Do Work That Matters

Technology at CommBank is helping build simpler, safer and more personalised banking experiences. This role sits within Customer Data Technologies and the Customer Lifecycle Management team, which supports Know Your Customer refresh processes across the bank.

As a Staff Software Engineer, you’ll help build an in-house solution that enables customers to complete their identity refresh digitally, through a branch or with support from back-office teams. You’ll lead technical delivery across integration and backend engineering, helping modernise the platform while improving security, reliability and the customer experience.

See yourself in our team

You’ll join a highly capable and collaborative team of backend, frontend and data engineers delivering strategic Customer Lifecycle Management capabilities. The team is moving from a vendor-led platform towards an in-house solution built around modern engineering practices and stronger integration with bank channels.

Working in a squad technical leadership capacity, you’ll partner with product owners, principal engineers and senior stakeholders. You’ll also guide colleagues across Australia and India, to align priorities, remove technical blockers and support consistent delivery.

In this role, you will:

• Lead the technical design and delivery of backend and integration services.
• Design, build and operate Java microservices and REST APIs on AWS and Amazon EKS.
• Help shape event-driven solutions that integrate Customer Lifecycle Management capabilities with bank channels.

• Embed DevSecOps, automated testing, observability and reliable CI/CD practices.
• Provide technical direction, unblock delivery and help the squad make sound engineering decisions.
• Mentor software and senior software engineers, strengthening quality, consistency and engineering capability.
• Collaborate with product, business and technology stakeholders to translate complex needs into practical solutions.

We’re interested in hearing from people who:

You’re an experienced software engineer who combines deep backend expertise with pragmatic technical leadership. You can move comfortably between architecture, hands-on engineering, operational ownership and coaching, while keeping customer, security and compliance outcomes front of mind.

You’ll bring:

• Strong hands-on Java software engineering and system design experience.
• Demonstrated experience designing and operating microservices and REST APIs in production.
• Practical AWS and Amazon EKS experience, including containerised workloads.
• Experience with CI/CD and Git-based development, ideally using GitHub Actions.
