Principal Software Engineer - Engineering Platforms

About the role

CommBank is looking for a Principal Software Engineer to join its Engineering Pathways team, which builds and evolves software-based engineering platforms used by engineers across the bank. The role shapes platforms and tooling that help engineers build and deliver software at scale, with a strong focus on developer platforms and enterprise CI/CD. It sits within a broader ecosystem covering developer platforms, source code management, CI/CD, automation, security tooling, testing and artefact management.

Key responsibilities

• Provide technical leadership across software-based engineering platforms and developer tooling, bringing solutions together for better outcomes for engineers.
• Design, build and evolve scalable capabilities that improve how engineers develop, integrate and deliver software.
• Contribute to CI/CD and engineering tooling across source control, automation, testing and artefact management.
• Build and evolve automated delivery capabilities that let engineers move safely and efficiently from code to production.
• Work with engineers across CommBank using co-building and inner-source approaches to deliver at enterprise scale.
• Apply engineering judgement to architecture, automation, controls, standards, reliability and security.
• Solve complex technical problems and balance trade-offs to deliver sustainable solutions.
• Provide technical direction and lift engineering capability through collaboration, mentoring and pragmatic technical leadership.

Required profile

• An accomplished software engineer who has built platforms, developer tooling or engineering capabilities for other engineers, ideally at significant scale.
• A blend of strong hands-on engineering depth and the ability to set technical direction and influence across teams.
• Experience integrating engineering tooling with cloud environments; AWS, Azure or GCP experience is relevant where centred on software engineering and tooling.
• Understanding of secure software delivery practices, controls and compliance in complex technology environments.
• Experience of AI-powered engineering practices and how agentic capabilities can improve software delivery at scale.
• Ability to operate across technical boundaries, solve ambiguous problems and influence engineering decisions beyond a single squad.
• Strong learning mindset, communication and collaboration skills, with evidence of moving into new technical areas.
