Staff Software Engineer - Consumer Cards

We're building tomorrow’s bank today!

Do work that matters

As a Staff Software Engineer role at the core of Consumer Finance, you will help build, simplify and modernise the products, processes and infrastructure that underpin CBAs cards offering. You will work on critical capabilities such as credit card Netbank next and commsee 2.0, transforming the whole user experience and cards journey. You’ll design and build scalable applications on AWS, while delivering modern and intuitive front end using TypeScript and Next.js, including emerging AI-powered experiences.

This role goes beyond hands-on delivery into technical leadership and strategic influence. You’ll help shape the engineering roadmap, drive technical uplift across squads, and raise standards in cloud-native design, full‑stack engineering and modern development practices. Partnering closely with senior and executive leaders, you’ll turn strategy into outcomes while mentoring engineers and contractors, and growing capability across the crew. The work is fast paced, highly collaborative and constantly evolving, with real customer impact at scale. If you’re motivated by solving complex problems and building technology people rely on daily, this is a role where your expertise truly matters.
