer

Bailey Abbott Pty Ltd; Perth; On-site; AUD 120,000 - 180,000; Full time

Job summary

Bailey Abbott Pty Ltd in Perth, Australia is seeking a Machine Learning Engineer with a strong software engineering foundation to productionise, scale, and maintain advanced analytical and predictive models.

You will bridge the gap between data science experimentation and robust software engineering, designing scalable data pipelines and automated ML lifecycles within our Databricks environment using Spark, R, and modern engineering practices.

Qualifications

• Solid foundation in core software engineering principles (design patterns, unit/integration testing, Git version control, CI/CD pipelines).
• Proven hands-on experience orchestrating workloads in Databricks (MLflow, Unity Catalog).
• Deep practical understanding of Spark internals, data partitioning, query optimization, and memory management.
• Strong proficiency in R for production analytics using Spark integrations (sparklyr, SparkR).
• Experience querying relational data and working with Delta Lake formats.

Responsibilities

• Production ML pipelines: Build, test, and optimize production-grade data processing and model training pipelines in Apache Spark and Databricks.
• MLOps & lifecycle automation: Standardise model deployment, versioning, monitoring, and automated retraining workflows (CI/CD, MLflow).
• Code quality & architecture: Apply software engineering best practices—modular code, automated testing, containerisation, and version control.
• R & statistical workloads: Optimise and scale R-based modeling workflows over distributed data using Sparklyr/SparkR.
• Collaboration & integration: Partner with data architects and engineers to integrate predictive outputs into downstream analytics.
• Performance & reliability: Monitor pipeline latency, manage compute sizing, ensure data governance in production.

Role Overview

We are seeking a Machine Learning Engineer with a strong software engineering foundation to productionise, scale, and maintain advanced analytical and predictive models. In this role, you will bridge the gap between data science experimentation and robust software engineering, designing scalable data pipelines and automated ML lifecycles within our Databricks environment using Spark, R, and modern engineering practices.

Key Responsibilities

• Production ML Pipelines: Build, test, and optimize production-grade data processing and model training pipelines in Apache Spark and Databricks.

• MLOps & Lifecycle Automation: Standardise model deployment, versioning, monitoring, and automated retraining workflows (CI/CD, MLflow).
• Code Quality & Architecture: Apply software engineering best practices—modular code architecture, automated testing, containerisation, and version control to analytical and statistical codebases.
• R & Statistical Workloads: Optimise and scale R-based modeling workflows to run efficiently over distributed data architectures using Sparklyr/SparkR.
• Collaboration & Integration: Partner with data architects, data engineers, and domain analysts to integrate predictive outputs cleanly into downstream systems and analytical platforms.
• Performance & Reliability: Monitor pipeline latency, manage compute cluster sizing, and ensure data integrity and governance across production workspaces.

Required Skills & Experience

• Software Engineering Fundamentals: Solid foundation in core software engineering principles (design patterns, unit/integration testing, Git version control, CI/CD pipelines).
• Databricks Ecosystem: Proven hands-on experience orchestrating workloads, managing workspaces, and using MLflow / Unity Catalog within Databricks.
• Distributed Computing (Apache Spark): Deep practical understanding of Spark internals, data partitioning, query optimization, and memory management.
• R for Production / Advanced Analytics: Strong proficiency in R (including Spark integrations like sparklyr or SparkR) for statistical modeling, forecast automation, or data manipulation.
• Data Layer Experience: Comfort querying complex relational data, working with Delta Lake formats, and handling large-scale time-series or tabular datasets.

Desirable Skills

• Familiarity with Python/PySpark alongside R for cross-language workflows.
• Experience with cloud infrastructure (Azure, AWS, or GCP) and Infrastructure as Code (Terraform).
• Understanding of model drift detection, data lineage, and enterprise data governance frameworks.

Our clients are diverse and so are we. We engage with great talent from all walks of life to bring their extensive and varied experience to help promote innovation. We encourage applications from candidates from all backgrounds to further strengthen Bailey Abbott.
