Join Us as an AI Engineer – Transform the Future of Home Loans

What’s the role?

We’re seeking a talented and growth-driven Full Stack Engineer to join our Mortgages Technology team based in either Sydney or Gold Coast. In this role, you’ll help build scalable, secure, and intelligent digital experiences for customers applying for and managing home loans. You’ll work across the stack—from React-based front-end interfaces to API engineering and AI integration-shaping the future of mortgage services at one of Australia’s leading banks.

Key Responsibilities

- Design, develop, and maintain full-stack applications using React (UI) and Node.js/Python (API).
- Build and optimise RESTful APIs for mortgage servicing and origination workflows.
- Integrate AI-driven features such as predictive servicing, document intelligence, and conversational interfaces.
- Collaborate with product managers, designers, and data scientists to deliver seamless customer experiences.
- Participate in CI/CD pipelines, code reviews, and agile ceremonies.
- Ensure compliance with security, accessibility, and performance standards.
- Support production handovers and assist with incident resolution when required.

What do I need?

- Strong proficiency in React.js, JavaScript/TypeScript, and Node.js.
- Experience with API development, Swagger/OpenAPI, and microservices architecture.
- Programming skills in Python, with familiarity in ML libraries such as PyTorch, TensorFlow or scikit-learn.
- Hands-on experience with AI frameworks like LlamaIndex, LangChain, AutoGen, etc.
- Experience building CI/CD pipelines and automation using Jenkins, GitHub, and Bamboo.
- Exposure to AWS, Docker, and DevOps practices.
- Strong communication and stakeholder engagement skills.

Nice-to-Have:

- Familiarity with graph databases and their usage patterns.
- Understanding of large language model (LLM) architecture.
- Knowledge of fine-tuning techniques and Retrieval-Augmented Generation (RAG).
- Experience with Agentic AI frameworks and tools.
- Solid understanding of mortgage servicing workflows or financial services APIs.

Why join us?

We’re obsessed with becoming our customers #1 banking partner for life and we’re looking for people who are passionate about helping us achieve that goal. In return we’re committed to making Westpac the best place to work in the country. Here are just a few of the ways we’re already doing that:

- Special offers on banking products and discounts from top brands, including generous employee-only mortgage rates
- Flexible work arrangements to help you achieve a greater work/life balance, and a variety of leave options including Culture, Lifestyle and Wellbeing leave.
- Tailored learning and development opportunities to help your grow your career within the bank.
- Lots of opportunities to ‘give back’ to the Community by getting involved in our many volunteering initiatives

We’re all about creating a supportive and inclusive community. We welcome everyone – no matter your age, gender, background, or abilities. We also provide additional support to welcome our veterans, Indigenous Australians and neurodiverse community.
