You are an experienced MLOps Engineer who is passionate about machine learning platforms, automation, and cloud-native AI solutions.
We’re looking to set the standard for a world-class, self-service, secure, and scalable MLOps platform that enables rapid experimentation and safe production deployment of ML and Generative AI models.
Together, we can build state-of-the-art AI and LLM platforms that drive seamless, responsible experiences for millions of customers.
Do work that matters
Retail Banking Services (RBS) is the public face of CommBank, delivering a seamless banking experience for the future to our 10 million+ personal and small business customers. We offer market-leading products and services, supported by some of the world’s best systems, platforms, and engineering practices.
As a Senior MLOps Engineer, you will apply modern engineering and MLOps practices to operationalise machine learning and Large Language Models (LLMs) at scale. The role provides a strong opportunity to contribute to AI platform uplift, cloud adoption, and enterprise-grade ML enablement on AWS.
See yourself in our team
The RBS Customer Remediation crew is responsible for identifying root causes of issues, implementing control mitigations with Lines of Business, and ensuring customers are fully refunded for any bank error. We work closely with Group Customer Advocacy & Remediation (GCAR), Internal Audit, and Risk partners to deliver fair and positive outcomes for customers.
As part of this crew, the Senior MLOps Engineer will enable reliable, compliant, and observable ML solutions that support remediation analytics, automation, and decisioning use cases.
Your responsibilities will include:
Design, build, and maintain end-to-end MLOps pipelines for training, testing, deployment, and monitoring of ML and LLM models.
Operationalise models using AWS SageMaker, including training jobs, pipelines, model registry, batch inference, and real-time endpoints.
Support LLM and Generative AI workloads, including fine-tuning, inference optimisation, and deployment patterns.
Develop and maintain CI/CD pipelines for ML workflows and platform components.
Implement monitoring and observability for models and pipelines (data drift, model performance, system health).
Automate and improve ML development, release, and operational processes.
Take ownership of production support and technical troubleshooting for ML platforms and services.
Drive continuous improvement in platform reliability, security, cost, and performance.
Collaborate with data scientists and engineers to build robust ML pipelines that can handle large datasets and traffic.
Maintain security adherence and compliance standards, including data privacy and model explainability.
Ensure clear and comprehensive documentation of MLOps processes, infrastructure, along with configurations.
Participate as a senior member of the engineering team with minimal supervision and strong ownership and provide mentoring and technical assistance to other members of the team.
