Principal Software Engineer

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 objectivesDefine architectural direction across platforms, services, and systemsEnsure solutions meet long-term scalability, reliability, security, and operability goalsGuide modernisation of enterprise systems and platform evolution Cross-Team Technical Leadership Provide technical leadership across multiple squads and domainsIdentify opportunities for reuse, simplification, and standardisationResolve complex cross-domain engineering challengesInfluence engineering roadmaps and investment decisions Engineering Excellence Champion engineering standards, patterns, and best practicesDrive improvements in quality, observability, automation, and reliabilityLead architecture reviews and governance practicesEnable teams to move independently while maintaining platform consistency Leadership & Influence Mentor Staff Engineers and senior engineers across the organisationBuild engineering capability through coaching and knowledge sharingPartner with product, architecture, and business stakeholdersAct as a trusted advisor to senior engineering leadership We’re Looking For People Who Have significant experience leading large-scale platforms and distributed systemsHave proven success driving technical strategy across multiple teamsBring deep expertise in cloud-native architecture and modern engineering practicesCan balance immediate delivery with long-term platform evolutionInfluence through technical credibility rather than authorityHave 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.
