Staff Software Engineer (.Net, 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:
* Node.js, NestJS, ExpressJS, TypeScript
* Microservices and API integration
* Frontend
* Next.js (preferred), React, Angular, TypeScript
* AWS and Azure
* 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.
