Do Work That Matters

Join CommBank. Recognised as a leader in digital, engineering, data and AI, we’re investing in modern platforms, cloud, microservice-based service domains and data products that help shape the future of banking. Bring your ambition and we’ll help you grow, belong and shape what’s next in one of Australia’s most significant technology transformations.

See yourself in our team

Be part of the team driving enterprise-wide transformation at CommBank. Corporate Technology delivers the platforms, enterprise data and critical systems that power the Bank's Operations and Corporate functions. You'll collaborate across diverse teams, solve complex technology challenges and help shape the future of one of Australia's leading organisations.

As the Principal Software Engineer for the Credit Risk Profile Squad within Customer Data Services, you'll play a key role in establishing a new service and building the APIs, data products and engineering capabilities that support credit decisioning across the Bank.

This is an opportunity to lead an AI-first squad from a strong existing foundation, using GenAI as a differentiator while also driving real-time streaming, platform modernisation and resilient delivery in a critical credit-risk data domain.

What You’ll Be Doing

In this role, you'll lead a squad focused on building a cloud-based service domain with reusable APIs, data products and event-driven capabilities. Partnering closely with an Executive Product Manager, you'll lead a team of engineers across Sydney and Bengaluru to deliver secure, resilient and scalable outcomes.

• Define the engineering direction for the Credit Risk Profile squad, including target-state architecture, domain ownership and technical roadmap.

• Establish reusable APIs and data products that support credit-risk decisioning across the Bank.

• Leverage CommBank's foundational GenAI tooling to create innovative, governed solutions for credit-risk use cases.

• Champion streaming-first engineering using Apache Flink and modern event-driven architecture patterns.

• Drive legacy asset modernisation and migration into scalable, service-oriented platforms.

• Support the Crew Tech Lead by lifting engineering capability through technical leadership, coaching and consistent engineering practices.

• Partner with product, architecture and engineering teams to improve resilience, delivery flow and customer outcomes, with clear ownership for operating the services the squad builds.

We’re interested in hearing from people who:

We're looking for a highly technical engineering leader who combines deep expertise in distributed systems, data platforms, with expertise in modern software engineering and AI-enabled delivery.

• Have led full-cycle engineering in a “you build it, you run it” environment, with experience designing, building, deploying and operating software at scale.

• Bring deep technical expertise across distributed systems, data platforms and streaming-first architecture, ideally including Apache Flink.

• Have built or modernised microservice-based platforms using Java, Spring Boot, AWS, Kubernetes (EKS) and well-designed REST APIs.

• Are comfortable contributing code while setting high standards for engineering practices, code quality, patterns and architecture.

• Bring practical experience applying AI or GenAI in product, engineering or decisioning environments, with sound judgement around governance, safety and business value.

• Understand how to design and evolve service domains, reusable APIs and data products in a structured, domain-led architecture.

• Can lead modernisation and migration work across legacy and target-state platforms with clear ownership, risk awareness and delivery discipline.
