Organization

At CommBank, we never lose sight of the role we play in other people’s financial wellbeing. Our focus is to help people and businesses move forward, to progress, make the right financial decisions, and achieve their dreams, targets and aspirations. Regardless of where you work within our organisation, your initiative, talent, ideas and energy all contribute to the impact that we can make with our work. Together, we can achieve great things.

Job Title: Gen AI Staff Software Engineer

Location: Bangalore

Business & Team

As we continue our pursuit of NPS 30, we need to transform the way we engage with our customers and colleagues. This requires a shift from a two-track digital versus assisted approach to a deeply personal and empathic end-to-end digital experience enriched and augmented by our colleagues. This will require self-healing adaptive work orchestration systems that blend the capabilities of colleagues, AI and APIs. These systems must handle the high frequency of exceptional circumstances arising during customer journeys while remaining compliant with policies and regulations, without the significant change and maintenance burden of today. The Gen AI Domain has been established to build the tools and capabilities needed across the Group, tapping into the promise of Generative AI through the “Transformer Banking” initiative.

This domain within CDAO is focused on solution practices, tools and platforms required to successfully leverage Large Language Models, rather than the tools and capabilities required to create those models. This includes technology platforms and tools such as the Gen AI Hub, RAG tooling, knowledge management services, and LLM access and control planes; business platforms and tools such as Customer Conversation Manager and Customer Activity Manager; and practice capability co-creating patterns and practices for Gen AI usage with crews across CBA.

The Gen AI Domain will provide services, tools and practices that enable crews across CBA to safely and effectively leverage Generative AI as components of more traditional solutions. We are looking for people who thrive in ambiguity, build strong team cultures, remain obsessed with customer needs, thoughtfully manage a wide variety of risks, and are passionate about transforming a large enterprise in a heavily regulated environment using Gen AI.

Impact & Contribution

As a Staff Software Engineer for Gen AI, you will use deep technical expertise in engineering principles and Gen AI platforms to achieve business outcomes. You will provide core technology and domain knowledge to inform the crew’s technical strategy and lead the design, enhancement and maintenance of solutions to complex Gen AI challenges. We are leading the world in AI ambition within Australia’s largest bank and fintech. Together, we will engineer the future of banking with innovative Gen AI solutions.
