Responsibilities

  • ● 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.
  • ● See yourself in our team
  • ● The Consumer Cards Transformation crew is a tight knit, highly technical group within CBA's broader Consumer Finance Domain, focused on building and evolving our Consumer card products and overall platform. This chapter owns critical card platforms and underlying BIAN based service domain APIs, that process millions of transactions every day, operating at scale, under constant demand and with zero tolerance for failure. The team works end to end across modern, cloud based systems, covering card authorisation, clearing, cards administration and operation and cards inquiry, ensuring customers can use their cards for their day-to-day needs.

  • ● Design, build and operate robust, scalable, cloud native solutions using Next.js, Typescript, GraphQL, .NET, C, AWS
  • ● Influence and evolve platform architecture, including microservices, event driven integrations and cloud native deployment patterns
  • ● Champion engineering standards and best practices across software engineering processes
  • ● Lead high quality delivery through CI/CD, test automation, observability and strong DevSecOps practices
  • ● Bring a strong AI enablement mindset, with hands on exposure to AI assisted tooling and a clear drive to continuously upskill
  • ● Apply AI assisted development and emerging agentic patterns to lift developer productivity and improve system design
  • ● We don't expect you to know everything, but experience in several of the following areas will set you up for success:
  • ● Front End: Hands on Next.js (must have), typescript
  • ● Back End: C, .NET, PostgreSQL or other relational databases, REST APIs
  • ● API Design & Integration: RESTful APIs, OpenAPI, API versioning, contract first design, API design patterns
