- Together we will build tomorrow’s bank today, using world-leading engineering, technology, and innovation.
Do work that matters:
We're building tomorrow’s bank today, which means we need creative and diverse engineers to help us redefine what customers expect from a bank. Envisioning new technologies that are still waiting to be invented and reimagining products that support our customers and help build Australia’s future economy.
As a Staff Software Engineer in the Guidance & Investing Crew, you’ll be at the forefront of work that truly matters—engineering the future of how millions of customers interact with the CommBank app every single day.
As a hands‑on technology leader with full‑stack experience, you’ll lead a team of engineers designing and implementing solutions, while influencing Product Owners and Crew Tech Leads. Product‑aligned and customer‑obsessed, you’ll own what you build end‑to‑end and work with modern technologies including .NET Core, AWS, containerisation, with exposure to NodeJS / NextJS and AI‑enabled solutions.
This is your opportunity to engineer with purpose, innovate at scale, and deliver customer-first experiences that redefine digital banking.
