Principal Software Engineer- Digitisation and Enablement

Do work that matters

At CommBank, we’re building the technology that powers how the organisation delivers outcomes at scale.

Within Digitisation & Enablement, we’re transforming how platforms, systems, and capabilities are designed, built, and delivered across the enterprise. Our focus is on enabling faster, simpler, and more resilient technology outcomes that directly support business objectives, while contributing to helping the Australian community grow and thrive.

As a Principal Software Engineer, you’ll shape technology strategy and architecture across multiple teams, helping define how modern platforms are built, scaled, and evolved in a complex enterprise environment.

This is an opportunity to influence engineering at scale, drive meaningful transformation, and play a key role in evolving how technology supports business outcomes.

See yourself in our team

You’ll join a high-impact engineering environment focused on building and evolving enterprise platforms and capabilities.

Working across multiple squads, you’ll connect the dots across systems, guide architectural decisions, and ensure we’re building scalable, secure, and resilient solutions that meet long-term needs.

Partnering with senior engineering leaders, architects, product leaders, and engineering managers, you’ll align technical direction to strategy; while staying close enough to delivery to influence outcomes where it matters most.

What you’ll do

Technical Strategy & Architecture

Co-create and evolve technology strategy and roadmaps aligned to business objectives

Define architectural direction across platforms, services, and systems

Ensure solutions meet long-term scalability, reliability, security, and operability goals

Guide modernisation of enterprise systems and platform evolution

Cross-Team Technical Leadership

Provide technical leadership across multiple squads and domains

Identify opportunities for reuse, simplification, and standardisation

Resolve complex cross-domain engineering challenges

Influence engineering roadmaps and investment decisions

Engineering Excellence

Champion engineering standards, patterns, and best practices

Drive improvements in quality, observability, automation, and reliability

Lead architecture reviews and governance practices

Enable teams to move independently while maintaining platform consistency

Leadership & Influence

Mentor Staff Engineers and senior engineers across the organisation

Build engineering capability through coaching and knowledge sharing

Partner with product, architecture, and business stakeholders

Act as a trusted advisor to senior engineering leadership

We’re looking for people who

Have significant experience leading large-scale platforms and distributed systems

Have proven success driving technical strategy across multiple teams

Bring deep expertise in cloud-native architecture and modern engineering practices

Can balance immediate delivery with long-term platform evolution

Influence through technical credibility rather than authority

Have experience building shared platforms, reusable services, or enterprise

Capabilities

Technical capability

You don’t need expertise in everything we use, but strong fundamentals and depth in modern engineering are essential.

Core Engineering

Java / Spring Boot

Distributed systems and API-driven architectures

Workflow & Orchestration

Temporal (or similar platforms)

Enterprise workflow and integration patterns

Cloud & Platform

AWS (including Lambda and cloud-native architectures)

Scalable, resilient platform design

Emerging & Intelligent Systems

Python

Agentic AI patterns and frameworks

Agent SDKs and orchestration tools (e.g. LangGraph or similar)

Engineering Environment

GitHub (CI/CD, collaboration, and delivery pipelines)

Modern DevOps and automation practices

Why this role is different

You won’t just influence a single team, you’ll shape how engineering is done across the organisation.

You’ll play a critical role in defining technology direction, influencing strategy, and enabling step-change improvements in how platforms are built, scaled, and operated using modern tooling, AI, and evolving architectural approaches.
