Staff Platform Engineer - AI/ML Platforms

About the role

CommBank is looking for a Staff Platform Engineer in Sydney to build secure, scalable platforms that help teams move AI and machine learning capabilities from experimentation into production. The role combines deep technical expertise with hands-on engineering leadership, focusing on AI/ML operations (MLOps), self-service automation, production reliability and resource efficiency. It is a hands-on technical leadership position within a platform engineering team that treats platforms as products.

Key responsibilities

• Build and evolve AI/ML platform capabilities covering repeatable training, evaluation, deployment, serving and monitoring of models.
• Make secure delivery repeatable by embedding versioning, traceability, automated checks, controlled promotion and rollback in deployment workflows.
• Drive automation and self-service through reusable infrastructure, deployment patterns and operational tooling.
• Lead operational improvement by addressing root causes of incidents, performance issues and recurring support requests.
• Champion FinOps, making platform consumption and cost visible and helping teams understand the cost of engineering decisions.
• Optimise efficiency by improving workload scheduling, scaling, resource utilisation and capacity management.
• Embed security and operational controls into platform design with security, architecture and risk partners.
• Provide staff-level technical leadership, shaping platform roadmaps and leading complex design decisions.

Required profile

• Practical experience taking AI/ML workloads into production, including model pipelines, artefact and version management, deployment, serving and monitoring.
• Understanding of the operational needs of AI/ML workloads, such as reproducibility, data and model dependencies, compute requirements and production performance.
• Ability to translate complex requirements into secure, reusable platform capabilities.
• Experience applying reliability engineering practices, including service-level objectives, observability, capacity planning, incident response and recovery.
• An automation-first mindset, with experience eliminating recurring manual work.
• Experience applying FinOps principles, including cost allocation, consumption visibility, rightsizing and workload optimisation.
• Ability to assess cost, performance and resilience trade-offs, including the resource demands of AI/ML training and inference.
• Experience embedding security, access controls and operational governance into engineering workflows.
• Strong technical judgement, ability to influence across teams, mentor engineers and turn improvements into measurable outcomes.

Required skills

• Strong software engineering skills, including Python or another relevant language, API development, automated testing and maintainable tooling.
• Deep understanding of cloud-native engineering, containers, Kubernetes, infrastructure as code and automated delivery.
• FinOps and reliability engineering experience.
