Job from partnerStaff Software Engineer (Nextjs, GraphQl)
Business Banking Technology | Sydney or Melbourne
- You are a deeply hands-on engineer who loves solving complex problems.
- We are high-performing engineers rebuilding Small Business Banking from the ground up.
- Together we’re building tomorrow’s business bank today.
Do work that matters
We built Australia’s number one banking app — and then rebuilt it.
Now, we’re transforming the Small Business Banking experience within NetBank. We’re creating a modern, personalised digital platform designed specifically for business customers — distinct from retail and corporate banking.
This is a rare opportunity to shape a critical rebuild at scale, used by millions of customers.
See yourself in our team
As a Staff Software Engineer, you’ll join a squad delivering the new Small Business Banking experience. You will play a key role in shaping architecture, raising engineering standards and mentoring other engineers.
This is a senior, hands-on role. You will spend the majority of your time designing and building production systems, while influencing technical direction across the crew.
You will:
Design and develop scalable microservices and APIs
Build modern front-end experiences (Next.js)
Define and influence architecture for enterprise-scale applications
Improve engineering standards, quality and secure coding practices
Guide integration with internal and third-party services
Contribute to safe deployments through CI/CD, automation and observability
Mentor engineers and uplift technical capability within the squad
Drive pragmatic, high-quality engineering decisions
We’re looking for engineers who
Are genuinely hands-on and comfortable owning complex systems end-to-end
Have strong backend engineering capability (REST APIs, microservices)
Prefer full-stack capability (Next.js/React experience highly regarded)
Have designed or contributed to enterprise-scale architecture
Understand security, reliability and performance at scale
Thrive in collaborative environments and challenge ideas constructively
Care deeply about code quality, simplicity and long-term maintainability
Actively mentor others and raise the engineering bar
Technical capability
We use a broad range of technologies. You don’t need all of them — but strong engineering fundamentals are essential.
Our ecosystem includes:
Frontend
Next.js, React, Angular, TypeScript
Backend
C# .NET Core, REST APIs, WebAPI
Node.js, NestJS, ExpressJS, TypeScript
Microservices and API integration
Cloud & DevOps
AWS and Azure
Kubernetes, Docker
CI/CD (GitHub Actions, TeamCity, Octopus, Azure DevOps)
Infrastructure as Code (CloudFormation)
Logging & observability (Splunk, monitoring tools)
Data
MSSQL, Oracle, Snowflake
NoSQL / DocumentDB
Experience with event-driven architecture (Kafka) is beneficial.
If you are a strong engineer from a different stack with proven depth, we’re open — fundamentals matter more than exact tools.
If you’re a lead engineer who still loves being deep in the code, shaping architecture and mentoring others — we’d love to hear from you.
Apply now.
We support our people with the flexibility to balance where work is done with at least half your time each month connecting in the office.
If you're already part of the Commonwealth Bank Group (including Bankwest, x15ventures), you'll need to apply through Sidekick to submit a valid application. We’re keen to support you with the next step in your career.
