We’re undertaking a major engineering transformation, focused on building modern, cloud-native platforms that power how millions of customers connect with us through voice and digital channels.
Together, we’re building tomorrow’s bank today—using strong engineering fundamentals, modern technology, and continuous innovation.
As a Staff Software Engineer, you’ll play a key hands-on role in delivering the backend integrations, APIs, and platform capabilities that underpin a large-scale Contact Centre transformation across the Group.
You’ll work on complex, high-impact systems that unify voice and messaging channels, integrate deeply with enterprise services, and support real-time, AI-driven agent assistance—while meeting stringent security, privacy, and resilience requirements.
This role suits experienced engineers who enjoy solving ambiguous problems, working on emerging platforms, and delivering high-quality solutions in a regulated, enterprise environment.
The Agent Excellence Crew, within the Group’s Retail Technology division, designs and operates the technology that powers customer interactions across the Group’s Contact Centres.
We’re responsible for the voice and messaging platforms that support millions of customer conversations each year. Our focus is on building resilient, secure, and intelligent systems that deliver seamless customer and agent experiences.
You’ll work closely with Principal Engineers, Engineering Managers, and cross-functional partners in a collaborative, high-performing team.
Build and maintain backend services and APIs, primarily using .NET / .NET Core, integrating across multiple enterprise service domains.
Design robust, scalable, and secure integration solutions to support real-time AI-driven recommendations and workflows.
Contribute to technical design and architecture discussions, shaping solution patterns and engineering standards.
Work closely with senior technical leaders to uplift engineering excellence, code quality, and delivery outcomes.
Ensure strong observability, resilience, and operational readiness of the systems you build.
Operate with a DevSecOps mindset—you build it, test it, secure it, and help run it.
Strong backend engineering experience, ideally with .NET / C# (or any other tech stack)
Proven experience designing and building APIs and enterprise integrations.
Familiarity with frontend technologies such as React.
Experience working with cloud platforms (Azure or AWS) and core cloud hosting concepts.
Solid understanding of relational databases and data access patterns.
Exposure to AI tools or LLM concepts through work, learning, or personal projects.
We offer flexible ways of working, with roles based in Sydney or Melbourne, and a balance of in-office collaboration and flexibility.
