Let’s introduce ourselves

We’re a venture-scaler powered by CommBank. That means we build, buy, and invest in startups that could benefit the bank’s 15 million customers and beyond.

Because of what we do, we’re really neither corporate, nor startup – instead we’re happily navigating the space between both worlds. We're close enough to benefit from the bank’s strategy, scale and stability, but separate enough that we have the autonomy to try new things. To be a sandbox for change

What about your team?

We are looking for a Senior Software Engineer with knowledge and a broad range of concepts, technology, and domain insights to develop and deliver world-class software solutions.

You will be primarily responsible for building software in fast-paced, greenfields environments, using the latest cloud tooling & frameworks to create early stage prototypes & MVP releases that help advance business cases for new products.

Along with the initial build, there is an expectation you can help establish and evolve these initiatives to help expand our portfolio of ventures.

  • Design, implement, and run mobile applications, ensuring seamless integration across front-end & back-end with high test coverage

  • Implement and maintain robust CI/CD pipelines and Infrastructure as Code for mobile applications

  • Proactively identify, prioritize, and address technical debt, ensuring sustainable code quality and alignment with long-term project goals

  • Take initiative and provide expert guidance to the business on how to scope & develop new products
