The Role
We are looking for an expert Senior Java Engineer to join our Corporate Technology team and take ownership of core backend systems underpinning our One Touch workforce travel experience. This is not a full‐stack role; it is a deep backend engineering position for someone who thrives building complex, high‐availability systems that process high‐volume travel workflows at scale. You will be a key technical contributor delivering critical capability uplift including change and cancellation support, waitlist management, and deep policy engine integration across systems that run 24/7 for some of Australia's largest mining and resources operators.
What You\'ll Do
* Design, build, and own complex backend services and APIs using Java (Spring Boot / Spring Framework), with a strong focus on reliability, performance, and correctness
* Deliver new modules including: change and cancellation processing, waitlist capability, and policy engine integration across the workforce travel platform
* Implement and consume RESTful APIs and SOAP/Web Services that integrate with airline GDS systems, internal booking engines, and third‐party workforce platforms
* Build robust, fault‐tolerant service components capable of handling high‐volume, time‐critical travel booking workflows
System Reliability & Observability
* Ensure the platform maintains high uptime as a mission‐critical system for workforce travel operations
* Instrument services with Datadog, including APM tracing, custom metrics, log correlation, and dashboard creation for full observability
* Define and monitor SLOs/SLIs, respond to incidents, and lead post‐incident reviews to drive reliability improvements
* Proactively identify and resolve performance bottlenecks, memory issues, and degradation patterns before they impact customers
Architecture & Technical Leadership
* Lead technical design for new capabilities, producing clear architecture and API design documentation before implementation
* Conduct rigorous code reviews and uphold high standards for API design, exception handling, test coverage, and service contract quality
* Identify and reduce technical debt, particularly around legacy integration patterns, file‐based data exchange, and monolithic components
* Mentor and support junior and mid‐level engineers on Java best practices, Spring internals, and API design
DevOps & Delivery
* Champion DevOps practices across the team: CI/CD pipeline ownership, automated testing (unit, integration, contract), and deployment hygiene
* Collaborate with platform and cloud engineering on Azure‐based infrastructure, ensuring services are containerised, scalable, and maintainable
* Work closely with product managers and business stakeholders to translate complex travel workflow requirements into clean, maintainable backend logic
* Participate actively in agile delivery processes, sprint planning, refinement, and retrospectives to drive continuous improvement
About You Essential
* 7+ years of professional software engineering experience with deep expertise in Java (Java 11+, ideally Java 17 or 21)
* Expert‐level knowledge of the Spring ecosystem: Spring Boot, Spring MVC, Spring Data JPA, Spring Security, and Spring Integration
* Strong track record designing and building complex REST APIs and Web Services (SOAP/WSDL); including versioning, contract design, and error handling at scale
* Experience building and maintaining business‐critical backend systems with complex workflows; multi‐step processing, state machines, async handling, or saga patterns
* Proven ability to instrument and operate production systems using Datadog — APM, dashboards, monitors, log pipelines
* Solid understanding of DevOps practices: CI/CD pipeline ownership, automated testing strategies, code quality gates, and deployment automation
* Experience with relational databases (MySQL, PostgreSQL, or Sybase) including complex query optimisation and schema design
* Strong communication skills and ability to translate business requirements into technical solutions
* Proficient with AI coding tools (Claude, GitHub Copilot) and able to critically evaluate AI‐generated code in production contexts
Highly Regarded
* Experience in travel technology GDS systems (Amadeus, Sabre, Galileo), NDC, PNR management
* Background in workforce management, resource scheduling, FIFO logistics
* Event‐driven architecture experience (Kafka, Azure Service Bus, RabbitMQ)
* Familiarity with API gateways, service mesh, microservices strategies
* Azure cloud experience: App Services, AKS, Service Bus, Application Insights
Tech Stack
* Java 17 / 21, Spring Boot, Spring Framework
* REST APIs, SOAP / Web Services (WSDL), JSON, XML
* Spring MVC, Spring Data JPA, Spring Security, Spring Integration
* MySQL, Sybase, SQL query optimisation
* Datadog (APM, dashboards, monitors, log pipelines, SLOs)
* Azure (App Services, AKS, Service Bus, Storage)
* GitHub, Azure DevOps, Jenkins, automated CI/CD pipelines
* JUnit, Mockito, integration and contract testing
Why Join Us
* Work on systems that directly impact thousands of FIFO workers, mission‐critical technology with real‐world impact
* A true senior engineering role with technical ownership and architectural influence
* A collaborative engineering culture focused on craft, honesty, and continuous improvement
What You\'ll Enjoy
* Competitive salary: $150k-165k Plus Super (dependent on experience)
