Do work that matters
You'll help shape the next generation of our banking terminal and payments capabilities through world-class engineering and systems design. From architecting resilient distributed solutions to hands-on implementation and automation, your work will ensure our platforms are scalable, secure, and production ready – powering millions of reliable transactions across the Commonwealth Bank network.
Your focus will span
architecture, system design, software development, integration, and continuous delivery
, with a clear path toward becoming a
Full-Cycle Engineer
who drives solutions from concept to production.
See yourself in our team
The
ATM Engineering Chapter
in the
CSN Crew
is responsible for delivering robust and innovative engineering solutions that power the Bank's ATM and Digital ecosystems.
You'll work with a team of seasoned engineers to
design, build, and evolve
the core software and infrastructure that underpins our ATM network. You'll contribute to
modernising legacy systems
, improving
scalability and fault tolerance
, and ensuring seamless integration between
hardware, middleware, and payments services
.
As part of a high-performing engineering culture, you'll leverage best practices in
system architecture, observability, DevOps, and performance optimisation
, while experimenting with emerging tools and technologies to improve reliability and speed of delivery.
We're interested in hearing from people who:
Have deep experience in
system design, software architecture, and large-scale distributed systems
, ideally within payments or banking infrastructure.
Are passionate about
building end-to-end solutions
– from architectural vision and design patterns to implementation, deployment, and runtime operations.
Drive engineering excellence through
clean architecture, API design, integration patterns
, and
performance optimisation
.
Embrace
automation, CI/CD, and infrastructure as code
, enabling consistent, secure, and reliable software delivery.
Communicate early and clearly, raising design considerations and collaborating effectively across teams and stakeholders.
Value
collaboration, innovation, and ownership
, and are eager to contribute to the evolution of our engineering ecosystem.
