• We're redefining lending with cloud native, AI driven engineering
• You have deep full stack, cloud, and architecture expertise
• Together we build secure, scalable platforms that delight users

Do work that matters:

Bankwest has a rich heritage. We’re proud to be part of the fabric of Western Australia with a strong culture built on local support. With the support of a strong partner in CBA, we share a belief in the value of our brand, our potential for growth and a big aspirational Vision.

Step into a Principal Software Engineer role within the Seamless Lending Crew, where you help reshape how customers experience lending from application to approval and beyond. Working across the full engineering lifecycle, you partner with business and technology stakeholders to modernise legacy Java and .NET platforms into secure, scalable, cloud‑native services. You bring strong architectural expertise to diagnose systems and design forward‑thinking solutions using React, Next.js, GraphQL, Node.js, and AWS. Operating at crew level, you uplift engineering practices by embedding automation, observability, security, and AI‑driven delivery into every release.

This role is meaningful because of its direct impact on customers and the organisation. Seamless Lending is focused on removing friction to make lending faster, simpler, and more accessible, while maintaining trust and reliability. As a technical leader, you guide engineers, shape architecture, and champion modern practices that elevate engineering standards. You’ll tackle high‑impact challenges such as scaling distributed systems and introducing intelligent automation, helping transform how lending products are built and delivered to create better outcomes for customers, teams, and communities.

See yourself in our team:

Bankwest's Technology Division develops and executes all technical change within the organisation ensuring the leverage of technology to deliver the Bankwest strategy. The division works on a wide variety of technologies and projects with the support of a dedicated team in an Agile methodology.

Join the Seamless Lending Crew and help reimagine one of banking’s most critical customer journeys. As Principal Engineer in Seamless Lending, you will play a pivotal role in shaping and driving the technical direction that enables faster, safer and simpler lending experiences for our customers and brokers. You will lead engineering excellence across modernisation, simplification, resilience, security and automation, helping accelerate outcomes such as 24-hour home loan approvals, smarter application and document fraud detection, and reduced operational risk. Working across squads and platforms, you will guide architectural decisions, uplift critical assets, champion DevSecOps practices, and embed AI-powered engineering to improve delivery speed, quality and developer experience.

We work in a true full cycle engineering model, where you design, build, test, release and run what you create. It is you build it, you own it culture, supported by strong DevSecOps, automation, observability and security by design. We are also embracing AI powered engineering to accelerate delivery and lift quality. This is a team with genuine ownership, technical ambition and the opportunity to deliver technology that makes a real impact.

We’re interested in hearing from people who:

• Operate as a hands-on Technical Subject Matter Expert, setting direction through deep technical credibility and leading from the front in architecture, design, and code.
• Drive strong technical leadership across crews, aligning engineers to a clear vision while influencing standards, patterns, and engineering best practice.
• Lead end-to-end innovation across the full delivery lifecycle from discovery, design, build, test, deploy, and optimise, ensuring outcomes are practical, scalable, and production ready.
• Champion a true build it, deploy it, run it, own it mindset, embedding accountability, operational ownership, and continuous improvement into every solution.
• Translate complex business challenges into executable technical strategies, making clear trade-offs and guiding teams through ambiguity with confidence.
• Stay close to the technology, actively contributing to critical code paths, architecture decisions, automation, and production problem-solving.
• Foster a culture of engineering excellence where innovation is balanced with reliability, security, compliance, and measurable business impact.
