Principal Software Engineer
Join our Principal Software Engineer Talent Community at CommBank
What is the Talent Community?
At CommBank, we're looking for exceptional engineering leaders who want to build, scale and modernise technology that impacts millions of Australians every day.
We are currently hiring for a few Principal Software Engineer roles across a number of teams within Engineering and joining our Principal Software Engineer Talent Community will help to connect you with relevant opportunities.
Roles are based in Sydney or Melbourne (with some flexibility depending on the team) and sit across our diverse engineering domains within the Group.
As part of our engineering community, you'll design and deliver enterprise‐grade systems at scale — improving customer experiences, strengthening platform resilience and enabling the future of digital banking.
Engineering at CommBank
At CommBank, we operate at national scale — with nearly half of all Australian transactions flowing through our systems. Our engineers solve complex, high‐impact problems across modern cloud platforms, distributed systems and data‐intensive applications.
You'll work in an environment that blends greenfield innovation with large‐scale modernisation, supported by strong engineering leadership and a deep investment in technology capability.
We partner closely across product, data and platform teams, and continue to invest in emerging technologies including AI, real‐time systems and cloud‐native architectures to deliver secure, resilient and customer‐first solutions.
Who we're looking for
At CommBank, our values of Care, Courage and Commitment guide everything we do — for our customers, our communities and each other.
We're building a community of Principal Engineers who embody these values — combining deep technical expertise with strong leadership, sound judgement and a passion for building high‐quality systems at scale.
Show Care Through Engineering Excellence
You design and build systems with customers, reliability and long‐term sustainability in mind — setting high standards for quality, security and operational excellence.
Demonstrate courage in complex environments
You thrive on solving ambiguous, high‐stakes problems — challenging the status quo, making pragmatic technical decisions, and influencing senior stakeholders through clear reasoning and experience.
Live commitment to craft and continuous improvement
You bring deep, hands‐on expertise across modern software engineering practices, with a track record of delivering large‐scale systems and evolving platforms over time.
Lead through influence and mentorship
You're a technical leader who uplifts others — guiding engineers, shaping engineering culture, and driving alignment across multiple teams without relying on authority alone.
Operate at scale
You have experience designing, building and running distributed systems in production — balancing delivery pace with reliability, resilience and long‐term architecture.
Collaborate across disciplines
You work effectively with product, design, data and platform teams — contributing to end‐to‐end solutions that deliver meaningful business and customer outcomes.
Take ownership and drive outcomes
You are self‐motivated and accountable, comfortable leading complex initiatives from concept through to delivery and ongoing operation.
