Do work that matters

At CommBank, we're transforming how customers and bankers connect across digital, assisted and AI-enabled channels.

The CRM & Banker Experience Platform sits at the centre of this transformation, providing the capabilities that power customer engagement, banker workflows and intelligent service experiences across Business Banking.

As a Principal Engineer, you'll help define the future architecture of these platforms while remaining close enough to delivery to influence how they're built. You'll work across AI, CRM, workflow orchestration, cloud platforms and customer engagement services, solving complex challenges that improve both customer and colleague experiences.

This is a unique opportunity to shape the evolution of an AI-first, human-amplified engagement model where customers can move seamlessly between channels and colleagues are equipped with the right tools, insights and expertise at the right time.

See yourself in our team

Business Banking Technology executes the Technology Strategy across Business Banking through world-leading application of technology and operations. We partner closely with the business to solve real-world problems using data and AI-driven insights, resilient platforms and modern engineering practices, delivering customer value at speed and scale.

What You'll Do

• Lead the design, evolution and delivery of scalable, resilient platforms supporting customer and banker experiences.
• Drive architecture and engineering decisions across multiple squads and technology domains.
• Establish reusable engineering patterns, frameworks and standards that improve delivery speed and quality.
• Shape platform strategy across cloud, APIs, customer engagement services, workflow orchestration and AI-enabled capabilities.
• Champion modern engineering practices including DevSecOps, observability, CI/CD and automated testing.
• Partner with product, architecture, risk and business stakeholders to deliver meaningful customer and business outcomes.
• Ensure security, privacy, operational resilience and responsible AI principles are embedded into platform design and delivery.
• Mentor engineers, influence technical strategy and foster a culture of engineering excellence.

We're Interested In Hearing From People Who Have

• Experience operating as a Principal Engineer, Lead Engineer or senior technical leader within complex enterprise environments.
• A strong track record designing and delivering large-scale distributed systems and platform capabilities.
• Strong engineering judgement with the ability to balance strategic thinking and hands-on technical leadership.

• The ability to influence senior stakeholders across engineering, product, architecture, risk and business teams.
• Experience establishing engineering standards, reusable patterns and platform strategies across multiple teams.
• Strong mentoring and coaching capability, with a passion for growing engineering talent.
• Curiosity and enthusiasm for AI-enabled customer experiences, automation and modern digital platforms.

Experience within CRM, customer engagement, workflow, contact centre, digital servicing or banking environments is highly regarded but not essential.
