The posting

  • You're a hands-on, staff-level full-stack engineer who sets technical direction and still ships code
  • We're part of a Digital crew in Retail Banking, building the payment experiences millions of CommBank customers rely on every day
  • Together we will build tomorrow's bank today, using world-leading technology and innovation

Do work that matters

Retail Banking's digital teams build and run the channels millions of Australians use to bank every day. Our payments squads own the services behind sending, receiving and protecting money, and the platforms that keep it running securely. We treat software development as a craft and hold ourselves to industry best practice.

See yourself in our team

As a Staff Software Engineer, you'll be based in one of our payments squads in Melbourne and have influence across the wider crew. You'll design and build resilient, high-volume services, APIs and backend-for-frontend (BFF) layers on AWS that power our customers' digital experiences. If you've built native iOS or Android apps, that's a real plus, and there's room for you to contribute to ours too if you're interested.

A big part of the role is lifting the people around you. You enjoy sharing what you know, whether that's pairing, running a design review or writing a guide. You measure your success partly by how much stronger the team becomes.

You will

  • Own the technical direction for your areas, working with product and delivery leads to turn business goals into technical plans
  • Stay hands-on, designing and building microservices, BFF services, REST and GraphQL APIs, data access layers and event-driven integrations on AWS
  • Lead complex initiatives, including moving core payment capabilities onto modern platforms, from proof of concept to production
  • Set and raise engineering standards for testing, safe deployment, observability and security
  • Upskill engineers through pairing, design reviews and mentoring, and share knowledge through guilds and internal writing
  • Own what you ship in production: lead incident response and complex troubleshooting calmly, and join our on-call roster

We're interested in hearing from people who

  • Have deep, hands-on experience shipping and running back-end services, APIs and BFFs in C# .NET in production
  • Have strong, hands-on AWS experience building and operating cloud-native services in production (must have)
  • Have hands-on experience designing and building GraphQL APIs (schema design, resolvers, federation), with OData or similar query-based API experience a plus
  • Have designed systems at enterprise scale, including service boundaries, API contracts, data models and event-driven architecture, and can explain the trade-offs clearly
  • Stay calm and methodical under pressure, bringing clarity during incidents and leading blameless follow-ups
  • Are passionate about sharing knowledge and helping senior and mid-level engineers grow
  • Have led technical work across teams, bringing engineers and stakeholders along and challenging them when it matters
  • Use AI-powered engineering tools (e.g. Claude, Copilot) effectively and help others do the same

It's a bonus if you have native iOS (Swift) or Android (Kotlin) experience, have built backends for mobile clients, or know payments and fraud (transaction flows, reconciliation, and PCI DSS and APRA obligations).

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
