Are you passionate about building great software, refining engineering practices, and helping others do their best work? We're looking for a Senior Developer to help shape and deliver exceptional developer experiences across Westpac.
You'll join a polyglot engineering team building The Westpac Mesh—a digital platform that enables developers to easily discover, build, deploy, and run future‐ready applications. This includes creating AI‐enabled tooling and agentic workflows that reduce toil, improve productivity, and support high‐quality software delivery. Alongside hands‐on engineering, you'll help set technical direction and mentor others in building great software.
What's The Role
* Building high‐quality software that delights a large internal developer community
* Designing and improving developer platforms, tools, libraries, and build processes
* Developing AI‐enabled developer tooling such as search, summarisation, and copilots, with strong evaluation, observability, security, and guardrails
* Implementing agentic workflows to safely automate repetitive engineering tasks (with human‐in‐the‐loop where required)
* Shaping the technical direction of products and mentoring junior engineers
* Identifying and helping remove technical and delivery impediments
* Contributing to and fostering a vibrant technical community
What Do I Need
* Over 5 years experience as a polyglot software engineer
* Strong experience building APIs and microservices in Java, with exposure to Node.js or Python
* Experience integrating AI capabilities into platforms, including agentic patterns, tool use, and workflow orchestration
* Desirable to have an understanding of public cloud platforms (Azure and/or AWS)
* Familiarity with SaaS technologies such as Kafka or MongoDB (desirable)
* Practical experience applying AI/LLMs in production environments (e.g. RAG, prompt/tool design, model integration), including testing and responsible AI practices (desirable)
* Passion for agile engineering practices such as TDD, pair programming, and continuous delivery
Why join us?
* 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.
