This is a Sydney based role on Warrane, Gadigal Country, offered as a full time, permanent position with a hybrid way of working.

We’re looking for an Application Engineer who thrives in complex enterprise environment, understands system landscapes, how different systems interact end‑to‑end, and how changes propagate across integrations and downstream platforms.

• Experience in Java and Spring Boot, including developing and supporting APIs, with a solid understanding of application and integration architecture 
• Experience with integration and event‑driven technologies, including Kafka and/or MQ, and an understanding of how distributed systems interact end‑to‑end

• Strong troubleshooting and problem‑solving skills to resolve complex integration and application issues
• Hands‑on experience with Linux/Unix shell script, Oracle databases (SQL and PL/SQL), and enterprise runtime and scheduling tools such as Tomcat and Control‑M
• Exposure to infrastructure, networks, and modern technology platforms.
• Clear and effective communication skills, with experience across both packaged and custom‑built solutions.

Desirable Skills 

• Exposure to fraud, scams, or banking platforms is advantageous but not essential 
• Experience using AI‑assisted coding tools to improve development efficiency and code consistency 
• Experience working in Agile delivery environments, using tools such as JIRA and Confluence 
• Exposure to testing frameworks and test automation
