See yourself in our team:

The Unloan InLife Crew operates at the core of Unloan’s home lending platform, owning the critical banking systems that underpin the entire customer lifecycle from new lending and refinancing through to product evolution, servicing and daytoday loan management. This team tackles complex, domain heavy problems at scale, building resilient, high performance core banking capabilities that seamlessly integrate Unloan’s digital platform with CBA’s broader enterprise ecosystem. Their work directly shapes how customers experience every interaction with their home loan, making reliability, correctness and extensibility nonnegotiable engineering outcomes.

At a Staff level, engineers in the InLife crew lead through deep technical influence, setting architectural direction, evolving platform foundations and making long term technology decisions that balance innovation with operational excellence. While Unloan is part of CBA, it functions with a strong startup mindset: autonomous, outcome driven and focused on pragmatic innovation. The team applies modern engineering practices and emerging technologies, AI, agentic AI, LLMs and automation, deliberately and thoughtfully, embedding them into core banking where they create real value. This is an environment where senior engineers shape strategy, mentor at scale, and build systems that are both enterprise grade and future ready.

We’re interested in hearing from people who: 

• Build and ship exceptional products, hands-on engineers with deep expertise across TypeScript, Next.js and GraphQL, who know what “great” looks like and deliver it.

• Lean into AI responsibly, curious and proactive about applying AI to real-world problems, hungry to experiment, learn fast, and push boundaries, while deeply understanding security, risk, privacy and safe adoption.

• Think beyond the code, connecting technical decisions to business impact, customer outcomes and commercial strategy.

• Lead through complexity, owning cross-team technical initiatives end-to-end and bringing clarity, structure and momentum to ambiguous challenges.

• Design for scale and intelligence, shaping modern architectures, distributed systems and AI-enabled platforms that are resilient, scalable and future-ready.

• Raise the bar, mentoring others, setting high standards, and lifting the capability of the entire engineering team.

• Move fast, sustainably, balancing rapid innovation with engineering discipline to deliver long-term, secure outcomes, while staying relentlessly curious about FinTech, home lending and emerging technology.
