Create your best future and join Westpac an Engineer.
What's the role?
This role sits within the Customer & Engineering unit, delivering customer servicing, credit assessment, and product originations technology via online and staff‑facing channels. In addition to maintaining group‑critical applications, you will help drive the adoption of AI‑driven, agentic development across Java APIs, Python services, and Informatica Intelligent Data Management Cloud (IDMC) pipelines—automating coding, testing, documentation, and change delivery while meeting the bank's regulatory and security obligations.
Your key responsibilities include:
* Design and implement RESTful APIs in Java (Spring), using clean architecture and robust design patterns.
* Build Python services and developer tooling for AI‑assisted and agentic workflows (code/test/doc generation, CI/CD integration).
* Design, build, and operate IDMC pipelines (Cloud Data Integration & Application Integration) for customer master, data integration, and event‑driven interfaces.
* Engineer for non‑functional excellence across reliability, security, performance, observability, and operability.
* Collaborate effectively with engineers and stakeholders in complex project environments.
* Adhere to Westpac standards and processes to meet regulatory obligations.
* Apply an AI‑first approach to automate coding, testing, data mappings, orchestration, and documentation; orchestrate multi‑agent workflows with guardrails, policy checks, and evaluation metrics (e.g., code quality, test coverage, traceability).
What do I need?
* A degree in Computer Science (or a closely related field) with a major in Software Engineering, or equivalent experience.
* Strong results in programming and application design.
* Experience in designing, developing, and implementing RESTful APIs.
* Expert-level proficiency in Java and Python.
* Experience with Informatica IDMC.
* Proficiency with Git and Bitbucket.
* Experience with Spring and Jersey frameworks.
* Experience with AI agentic development.
