About the company
•
We’re building modern banking and lending platforms that power real-time customer experiences
•
You bring Staff-level engineering excellence with strong banking, lending or financial-platform experience
•
Together we deliver resilient, scalable systems across home lending systems
Do work that matters:
We’re Unloan a forward-thinking business looking to revolutionise the lending industry. We’re a modern, agile, standalone brand backed by the Commonwealth Bank and we’re building the future of digital home lending. Step into a Staff Software Engineer role at Unloan, working at the core of digital home lending in the InLife Crew’s Core Banking Squad. You will shape the systems that power the live lending experience, from repayments and redraw to account servicing, reliability, and control across the full lifecycle. This is where modern banking-platform engineering meets lending and account servicing, demanding precision, resilience, strong system design and meaningful domain understanding. You will lead across strategy, architecture, design, and delivery while staying hands on, building secure, scalable services with TypeScript, Next.js, Node.js, GraphQL, and cloud native platforms.
Responsibilities
Your impact will be measured in how well these core systems perform in the moments that matter most for customers and the business. You will drive real execution, mentoring engineers, setting high standards, and owning outcomes from concept through to production in a true build it own it environment. With a strong systems mindset, you will help evolve a platform that is reliable, intelligent, and ready to scale, while enabling faster innovation through automation and modern engineering practices. Backed by CommBank and powered by a bold digital brand, this is an opportunity to apply deep technical expertise to meaningful problems and help define the future of home lending.
See yourself in our team:
The Unloan InLife Crew owns Unloan’s home lending platform, building and operating the capabilities that power the entire loan lifecycle, from new lending and refinancing through to in-life servicing and day‑to‑day loan management. This is Engineering at scale: solving complex, domain‑heavy problems, processing high‑volume transactions, and integrating deeply with CBA’s broader ecosystem.
Their systems are engineered for precision, resilience and performance, because every repayment, rate change and redraw depends on these systems working reliably for customers and integrating safely with bank’s broader banking ecosystem. Every interaction flows through what they build, and their impact is seen in every seamless transaction and every reliable outcome. Joining this team means working at the centre of that impact, tackling meaningful technical challenges, building enterprise‑grade capabilities that continuously evolve, and contributing to a platform customers rely on every day.
We’re interested in hearing from people who:
•
Bring deep hands-on engineering expertise across TypeScript, Node.js, GraphQL, REST APIs and modern web technologies to build and ship high-quality digital banking products end-to-end.
•
Have strong back-end foundations with full-stack capability, owning the full lifecycle from ideation through to production operations in a true “you build it, you run it” environment.
•
Design and scale resilient, high-integrity distributed systems that support complex financial workflows, high-volume transactions, observability, reliability and operational control.
•
Lead modernisation initiatives, transforming legacy platforms into API-first, cloud-native, event-driven architectures aligned to enterprise engineering standards
•
Apply AI and automation pragmatically and responsibly where they improve engineering productivity, customer outcomes or operational effectiveness, with strong consideration for security, privacy and regulatory constraints.
•
Connect engineering decisions to business outcomes, balancing risk, compliance and profitability while optimising for customer experience in digital banking journeys
•
Lead through ambiguity and complexity, driving cross-team technical initiatives, shaping architecture strategy, and delivering clarity and momentum at scale
•
Elevate engineering capability by mentoring others, setting high technical standards, and fostering a culture of continuous learning, experimentation and disciplined delivery
