Staff Software Engineer - Full Stack (Node.JS, Typescript, API, React)

• We're transforming home lending with cloud-native engineering, quality and automation.
• You have Staff-level expertise across TypeScript, Node.js, React, APIs and architecture.
• Together we will build scalable technology that makes home ownership simpler and faster.

Do work that matters:

At Bankwest, we’re reimagining the home loan experience by building modern, scalable origination platforms that make the journey from application through approval and settlement simpler and faster. As a Staff Software Engineer, Full Stack, you’ll work across the full engineering lifecycle, staying close to customers, understanding real pain points and turning complex lending challenges into intuitive digital experiences. You’ll combine deep technical expertise with strategic leadership, helping shape technical direction and architecture while remaining hands-on in designing, building and evolving the platform.

This is a build-focused role with genuine end-to-end ownership, where you’ll influence architecture, accelerate delivery and raise engineering standards across our Home Loan Origination ecosystem. You’ll solve meaningful problems at scale, guide technical decisions across teams and help engineers navigate complexity without losing sight of the customer outcome. It’s an opportunity to lead through engineering, not just direction, creating technology that has a tangible impact on how customers achieve one of life’s biggest milestones: owning a home.

See yourself in our team:

The Home Loan Origination Chapter, within the wider Seamless Lending Crew, is transforming the technology behind one of the biggest moments in our customers’ lives, buying a home. We’re modernising our core home lending services, platforms and digital experiences to make the journey simpler, faster and more seamless for new and existing customers.

We’re building and scaling cloud-native home loan origination platforms, spanning digital applications, broker and lender workflows, credit and decisioning integrations, verification and document orchestration, and event-driven processing. Working with technologies including TypeScript, Node.js and PostgreSQL, you’ll help shape the future of home lending and build technology that makes the Australian dream of home ownership easier to achieve.

We’re interested in hearing from people who:

• Operate at Staff Engineer level, providing hands-on technical leadership across architecture, design, code and engineering standards.
• Design scalable, modular, API-first and event-driven architectures, translating complex business workflows into production-ready solutions.
• Bring strong TypeScript and Node.js full-stack expertise, including React, Next.js and NestJS.
• Have deep PostgreSQL experience, including schema design, indexing, transactional performance and optimisation at scale.
• Lead delivery end to end, from discovery and technical design through build, test, deployment, production ownership and continuous improvement.
• Champion a build it, deploy it, run it, own it mindset, supported by DevSecOps, CI/CD, automated testing and secure-by-design engineering.
• Balance speed, scalability, reliability and security, making pragmatic technical trade-offs while driving rapid concept-to-production delivery.
• Influence engineers and teams through strong technical credibility, mentoring, architectural direction and modern engineering best practice.
• Ideally bring experience in regulated financial services, home lending or mortgage origination, although this is highly regarded rather than essential.
• Experience with AI agentic engineering and AI-powered orchestration using LangChain or similar frameworks are highly regarded.
