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.
